Thread: while instead of if-else

Hello Fahad,

Welcome to the Java Programming Forums

How about this?

import javax.swing.*;
 
public class Main {
 
	public static void main(String[] args) {
 
		[B]boolean locked = true;[/B]
		String name;
		String passw;
 
		name = JOptionPane.showInputDialog("Enter Your Name Please: ");
 
		[B]while (locked) {[/B]
			if (name.equals("fahad")) {
 
				passw = JOptionPane.showInputDialog("Your Password: ");
 
				if (passw.equals("123")) {
					JOptionPane.showMessageDialog(null, "Welcome " + name
							+ " Successful Login");
					[B]locked = false;[/B]
				}
 
				else {
					JOptionPane.showMessageDialog(null,
							"Incorrect input, please exit the program!! ");
				}
 
			} else {
				JOptionPane.showMessageDialog(null,
						"Incorrect input, please exit the program!! ");
			}
		[B]}[/B]
	}
}

You could do something like this:

import javax.swing.*;
 
public class Main {
 
	public static void main(String[] args) {
 
		boolean nameLocked = true;
		String name;
 
		name = JOptionPane.showInputDialog("Enter Your Name Please: ");
 
		while (nameLocked) {
 
			if (name.equals("fahad")) {
 
				nameLocked = false;
				passBox();
 
			} else {
 
				name = JOptionPane
						.showInputDialog("Incorrect Username! Enter Your Name Please: ");
			}
 
		}
 
	}
 
	public static void passBox() {
 
		boolean passLocked = true;
		String passw;
 
		while (passLocked) {
			passw = JOptionPane.showInputDialog("Your Password: ");
 
			if (passw.equals("123")) {
				JOptionPane.showMessageDialog(null, "Successful Login");
				passLocked = false;
 
			}
 
			else {
				JOptionPane.showMessageDialog(null,
						"Incorrect input, please exit or re enter password ");
			}
 
		}
 
	}
}
