In this tutorial, you will learn about the continue statement and labeled continue statement in Java with the help of examples.<\/p>\n\n\n\n
While working with loops, sometimes you might want to skip some statements or terminate the loop. In such cases, break<\/code> and continue<\/code> statements are used.<\/p>\n\n\n\n
To learn about the\u00a0break<\/code>\u00a0statement, visit\u00a0Java break. Here, we will learn about the\u00a0continue<\/code>\u00a0statement.<\/p>\n\n\n\n\n\n\n\n
Java continue<\/h2>\n\n\n\n
The continue<\/code> statement skips the current iteration of a loop (for<\/code>, while<\/code>, do...while<\/code>, etc).<\/p>\n\n\n\n
After the continue<\/code> statement, the program moves to the end of the loop. And, test expression is evaluated (update statement is evaluated in case of the for loop).<\/p>\n\n\n\n
Here’s the syntax of the continue statement.<\/p>\n\n\n\n
continue;<\/code><\/pre>\n\n\n\n
Note<\/strong>: The continue statement is almost always used in decision-making statements (if…else Statement).<\/p>\n\n\n\n\n\n\n\n
Working of Java continue statement<\/h2>\n\n\n\nWorking of Java continue Statement<\/figcaption><\/figure>\n\n\n\n\n\n\n\n
Example 1: Java continue statement<\/h3>\n\n\n\n
class Main {\n public static void main(String[] args) {\n\n \/\/ for loop\n for (int i = 1; i <= 10; ++i) {\n\n \/\/ if value of i is between 4 and 9\n \/\/ continue is executed\n if (i > 4 && i < 9) {\n continue;\n }\n System.out.println(i);\n }\n }\n}<\/code><\/pre>\n\n\n\n
Output<\/strong>:<\/p>\n\n\n\n
1\n2\n3\n4\n9\n10<\/samp><\/code><\/pre>\n\n\n\n
In the above program, we are using the\u00a0for<\/code>\u00a0loop to print the value of\u00a0i<\/var>\u00a0in each iteration. To know how\u00a0for<\/code>\u00a0loop works, visit\u00a0Java for loop. Notice the statement,<\/p>\n\n\n\n
if (i > 4 && i < 9) {\n continue;\n}<\/code><\/pre>\n\n\n\n
Here, the continue<\/code> statement is executed when the value of i<\/var> becomes more than 4<\/strong> and less than 9<\/strong>.<\/p>\n\n\n\n
It then skips the print statement for those values. Hence, the output skips the values 5<\/strong>, 6<\/strong>, 7<\/strong>, and 8<\/strong>.<\/p>\n\n\n\n\n\n\n\n
Example 2: Compute the sum of 5 positive numbers<\/h3>\n\n\n\n
import java.util.Scanner;\n\nclass Main {\n public static void main(String[] args) {\n\n Double number, sum = 0.0;\n \/\/ create an object of Scanner\n Scanner input = new Scanner(System.in);\n\n for (int i = 1; i < 6; ++i) {\n System.out.print(\"Enter number \" + i + \" : \");\n \/\/ takes input from the user\n number = input.nextDouble();\n\n \/\/ if number is negative\n \/\/ continue statement is executed\n if (number <= 0.0) {\n continue;\n }\n\n sum += number;\n }\n System.out.println(\"Sum = \" + sum);\n input.close();\n }\n}<\/code><\/pre>\n\n\n\n
Output<\/strong>:<\/p>\n\n\n\n
Enter number 1: 2.2\nEnter number 2: 5.6\nEnter number 3: 0\nEnter number 4: -2.4\nEnter number 5: -3\nSum = 7.8<\/samp><\/code><\/pre>\n\n\n\n
In the above example, we have used the for loop to print the sum of 5 positive numbers. Notice the line,<\/p>\n\n\n\n
if (number < 0.0) {\n continue;\n}<\/code><\/pre>\n\n\n\n
Here, when the user enters a negative number, the continue<\/code> statement is executed. This skips the current iteration of the loop and takes the program control to the update expression of the loop.<\/p>\n\n\n\n
<\/p>\n\n\n\n
\n\n\n\n
Java continue with Nested Loop<\/h2>\n\n\n\n
In the case of\u00a0nested loops in Java, the\u00a0continue<\/code>\u00a0statement skips the current iteration of the innermost loop.<\/p>\n\n\n\nWorking of Java continue statement with Nested Loops<\/figcaption><\/figure>\n\n\n\n\n\n\n\n
Example 3: continue with Nested Loop<\/h3>\n\n\n\n
class Main {\n public static void main(String[] args) {\n\n int i = 1, j = 1;\n\n \/\/ outer loop\n while (i <= 3) {\n\n System.out.println(\"Outer Loop: \" + i);\n\n \/\/ inner loop\n while(j <= 3) {\n\n if(j == 2) {\n j++;\n continue;\n }\n\n System.out.println(\"Inner Loop: \" + j);\n j++;\n }\n i++;\n }\n }\n}<\/code><\/pre>\n\n\n\n
In the above example, we have used the nested\u00a0while loop. Note that we have used the\u00a0continue<\/code>\u00a0statement inside the inner loop.<\/p>\n\n\n\n
Here, when the value of j<\/var> is 2<\/strong>, the value of j<\/var> is increased and the continue<\/code> statement is executed.<\/p>\n\n\n\n
This skips the iteration of the inner loop. Hence, the text Inner Loop: 2<\/var> is skipped from the output.<\/p>\n\n\n\n\n\n\n\n
Labeled continue Statement<\/h2>\n\n\n\n
Till now, we have used the unlabeled continue<\/code> statement. However, there is another form of continue<\/code> statement in Java known as labeled continue<\/strong>.<\/p>\n\n\n\n
It includes the label of the loop along with the continue<\/code> keyword. For example,<\/p>\n\n\n\n
continue label;<\/code><\/pre>\n\n\n\n
Here, the continue<\/code> statement skips the current iteration of the loop specified by label<\/var>.<\/p>\n\n\n\nWorking of the Java labeled continue Statement<\/figcaption><\/figure>\n\n\n\n
We can see that the label identifier specifies the outer loop. Notice the use of the continue inside the inner loop.<\/p>\n\n\n\n
Here, the continue<\/code> statement is skipping the current iteration of the labeled statement (i.e. outer loop). Then, the program control goes to the next iteration of the labeled statement.<\/p>\n\n\n\n\n\n\n\n
Example 4: labeled continue Statement<\/h3>\n\n\n\n
class Main {\n public static void main(String[] args) {\n\n \/\/ outer loop is labeled as first\n first:\n for (int i = 1; i < 6; ++i) {\n\n \/\/ inner loop\n for (int j = 1; j < 5; ++j) {\n if (i == 3 || j == 2)\n\n \/\/ skips the current iteration of outer loop\n continue first;\n System.out.println(\"i = \" + i + \"; j = \" + j);\n }\n }\n }\n}<\/code><\/pre>\n\n\n\n
In the above example, the labeled continue<\/code> statement is used to skip the current iteration of the loop labeled as first<\/var>.<\/p>\n\n\n\n
if (i==3 || j==2)\n continue first;<\/code><\/pre>\n\n\n\n
Here, we can see the outermost for<\/code> loop is labeled as first<\/var>,<\/p>\n\n\n\n
first:\nfor (int i = 1; i < 6; ++i) {..}<\/code><\/pre>\n\n\n\n
Hence, the iteration of the outer for<\/code> loop is skipped if the value of i<\/var> is 3 or the value of j<\/var> is 2.<\/p>\n\n\n\n
Note<\/strong>: The use of labeled\u00a0continue<\/code>\u00a0is often discouraged as it makes your code hard to understand. If you are in a situation where you have to use labeled\u00a0continue<\/code>, refactor your code and try to solve it in a different way to make it more readable.<\/p>\n","protected":false},"excerpt":{"rendered":"
