Various way to stop a thread - which is the correct way
- by Yan Cheng CHEOK
I had came across different suggestion of stopping a thread. May I know, which is the correct way? Or it depends?
Using Thread Variable http://download.oracle.com/javase/1.4.2/docs/guide/misc/threadPrimitiveDeprecation.html
private volatile Thread blinker;
public void stop() {
blinker = null;
}
public void run() {
Thread thisThread = Thread.currentThread();
while (blinker == thisThread) {
try {
thisThread.sleep(interval);
} catch (InterruptedException e){
}
repaint();
}
}
Using boolean flag
private volatile boolean flag;
public void stop() {
flag = false;
}
public void run() {
while (flag) {
try {
thisThread.sleep(interval);
} catch (InterruptedException e){
}
repaint();
}
}
Using Thread Variable together with interrupt
private volatile Thread blinker;
public void stop() {
blinker.interrupt();
blinker = null;
}
public void run() {
Thread thisThread = Thread.currentThread();
while (!thisThread.isInterrupted() && blinker == thisThread) {
try {
thisThread.sleep(interval);
} catch (InterruptedException e){
}
repaint();
}
}
