Get Current Timestamp in Java

In Java, you can use the System.currentTimeMillis() method to get the current timestamp, which is the number of milliseconds since January 1, 1970, 00:00:00 GMT. Here is an example code:

long currentTimeMillis = System.currentTimeMillis();
System.out.println("当前时间戳：" + currentTimeMillis);

Running the above code will output similar content to the following:

当前时间戳：1644812606246
