عندي مشكله بالبرنامج

السلام عليكم

المقارنه بين two object

بتكون بــ equals.

يعنى علشان اقارن t1 , t2

كدا

t1.equals(t2);

لان كدا

t1==t2;

بيقارن امكان الاوبجكت فالmemory واكيد كل واحد معمول بـ new يعنى كل واحد مستقبل بذاته

واتمنى ان اكون افدتك

وحد يفيديك اكتر ان شاءا لله

voila

class The extends Thread {
	private String whoami;

	public int delay;

	public The(String b, int d) {
		whoami = b;
		delay = d;
	}

	public void run() {
		try {
			sleep(delay);
		} catch (InterruptedException e) {
		}
		System.out.println("Hi! " + whoami + " " + delay);
	}

}

import javax.swing.JOptionPane;


public class Aa {
	public static void main(String args[]) {
		The t1, t2, t3;
		String result="please try again";
		t1 = new The("Thread1", (int) (Math.random() * 2));//(int) (Math.random() * 10)
		t2 = new The("Thread2", (int) (Math.random() * 2));
		t3 = new The("Thread3",(int) (Math.random() * 2));
		t1.start();
		t2.start();
		t3.start();
		System.out.println(t1);System.out.println(t2);
		if(t1.delay==t2.delay) result = "you win a car!!";
		JOptionPane.showMessageDialog(null, result);

	}
}

اخي Eng.Hamzawy

اشكرك على ردك لكن نفس الناتج

import java.lang.*;

import javax.swing.JOptionPane;

class The extends Thread {

private String whoami;

private int delay;

public The(String b, int d) {

whoami =b;

delay=d;

}

public void run() {

try {

sleep (delay);

}catch (InterruptedException e) {}

System.out.println ("Hi! " + whoami + " " + delay);

}

}

public class Aa {

public static void main (String args[]) {

The t1, t2, t3;

t1=new The ("Thread1", (int)(Math.random() * 0));

t2=new The ("Thread2", (int)(Math.random() * 0));

t3=new The ("Thread3", (int) (Math.random() * 0));

t1.start();

t2.start();

t3.start();

String result;

if (t1.equals(t2)&& t1.equals(t3))

result = "you win a car!!";

else

result = "please try again";

JOptionPane.showMessageDialog( null, result );

}

}

prog_main اخي

اشكرك على الرد

لكن البرنامج فيه ايرور مكان

if(t1.delay==t2.delay)

public class Aa {
		public static void main(String args[]) {
			The t1, t2, t3;
			String result="please try again";
			t1 = new The("Thread1", (int) (Math.random() * 2));//(int) (Math.random() * 10)
			t2 = new The("Thread2", (int) (Math.random() * 2));
			t3 = new The("Thread3",(int) (Math.random() * 2));
			t1.start();
			t2.start();
			t3.start();
			if(t1.delay == t2.delay && t1.delay == t3.delay) result = "you win a car!!";
			JOptionPane.showMessageDialog(null, result);

		}
	}

if(t1.delay == t2.delay && t1.delay == t3.delay) result = "you win a car!!";

فيه ايررور ياريت لو تتاكد منه

برجاء عدم كتابة الكلمات الإنجليزية بحروف عربية
