In this tutorial, you’ll learn about different types of operators in Java, their syntax and how to use them with the help of examples.<\/p>\n\n\n\n

Operators are symbols that perform operations on variables and values. For example, +<\/code> is an operator used for addition, while *<\/code> is also an operator used for multiplication.<\/p>\n\n\n\n

Operators in Java can be classified into 5 types:<\/p>\n\n\n\n

  1. Arithmetic Operators<\/li>
  2. Assignment Operators<\/li>
  3. Relational Operators<\/li>
  4. Logical Operators<\/li>
  5. Unary Operators<\/li>
  6. Bitwise Operators<\/li><\/ol>\n\n\n\n
    \n\n\n\n

    1. Java Arithmetic Operators<\/h2>\n\n\n\n

    Arithmetic operators are used to perform arithmetic operations on variables and data. For example,<\/p>\n\n\n\n

    a + b;<\/code><\/pre>\n\n\n\n
    Here, the +<\/code> operator is used to add two variables a<\/var> and b<\/var>. Similarly, there are various other arithmetic operators in Java.<\/p>\n\n\n\n
    Operator<\/td>Operation<\/td><\/tr>
    +<\/code><\/td>Addition<\/td><\/tr>
    -<\/code><\/td>Subtraction<\/td><\/tr>
    *<\/code><\/td>Multiplication<\/td><\/tr>
    \/<\/code><\/td>Division<\/td><\/tr>
    %<\/code><\/td>Modulo Operation (Remainder after division)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Example 1: Arithmetic Operators<\/h3>\n\n\n\n
    class Main {\n  public static void main(String[] args) {\n    \n    \/\/ declare variables\n    int a = 12, b = 5;\n\n    \/\/ addition operator\n    System.out.println(\"a + b = \" + (a + b));\n\n    \/\/ subtraction operator\n    System.out.println(\"a - b = \" + (a - b));\n\n    \/\/ multiplication operator\n    System.out.println(\"a * b = \" + (a * b));\n\n    \/\/ division operator\n    System.out.println(\"a \/ b = \" + (a \/ b));\n\n    \/\/ modulo operator\n    System.out.println(\"a % b = \" + (a % b));\n  }\n}<\/code><\/pre>\n\n\n\n
    Output<\/strong><\/p>\n\n\n\n
    a + b = 17\na - b = 7 \na * b = 60\na \/ b = 2 \na % b = 2 <\/samp><\/code><\/pre>\n\n\n\n
    In the above example, we have used +<\/code>, -<\/code>, and *<\/code> operators to compute addition, subtraction, and multiplication operations.<\/p>\n\n\n\n
    \/ Division Operator<\/strong><\/p>\n\n\n\n
    Note the operation, a \/ b<\/code> in our program. The \/<\/code> operator is the division operator.<\/p>\n\n\n\n
    If we use the division operator with two integers, then the resulting quotient will also be an integer. And, if one of the operands is a floating-point number, we will get the result will also be in floating-point.<\/p>\n\n\n\n
    In Java,\n\n(9 \/ 2) is 4\n(9.0 \/ 2) is 4.5\n(9 \/ 2.0) is 4.5\n(9.0 \/ 2.0) is 4.5<\/code><\/pre>\n\n\n\n
    % Modulo Operator<\/strong><\/p>\n\n\n\n
    The modulo operator %<\/code> computes the remainder. When a = 7<\/code> is divided by b = 4<\/code>, the remainder is 3<\/strong>.<\/p>\n\n\n\n
    Note<\/strong>: The %<\/code> operator is mainly used with integers.<\/p>\n\n\n\n
    \n\n\n\n
    2. Java Assignment Operators<\/h2>\n\n\n\n
    Assignment operators are used in Java to assign values to variables. For example,<\/p>\n\n\n\n
    int age;\nage = 5;<\/code><\/pre>\n\n\n\n
    Here, =<\/code> is the assignment operator. It assigns the value on its right to the variable on its left. That is, 5<\/strong> is assigned to the variable age<\/var>.<\/p>\n\n\n\n
    Let’s see some more assignment operators available in Java.<\/p>\n\n\n\n
    Operator<\/th>Example<\/th>Equivalent to<\/th><\/tr>
    =<\/code><\/td>a = b;<\/code><\/td>a = b;<\/code><\/td><\/tr>
    +=<\/code><\/td>a += b;<\/code><\/td>a = a + b;<\/code><\/td><\/tr>
    -=<\/code><\/td>a -= b;<\/code><\/td>a = a - b;<\/code><\/td><\/tr>
    *=<\/code><\/td>a *= b;<\/code><\/td>a = a * b;<\/code><\/td><\/tr>
    \/=<\/code><\/td>a \/= b;<\/code><\/td>a = a \/ b;<\/code><\/td><\/tr>
    %=<\/code><\/td>a %= b;<\/code><\/td>a = a % b;<\/code><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Example 2: Assignment Operators<\/h3>\n\n\n\n
    class Main {\n  public static void main(String[] args) {\n    \n    \/\/ create variables\n    int a = 4;\n    int var;\n\n    \/\/ assign value using =\n    var = a;\n    System.out.println(\"var using =: \" + var);\n\n    \/\/ assign value using =+\n    var += a;\n    System.out.println(\"var using +=: \" + var);\n\n    \/\/ assign value using =*\n    var *= a;\n    System.out.println(\"var using *=: \" + var);\n  }\n}<\/code><\/pre>\n\n\n\n
    Output<\/strong><\/p>\n\n\n\n
    var using =: 4\nvar using +=: 8 \nvar using *=: 32<\/samp><\/code><\/pre>\n\n\n\n
    \n\n\n\n
    3. Java Relational Operators<\/h2>\n\n\n\n
    Relational operators are used to check the relationship between two operands. For example,<\/p>\n\n\n\n
    \/\/ check if a is less than b\na < b;<\/code><\/pre>\n\n\n\n
    Here, <<\/code> operator is the relational operator. It checks if a<\/var> is less than b<\/var> or not.<\/p>\n\n\n\n
    It returns either true<\/code> or false<\/code>.<\/p>\n\n\n\n
    Operator<\/th>Description<\/th>Example<\/th><\/tr>
    ==<\/code><\/td>Is Equal To<\/td>3 == 5<\/code> returns false<\/strong><\/td><\/tr>
    !=<\/code><\/td>Not Equal To<\/td>3 != 5<\/code> returns true<\/strong><\/td><\/tr>
    ><\/code><\/td>Greater Than<\/td>3 > 5<\/code> returns false<\/strong><\/td><\/tr>
    <<\/code><\/td>Less Than<\/td>3 < 5<\/code> returns true<\/strong><\/td><\/tr>
    >=<\/code><\/td>Greater Than or Equal To<\/td>3 >= 5<\/code> returns false<\/strong><\/td><\/tr>
    <=<\/code><\/td>Less Than or Equal To<\/td>3 <= 5<\/code> returns true<\/strong><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Example 3: Relational Operators<\/h3>\n\n\n\n
    class Main {\n  public static void main(String[] args) {\n    \n    \/\/ create variables\n    int a = 7, b = 11;\n\n    \/\/ value of a and b\n    System.out.println(\"a is \" + a + \" and b is \" + b);\n\n    \/\/ == operator\n    System.out.println(a == b);  \/\/ false\n\n    \/\/ != operator\n    System.out.println(a != b);  \/\/ true\n\n    \/\/ > operator\n    System.out.println(a > b);  \/\/ false\n\n    \/\/ < operator\n    System.out.println(a < b);  \/\/ true\n\n    \/\/ >= operator\n    System.out.println(a >= b);  \/\/ false\n\n    \/\/ <= operator\n    System.out.println(a <= b);  \/\/ true\n  }\n}<\/code><\/pre>\n\n\n\n
    Note<\/strong>: Relational operators are used in decision making and loops.<\/p>\n\n\n\n
    \n\n\n\n
    4. Java Logical Operators<\/h2>\n\n\n\n
    Logical operators are used to check whether an expression is true<\/code> or false<\/code>. They are used in decision making.<\/p>\n\n\n\n
    Operator<\/th>Example<\/th>Meaning<\/th><\/tr>
    &&<\/code> (Logical AND)<\/td>expression1 &&<\/strong> expression2<\/td>true<\/code> only if both expression1<\/var> and expression2<\/var> are true<\/code><\/td><\/tr>
    ||<\/code> (Logical OR)<\/td>expression1 ||<\/strong> expression2<\/td>true<\/code> if either expression1<\/var> or expression2<\/var> is true<\/code><\/td><\/tr>
    !<\/code> (Logical NOT)<\/td>!<\/strong>expression<\/td>true<\/code> if expression<\/var> is false<\/code> and vice versa<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    Example 4: Logical Operators<\/h3>\n\n\n\n
    class Main {\n  public static void main(String[] args) {\n\n    \/\/ && operator\n    System.out.println((5 > 3) && (8 > 5));  \/\/ true\n    System.out.println((5 > 3) && (8 < 5));  \/\/ false\n\n    \/\/ || operator\n    System.out.println((5 < 3) || (8 > 5));  \/\/ true\n    System.out.println((5 > 3) || (8 < 5));  \/\/ true\n    System.out.println((5 < 3) || (8 < 5));  \/\/ false\n\n    \/\/ ! operator\n    System.out.println(!(5 == 3));  \/\/ true\n    System.out.println(!(5 > 3));  \/\/ false\n  }\n}<\/code><\/pre>\n\n\n\n
    Working of Program<\/strong><\/p>\n\n\n\n
    • (5 > 3) && (8 > 5)<\/code> returns true<\/code> because both (5 > 3)<\/code> and (8 > 5)<\/code> are true<\/code>.<\/li>
    • (5 > 3) && (8 < 5)<\/code> returns false<\/code> because the expression (8 < 5)<\/code> is false<\/code>.<\/li>
    • (5 < 3) || (8 > 5)<\/code> returns true<\/code> because the expression (8 > 5)<\/code> is true<\/code>.<\/li>
    • (5 > 3) && (8 > 5)<\/code> returns true<\/code> because the expression (5 > 3)<\/code> is true<\/code>.<\/li>
    • (5 > 3) && (8 > 5)<\/code> returns false<\/code> because both (5 < 3)<\/code> and (8 < 5)<\/code> are false<\/code>.<\/li>
    • !(5 == 3)<\/code> returns true because 5 == 3<\/code> is false<\/code>.<\/li>
    • !(5 > 3)<\/code> returns false because 5 > 3<\/code> is true<\/code>.<\/li><\/ul>\n\n\n\n
      \n\n\n\n
      5. Java Unary Operators<\/h2>\n\n\n\n
      Unary operators are used with only one operand. For example, ++<\/code> is a unary operator that increases the value of a variable by 1<\/strong>. That is, ++5<\/code> will return 6<\/strong>.<\/p>\n\n\n\n
      Different types of unary operators are:<\/p>\n\n\n\n
      Operator<\/th>Meaning<\/th><\/tr>
      +<\/code><\/td>Unary plus<\/strong>: not necessary to use since numbers are positive without using it<\/td><\/tr>
      -<\/code><\/td>Unary minus<\/strong>: inverts the sign of an expression<\/td><\/tr>
      ++<\/code><\/td>Increment operator<\/strong>: increments value by 1<\/td><\/tr>
      --<\/code><\/td>Decrement operator<\/strong>: decrements value by 1<\/td><\/tr>
      !<\/code><\/td>Logical complement operator<\/strong>: inverts the value of a boolean<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
      Increment and Decrement Operators<\/h2>\n\n\n\n
      Java also provides increment and decrement operators: ++<\/code> and --<\/code> respectively. ++<\/code> increases the value of the operand by 1<\/strong>, while --<\/code> decrease it by 1<\/strong>. For example,<\/p>\n\n\n\n
      int num = 5;\n\n\/\/ increase num by 1\n++num;<\/code><\/pre>\n\n\n\n
      Here, the value of num<\/var> gets increased to 6<\/strong> from its initial value of 5<\/strong>.<\/p>\n\n\n\n
      \n\n\n\n
      Example 5: Increment and Decrement Operators<\/h3>\n\n\n\n
      class Main {\n  public static void main(String[] args) {\n    \n    \/\/ declare variables\n    int a = 12, b = 12;\n    int result1, result2;\n\n    \/\/ original value\n    System.out.println(\"Value of a: \" + a);\n\n    \/\/ increment operator\n    result1 = ++a;\n    System.out.println(\"After increment: \" + result1);\n\n    System.out.println(\"Value of b: \" + b);\n\n    \/\/ decrement operator\n    result2 = --b;\n    System.out.println(\"After decrement: \" + result2);\n  }\n}<\/code><\/pre>\n\n\n\n
      Output<\/strong><\/p>\n\n\n\n
      Value of a: 12\nAfter increment: 13\nValue of b: 12     \nAfter decrement: 11<\/samp><\/code><\/pre>\n\n\n\n
      In the above program, we have used the ++ and — operator as prefixes (++a, –b)<\/strong>. We can also use these operators as postfix (a++, b++)<\/strong>.<\/p>\n\n\n\n
      There is a slight difference when these operators are used as prefix versus when they are used as a postfix.<\/p>\n\n\n\n
      <\/p>\n\n\n\n
      \n\n\n\n
      6. Java Bitwise Operators<\/h2>\n\n\n\n
      Bitwise operators in Java are used to perform operations on individual bits. For example,<\/p>\n\n\n\n
      Bitwise complement Operation of 35\n\n35 = 00100011 (In Binary)\n\n~ 00100011 \n  ________\n   11011100  = 220 (In decimal)<\/code><\/pre>\n\n\n\n
      Here, ~<\/code> is a bitwise operator. It inverts the value of each bit (0<\/strong> to 1<\/strong> and 1<\/strong> to 0<\/strong>).<\/p>\n\n\n\n
      The various bitwise operators present in Java are:<\/p>\n\n\n\n
      Operator<\/th>Description<\/th><\/tr>
      ~<\/code><\/td>Bitwise Complement<\/td><\/tr>
      <<<\/code><\/td>Left Shift<\/td><\/tr>
      >><\/code><\/td>Right Shift<\/td><\/tr>
      >>><\/code><\/td>Unsigned Right Shift<\/td><\/tr>
      &<\/code><\/td>Bitwise AND<\/td><\/tr>
      ^<\/code><\/td>Bitwise exclusive OR<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
      These operators are not generally used in Java. <\/p>\n\n\n\n
      \n\n\n\n
      Other operators<\/h2>\n\n\n\n
      Besides these operators, there are other additional operators in Java.<\/p>\n\n\n\n
      Java instanceof Operator<\/h3>\n\n\n\n
      The instanceof<\/code> operator checks whether an object is an instanceof a particular class. For example,<\/p>\n\n\n\n
      class Main {\n  public static void main(String[] args) {\n\n    String str = \"Programiz\";\n    boolean result;\n\n    \/\/ checks if str is an instance of\n    \/\/ the String class\n    result = str instanceof String;\n    System.out.println(\"Is str an object of String? \" + result);\n  }\n}<\/code><\/pre>\n\n\n\n
      Output<\/strong><\/p>\n\n\n\n
      Is str an object of String? true<\/samp><\/pre>\n\n\n\n
      Here,\u00a0str<\/var>\u00a0is an instance of the\u00a0String<\/code>\u00a0class. Hence, the\u00a0instanceof<\/code>\u00a0operator returns\u00a0true<\/code>. <\/p>\n\n\n\n
      \n\n\n\n
      Java Ternary Operator<\/h3>\n\n\n\n
      The ternary operator (conditional operator) is shorthand for the if-then-else<\/code> statement. For example,<\/p>\n\n\n\n
      variable = Expression ? expression1 : expression2<\/code><\/pre>\n\n\n\n
      Here’s how it works.<\/p>\n\n\n\n
      • If the Expression<\/code> is true<\/code>, expression1<\/code> is assigned to the variable<\/var>.<\/li>
      • If the Expression<\/code> is false<\/code>, expression2<\/code> is assigned to the variable<\/var>.<\/li><\/ul>\n\n\n\n
        Let’s see an example of a ternary operator.<\/p>\n\n\n\n
        class Java {\n  public static void main(String[] args) {\n\n    int februaryDays = 29;\n    String result;\n\n    \/\/ ternary operator\n    result = (februaryDays == 28) ? \"Not a leap year\" : \"Leap year\";\n    System.out.println(result);\n  }\n}<\/code><\/pre>\n\n\n\n
        Output<\/strong><\/p>\n\n\n\n
        Leap year<\/samp><\/code><\/pre>\n\n\n\n
        In the above example, we have used the ternary operator to check if the year is a leap year or not. <\/p>\n","protected":false},"excerpt":{"rendered":"
