Java TimeUnit sleep()用法及代码示例

TimeUnit类的sleep()方法用于使用此时间单位执行Thread.sleep。这是一种方便的方法，可以将时间参数睡眠为Thread.sleep方法所需的形式。

用法:

public void sleep(long timeout)
           throws InterruptedException

参数：此方法接受强制参数超时，这是最短的睡眠时间。如果小于或等于零，则根本不睡觉。

返回值：此方法不返回任何内容。

异常：如果在睡眠期间被中断，则此方法将引发InterruptedException。

以下示例程序旨在说明TimeUnit sleep()方法的实现：

示例1:

// Java program to demonstrate 
// sleep() method of TimeUnit Class 
  
import java.util.concurrent.*; 
  
class GFG { 
    public static void main(String args[]) 
    { 
        // Get time to sleep 
        long timeToSleep = 0L; 
  
        // Create a TimeUnit object 
        TimeUnit time = TimeUnit.SECONDS; 
  
        try { 
  
            System.out.println("Going to sleep for "
                               + timeToSleep 
                               + " seconds"); 
  
            // using sleep() method 
            time.sleep(timeToSleep); 
  
            System.out.println("Slept for "
                               + timeToSleep 
                               + " seconds"); 
        } 
  
        catch (InterruptedException e) { 
            System.out.println("Interrupted "
                               + "while Sleeping"); 
        } 
    } 
}

输出：

Going to sleep for 0 seconds
Slept for 0 seconds

示例2:

// Java program to demonstrate 
// sleep() method of TimeUnit Class 
  
import java.util.concurrent.*; 
  
class GFG { 
    public static void main(String args[]) 
    { 
        // Get time to sleep 
        long timeToSleep = 10L; 
  
        // Create a TimeUnit object 
        TimeUnit time = TimeUnit.SECONDS; 
  
        try { 
  
            System.out.println("Going to sleep for "
                               + timeToSleep 
                               + " seconds"); 
  
            // using sleep() method 
            time.sleep(timeToSleep); 
  
            System.out.println("Slept for "
                               + timeToSleep 
                               + " seconds"); 
        } 
  
        catch (InterruptedException e) { 
            System.out.println("Interrupted "
                               + "while Sleeping"); 
        } 
    } 
}

输出：

Going to sleep for 10 seconds
Slept for 10 seconds
