看看这篇关于如何正确做到这一点的简短文章。

本质上:捕获InterruptedException。记住，您必须添加这个捕获块。这篇文章对此作了进一步的解释。

public static void main(String[] args) throws InterruptedException {
  //type code


  short z=1000;
  Thread.sleep(z);/*will provide 1 second delay. alter data type of z or value of z for longer delays required */

  //type code
}

eg:-

class TypeCasting {

  public static void main(String[] args) throws InterruptedException {
    short f = 1;
    int a = 123687889;
    short b = 2;
    long c = 4567;
    long d=45;
    short z=1000;
    System.out.println("Value of a,b and c are\n" + a + "\n" + b + "\n" + c + "respectively");
    c = a;
    b = (short) c;
    System.out.println("Typecasting...........");
    Thread.sleep(z);
    System.out.println("Value of B after Typecasting" + b);
    System.out.println("Value of A is" + a);


  }
}

放置你的线程。睡在一个尝试捕捉块

try {
    //thread to sleep for the specified number of milliseconds
    Thread.sleep(100);
} catch ( java.lang.InterruptedException ie) {
    System.out.println(ie);
}

使用下面的编码结构来处理异常

try {
  Thread.sleep(1000);
} catch (InterruptedException ie) {
    //Handle exception
}

我给Java程序添加延迟的方法。

public void pause1(long sleeptime) {
    try {
        Thread.sleep(sleeptime);
    } catch (InterruptedException ex) {
        //ToCatchOrNot
    }
}

public void pause2(long sleeptime) {
    Object obj = new Object();
    if (sleeptime > 0) {
        synchronized (obj) {
            try {
                obj.wait(sleeptime);
            } catch (InterruptedException ex) {
                //ToCatchOrNot
            }
        }
    }
}
public void pause3(long sleeptime) {
    expectedtime = System.currentTimeMillis() + sleeptime;
    while (System.currentTimeMillis() < expectedtime) {
        //Empty Loop   
    }
}

这是针对顺序延迟，但对于循环延迟，请参考Java延迟/等待。

试试这个:

try{

    Thread.sleep(100);
}catch(Exception e)
{
   System.out.println("Exception caught");
}
