Java中Date类的使用

package Date;

import java.util.Date;

public class DateDemo {
public static void main(String[] args) throws InterruptedException {
Date date1=new Date();
System.out.println(date1.toString());
Thread.sleep(1000);
Date date2=new Date();
System.out.println(date2.toString());
System.out.println(date1.before(date2));
System.out.println(date2.getTime()-date1.getTime());
}

}
