setpriority

線程類最終void setPriority(int priority) (Thread Class final void setPriority(int priority))

• This method is available in package java.lang.Thread.setPriority(int priority).

  軟件包java.lang.Thread.setPriority(int priority)中提供了此方法。

• This method is used to set the priority of this thread.

  此方法用于設(shè)置此線程的優(yōu)先級。

• This method is not static so this method is accessible with Thread class object it is not accessible with the class name.

  此方法不是靜態(tài)的，因此該方法可通過Thread類對象訪問，而無法通過類名稱訪問。

• This method is final so we can't override this method in our program.

  此方法是最終方法，因此我們無法在程序中覆蓋此方法。

• The return type of this method is void so it does not return anything.

  此方法的返回類型為void，因此它不返回任何內(nèi)容。

• This method does not raise any exception.

  此方法不會引發(fā)任何異常。

• We need to notice that if we don't assign any priority explicitly the default priority of this thread is 5.

  我們需要注意的是，如果我們未明確分配任何優(yōu)先級，則此線程的默認(rèn)優(yōu)先級為5。

• Priority range will lie between 1 and 10 and 1 is the min_priority and 10 is the max_priority of a thread.

  優(yōu)先級范圍在1到10之間，其中1是線程的min_priority ，而10是max_priority 。

Syntax:

句法：

final void setPriority(int priority){}

Parameter(s):

參數(shù)：

We pass only one object as a parameter in the method of the Thread and the parameter is the priority of this thread too.

我們僅在Thread方法中傳遞一個(gè)對象作為參數(shù)，該參數(shù)也是該線程的優(yōu)先級。

Return value:

返回值：

The return type of this method is void, it does not return anything.

此方法的返回類型為void ，它不返回任何內(nèi)容。

Java程序演示setPriority()方法的示例 (Java program to demonstrate example of setPriority() 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 SetThreadPriority extends Thread {// Override run() of Thread classpublic void run() {System.out.println("Thread Name : " + Thread.currentThread().getName());System.out.println("Current thread priority is : " + Thread.currentThread().getPriority());// By using setPriority() method is used to change // the priority of this threadThread.currentThread().setPriority(6);System.out.println("New thread priority is : " + Thread.currentThread().getPriority());}public static void main(String[] args) {// Creating an object of SetThreadPriority classSetThreadPriority st_priority = new SetThreadPriority();// We are setting the name of the thread GetThreadPriorityst_priority.setName("SetThreadPriority");// Calling start() method with SetThreadPriority class // object of Thread classst_priority.start();} }
