Java program to return boolean value

Boolean value means "True" or "False". Our task is write a function which accepts an integer and returns a Boolean value "True" if the number passed is even number or "False" if the number passed is an odd number.


Output:

Enter a number to check even or odd: 5
number 5 is odd

Implementation:

/* Let us consider an example boolean function which checks whether a number is even or odd */ import java.util.*; import java.lang.*; import java.io.*; class CodeRegister { /* return boolean true if number is even return boolean false if number is odd */ public static boolean checkoddeven(int n) { /* check the number is even or odd */ if(n%2==0) { return true; } else { return false; } } public static void main (String[] args) throws java.lang.Exception { /* Scanner class to get the input from the user through console or keyboard */ Scanner in = new Scanner(System.in); System.out.println("Enter a number to check even or odd:"); int n = in.nextInt(); /* compare the function result with boolean true or false */ if(checkoddeven(n)==true) { System.out.println("number "+n+" is even"); } else { System.out.println("number "+n+" is odd"); } } }
