Compare String with/without using equals() method.

import java.util.Scanner;

public class CompareString{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        System.out.println("Enter the 1st String: ");
        String s1 = in.next();
        System.out.println("Enter the 2nd String: ");
        String s2 = in.next();

        //1st approach without using equals() method
        System.out.println("*********compare by 1st approach************");
        if(s1.length()==s2.length()){
            for(int i=0; i<s1.length(); i++){
                if(s1.charAt(i)!=s2.charAt(i)){
                    System.out.println("String "+s1+" is not equal to string "+s2);
                    break;
                }
            }

        }else{
            System.out.println("String "+s1+" is not equal to string "+s2);
        }

        //2nd approach , just use equals() method
        System.out.println("*********compare by 2nd approach************");
        if(s1.equals(s2)){
            System.out.println("String "+s1+" is equal to string "+s2);
        }else{

        }   
    }
}

output-

Enter the 1st String:
selenium
Enter the 2nd String:
selenium
*********compare by 1st approach************
String selenium is equal to string selenium
*********compare by 2nd approach************
String selenium is equal to string selenium
