I saw How to wait current thread execution and execute another thread completedly? on StackOverflow, and I answered it there, but would like more eyes on the code I posted.
The requirement is to pause one thread whilst a different thread is running.
Could you please review and comment on this implementation?
public class App {
public static void main(String[] args) {
Thread1 thread1 = new Thread1();
Thread2 thread2 = new Thread2();
try {
thread1.start();
Thread.sleep(500);
synchronized (thread1) {
thread1.waiting = true;
thread2.start();
thread2.join();
thread1.waiting = false;
thread1.notify();
}
} catch (Exception e) {
//TODO actually handle exception
}
}
}
Class Thread1.java
public class Thread1 extends Thread {
boolean waiting = false;
public void run() {
testFun1();
}
public void testFun1() {
for (int i = 1; i < 10; i++) {
synchronized (this) {
while (waiting) {
try {
wait();
} catch (Exception e) {
//TODO Handle exception
}
}
}
try {
Thread.sleep(100);
System.out.println("From testFun1() = " + i);
} catch (Exception e) {
//TODO Handle exception
}
}
}
}
Class Thread2.java
public class Thread2 extends Thread {
public void run() {
testFun2();
}
public void testFun2() {
try {
for (int i = 20; i <= 25; i++) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
//catch
}
System.out.println("From testFun2() = " + i);
}
} catch (Exception e) {
//TODO do something
}
}
}
Output:
