2.怎样去用提取出的系统时间去跟年月日做比较(例:1985-01-01 09:12:01怎么样去判断他是否在1984-01-01至1985-01-04之间)

- Java code
package test;import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;public class panel { public static void main(String[] args) throws ParseException { SimpleDateFormat sm = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println(sm.format(new Date(System.currentTimeMillis()))); Date date = sm.parse("1985-01-01 09:12:01"); Date currentDate = new Date(System.currentTimeMillis()); if(date.compareTo(currentDate)==-1) { System.out.println("date < currentDate"); }else if(date.compareTo(currentDate)==0) { System.out.println("date = currentDate"); }else if(date.compareTo(currentDate)==1) { System.out.println("date > currentDate"); } }}
