this.getstate

線程類(lèi)Thread.State getState() (Thread Class Thread.State getState())

• This method is available in package java.lang.Thread.getState().

  軟件包java.lang.Thread.getState()中提供了此方法。

• This method is used to return the state of this thread.

  此方法用于返回此線程的狀態(tài)。

• When we execute a thread so there are various states for normal execution of the thread [States of the Thread like, start, ready, running, waiting, blocked, terminate].

  當(dāng)我們執(zhí)行一個(gè)線程時(shí)，有多種狀態(tài)可以正常執(zhí)行該線程[線程的狀態(tài)，如啟動(dòng)，就緒，運(yùn)行，等待，阻塞，終止]。

• This method is not final so we can override this method in child class.

  此方法不是最終方法，因此我們可以在子類(lèi)中重寫(xiě)此方法。

• The return type of this method is Thread.State so it returns the state of this thread

  此方法的返回類(lèi)型為T(mén)hread.State，因此它返回此線程的狀態(tài)。

• This method does not raise any exception.

  此方法不會(huì)引發(fā)任何異常。

Syntax:

句法：

Thread.State getState(){}

Parameter(s):

參數(shù)：

We don't pass any object as a parameter in the method of the Thread.

我們不會(huì)在Thread方法中將任何對(duì)象作為參數(shù)傳遞。

Return value:

返回值：

The return type of this method is Thread.State, it returns the state of this thread.

該方法的返回類(lèi)型為T(mén)hread.State ，它返回此線程的狀態(tài)。

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 classpublic void run() {// By using getState() method is used to return // the state of this threadSystem.out.println("The state of this thread is : " + Thread.currentThread().getState());/* This is another way of writing the above statementThread.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 classGetThreadState gt_state = new GetThreadState();// We are setting the name of the thread GetThreadStategt_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());} }
