Java面试题_获取系统时间_2

一、代码（希望一直打印当前的时间）

package DR3;

import java.text.SimpleDateFormat;
import java.util.Date;

public class TestSleep1 {
    public static void main(String[] args) {
while(true){
        //System.out.println(i);
        try {
        Thread.sleep(1000);
        } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }
        //System.out.println(new Date());
        Date now =new Date();
        SimpleDateFormat sdf= new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        String str =sdf.format(now);
        System.out.println(str);
        }
    }
}

二、输出结果（执行程序后，想让结束，截图右下角stop）

"C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.3\jbr\bin\java.exe" "-javaagent:C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.3\lib\idea_rt.jar=59424:C:\Program Files\JetBrains\IntelliJ IDEA 2019.3.3\bin" -Dfile.encoding=UTF-8 -classpath D:\sxxh\qnxd\DRlianxi\out\production\DRlianxi DR3.TestSleep1
