Java true and false

true and false

The boolean data type is boolean.

class Main {
  public static void main(String[] args) {
    int number = 5;
  if (isEven(number)) {
    System.out.println(number + "Even");
  } else {
    System.out.println(number + "Odd");
  public static boolean isEven(int a) {
    return a % 2 == 0;

In the above, the isEven method checks if the argument value is even and returns true if it is even and false if it is odd.
