• Boolean value true, if both the objects are identical
• Else it returns false.

Example 1

public class JavaIntegerEqualsExample1 {
   public static void main(String[] args) {
    Integer byte1=127;
    Integer byte2=607;
    //It compares two Integer objects numerically
    boolean val=byte1.equals(byte2);
    if(val){
        System.out.println(byte1+" and "+byte2+" values are equal.");
    }
    else{
        System.out.println(byte2+" and "+byte1+" are not equal.");
       }
    }}

Output

607 and 127 are not equal.

Example 2

import java.util.Scanner;
public class JavaIntegerEqualsExample2 {
    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.print("Enter your password : ");
        Integer val1=scanner.nextInt();
        System.out.print("Re-Enter your password : ");
        Integer val2=scanner.nextInt();
        Boolean val=val1.equals(val2);
        if (val){
            System.out.println("New Password confirmed! Your password Matched. ");
            String str =val1.toString();
            if (str.length()>7){
                System.out.println("Its a Strong password");
            }
            else{
                System.out.println("Its a weak password");
            }
        }
        else {
            System.out.println("Retry! Your password didn't matched.");
        }
    }
