This section explains how to get state of a thread in java Thread.
Thread getState() :
Suppose you want to know the state of the thread so for that Java Thread provides Thread.getState() method to get the state of the thread.
public Thread.State getState() : This method
returns the state of the specified thread. its function to monitor the
system state but do not for synchronization control.
Example : This example display the different states of the thread.
class ThreadGetState implements Runnable {
Thread thread;
@Override
public void run() {
Thread.State state = thread.currentThread().getState();
System.out.println(thread.currentThread().getName() + " state is - "
+ state);
}
public static void main(String[] args) {
Thread th = new Thread(new ThreadGetState());
Thread th1 = new Thread(new ThreadGetState());
th.start();
try {
th.sleep(1000);
} catch (Exception e) {
System.out.println(e);
}
Thread.State state = th.getState();
System.out.println(th.getName() + " state is - " + state);
System.out.println(th1.getName() + " state is - " + th1.getState());
th1.start();
try {
th1.join();
} catch (Exception e) {
System.out.println(e);
}
System.out.println(th1.getName() + " state is - " + th1.getState());
}
}
Output :
Thread-0 state is - RUNNABLE Thread-0 state is - TERMINATED Thread-1 state is - NEW Thread-1 state is - RUNNABLE Thread-1 state is - TERMINATED
