Output: The output depends on the input number provided by the user. For instance: If the user enters 4, the output will be: 4 is an even number.; If the user enters 7, the output will be: 7 is an odd number.; Method 3: Using Bitwise Operators. Bitwise operators OR, AND, and XOR can be used for checking even odd program in Java. .odd even java program Output: The output depends on the input number provided by the user.

We prompt the user to enter a number using System.out.printf method and read the input using Scanner.nextInt method.Enter an integer number:: 12 12 is an even number. Enter an integer number:: 9 9 is an odd number. In this program, we used the if-else statement to check the number is even or not. The if-else statement in Java is a selection statement.An odd number has a "1" as its singles digit, an even number had a zero there.
