Simple login validation for Java Programming

Description: Membuat java program yang memvalidasi saat login sebelum masuk atau melanjutkan command / statement line selanjutnya.

Tutorial :
1. Masukkan code dibawah ini pada class anda

import java.util.*;

public class LoginValidation {

public static void login() {

Scanner in = new Scanner(;

boolean validation;
String username, password;

do {
         System.out.println("Login First!");
         System.out.print("\nInput your login ID: ");
         username = in.nextLine();
         System.out.print("Input your password: ");
         password = in.nextLine();         
         if(username.equals("testuser") && loginpw.equals("testpassword")) {
            validation = true;
            System.out.println("You are successfully login!");
         else {
            validation = false;
            System.out.println("Your ID or Password didn't match!");
         } while(validation == false);


public static void main(String[]args) {





1. Kalian bisa ganti dibagian ini :

if(username.equals("testuser") && loginpw.equals("testpassword"))

testuser adalah username yang digunakan saat login dan testpassword merupakan password yang digunakan saat login.

2. Bisa ganti dibagian string statement atau print dll.
