Print Timestamp in Java

You can use the System.currentTimeMillis() method to obtain the current timestamp and use the System.out.println() method to print it. Here is an example code:

public class Main {
    public static void main(String[] args) {
        long timestamp = System.currentTimeMillis();
        System.out.println("当前时间戳:" + timestamp);
    }
}

When you execute this code, it will print out the current timestamp.
