public class Main {
  public static void main(String[] args) {
    int x = 10;
    int y = 20;

    // Compare if x is less than y
    System.out.println(x < y);   // true (10 < 20)

    // Compare if x is equal to y
    System.out.println(x == y);  // false (10 is not equal to 20)

    // Extra examples:
    System.out.println(x > y);   // false (10 > 20? no)
    System.out.println(x != y);  // true  (10 is not equal to 20)
    System.out.println(x <= y);  // true  (10 <= 20)
    System.out.println(x >= y);  // false (10 >= 20? no)

Demo Operator

public class Main {
  public static void main(String[] args) {
    // Instead of reading from Scanner, we assign fixed values
    int x = 12;
    int y = 5;

    boolean cmp1 = x < y;
    boolean cmp2 = x == y;
    boolean bothPositive = (x > 0 && y > 0);
    boolean eitherZero = (x == 0 || y == 0);
    boolean inRangeX = (10 <= x && x <= 20);

    System.out.println("x < y: " + cmp1);
    System.out.println("x == y: " + cmp2);
    System.out.println("bothPositive: " + bothPositive);
    System.out.println("eitherZero: " + eitherZero);
    System.out.println("10 <= x <= 20: " + inRangeX);

    // Short-circuit guard example
    String s = (x > 5) ? "big" : null;
    if (s != null && s.equals("big")) {
      System.out.println("s is big");
