Use boolean value to stop a thread in Java
A thread can be created by implementing the Runnable interface and overriding the run() method. Then a Thread object can be created and the start() method called.
A thread can be stopped using a boolean value in Java. The thread runs while the boolean value stop is false and it stops running when the boolean value stop becomes true.
A program that demonstrates this is given as follows:
Example
class ThreadDemo extends Thread {
public boolean stop = false;
int i = 1;
public void run() {
while (!stop) {
try {
sleep(10000);
} catch (InterruptedException e) {
}
System.out.println(i);
i++;
}
}
}
public class Demo {
public static void main(String[] args) {
ThreadDemo t = new ThreadDemo();
t.start();
try {
Thread.sleep(10000);
} catch (InterruptedException e) {
}
t.stop = true;
System.out.println("The thread is stopped");
}
}Output
1 2 3 4 5 The thread is stopped
