    Adding two complex numbers in Java In this program we have a class ComplexNumber. In this class we have two instance variables real and img to hold the real and imaginary parts of complex numbers. We have declared a method sum() to add the two numbers by adding their real and imaginary parts together. The constructor of this class is used for…

    Java program to generate a random string Output In the above example, we have first created a string containing all the alphabets. Next, we have generated a random index number using the nextInt() method of the Random class. Using the random index number, we have generated the random character from the string alphabet. We then used the StringBuilder class to append…

    Check if a string is numeric Output In the above program, we have a String named string that contains the string to be checked. We also have a boolean value numeric which stores if the final result is numeric or not. To check if the string contains numbers only, in the try block, we use Double‘s parseDouble() method to convert the string to a Double. If it…

    Binary numbers are numbers consisting only of 2 digits: 0 and 1. They can be expressed in the base 2 numeral system. For example, Decimal numbers are numbers consisting of 10 digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. They can be expressed in the base 10 numeral system. Here, we will be writing a Java program that will convert a binary number into decimal and vice versa using built-in methods and custom…
