Java TimeUnit sleep()用法及代碼示例

TimeUnit類的sleep()方法用於使用此時間單位執行Thread.sleep。這是一種方便的方法，可以將時間參數睡眠為Thread.sleep方法所需的形式。

用法:

public void sleep(long timeout)
           throws InterruptedException

參數：此方法接受強製參數超時，這是最短的睡眠時間。如果小於或等於零，則根本不睡覺。

返回值：此方法不返回任何內容。

異常：如果在睡眠期間被中斷，則此方法將引發InterruptedException。

以下示例程序旨在說明TimeUnit sleep()方法的實現：

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"); 
        } 
    } 
}

輸出：

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"); 
        } 
    } 
}

輸出：

Going to sleep for 10 seconds
Slept for 10 seconds
