Java程序演示getState()方法的示例 (Java program to demonstrate example of getState() method)

/*  We will use Thread class methods so we are importing 
the package but it is not mandate because 
it is imported by default
*/
import java.lang.Thread;
class GetThreadState extends Thread {
// Override run() of Thread class
public void run() {
// By using getState() method is used to return 
// the state of this thread
System.out.println("The state of this thread is : " + Thread.currentThread().getState());
/* This is another way of writing the above statement
Thread.State th_state = Thread.currentThread().getState();
System.out.println("The state of this thread is : "+th_state);*/
}
public static void main(String[] args) {
// Creating an object of GetThreadState class
GetThreadState gt_state = new GetThreadState();
// We are setting the name of the thread GetThreadState
gt_state.setName("GetThreadState");
// Calling start() method with GetThreadState class 
// object of Thread class/
gt_state.start();
// By using getName() method to return the name of this 
// thread [GetThreadState]
System.out.println("The name of this thread is " + " " + gt_state.getName());
}
}
