这是根据你的要求编写的代码。
import java.util.Calendar
import java.sql.Date
public class TestAA {
/**
* @param args
*/
public static void main(String[] args) {
Calendar cld = Calendar.getInstance()
Date date = new java.sql.Date(1319534374312l)
cld.setTime(date)
/**
* 注：在jdk1.6以后下列方法都已过时
* date.getYear()
* date.getMonth()
* date.getDay()
*/
System.out.println("日期为："+date.toString())
//方法一
System.out.println("年份："+cld.get(Calendar.YEAR))
System.out.println("月份："+(cld.get(Calendar.MONTH)+1))
System.out.println("日："+cld.get(Calendar.DAY_OF_MONTH))
//方法er
System.out.println("年份："+date.toString().split("-")[0])
System.out.println("月份："+date.toString().split("-")[1])
System.out.println("日："+date.toString().split("-")[2])
}
}
你看看，应该没问题。
//得到long类型当前时间
long l = System.currentTimeMillis()
//new日期对
Date date = new Date(l)
//转换提日期输出格式
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-
dd HH:mm:ss")System.out.println(dateFormat.format(date))
