When Java runs a for loop, it is hoped that each loop can pause for a period of time.

Just use the sleep method:

for (int i = 0; i < 10; i++) {
    
    
    try {
    
    
        System.out.println("i:" + i + " time:" + getTme());
        Thread.sleep(10 * 1000); // 暂停10秒
    } catch (InterruptedException e) {
    
    
        e.printStackTrace();
    }
}

Then define the time format:

Long current_time = System.currentTimeMillis();
SimpleDateFormat formate = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
String formateTime = formate.format(current_time);

After running, you can see the output:

i:0 time:15:35:06
i:1 time:15:35:16
i:2 time:15:35:26
i:3 time:15:35:36
i:4 time:15:35:46

Pause for 10 seconds successfully.
