Java multithreaded application loop output ABC
There are three thread IDs: A, B, and C. Please use multi-line programming to implement it. Print ABCABC 10 times on the screen.
Please add the following code
public class Test {
public static void main(String[] args) {
MajusculeABC maj = new MajusculeABC();
Thread t_a = new Thread(new Thread_ABC(maj , 'A'));
Thread t_b = new Thread(new Thread_ABC(maj , 'B'));
Thread t_c = new Thread(new Thread_ABC(maj , 'C'));
t_a.start();
t_b.start();
t_c.start();
}
}
class MajusculeABC {
Please add code
}
class Thread_ABC implements Runnable {
Please add code
}The answer is as follows
public class ThreadTest {
public static void main(String[] args) throws InterruptedException {
MajusculeABC maj = new MajusculeABC();
Thread t_a = new Thread(new Thread_ABC(maj , 'A'));
Thread t_b = new Thread(new Thread_ABC(maj , 'B'));
Thread t_c = new Thread(new Thread_ABC(maj , 'C'));
t_a.start();
t_b.start();
t_c.start();
}
private static class MajusculeABC {
// Please add the code public MajusculeABC() {
}
private int a = 1;
private synchronized void print(int index, char s) throws InterruptedException {
do {
if (s == 'A' && a == 1) {
a++;
(index+"---" + s);
notifyAll();
break;
} else if (s == 'B' && a == 2) {
a++;
(index+"---" + s);
notifyAll();
break;
} else if (s == 'C' && a == 3) {
a = 1;
(index+"---" + s);
notifyAll();
break;
} else {
wait();
}
} while (true);
}
}
private static class Thread_ABC implements Runnable {
private char s;
private MajusculeABC majusculeABC;
// Please add the code public Thread_ABC(MajusculeABC majusculeABC, char s) {
= majusculeABC;
= s;
}
@Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
(i, s);
} catch (InterruptedException e) {
();
}
}
}
}
}The output is as follows:
0---A
0---B
0---C
1---A
1---B
1---C
2---A
2---B
2---C
3---A
3---B
3---C
4---A
4---B
4---C
5---A
5---B
5---C
6---A
6---B
6---C
7---A
7---B
7---C
8---A
8---B
