java之比较两个日期大小
最近又用到两个日期大小的比较,因此记录在此,方便以后查阅。
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* 比较日期大小
*/
public class TestDateCompare {
static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); //设置日期格式
public static void main(String[] args) throws ParseException {
Date startDate = sdf.parse("2016-04-15 11:11:11");
Date endDate = sdf.parse("2016-04-16 11:11:11");
if(startDate.before(endDate)){
System.out.println("startDate小于endDate");
}else if(startDate.after(endDate)){
System.out.println("startDate大于endDate");
}else{
System.out.println("startDate等于endDate");
}
if(endDate.after(startDate)){
System.out.println("endDate大于startDate");
}
System.out.println(startDate.compareTo(endDate));
System.out.println(endDate.compareTo(startDate));
System.out.println(endDate.compareTo(endDate));
}
}
运行结果:
startDate小于endDate
endDate大于startDate
