java时间类型转换

获取当前时间

public static Date Time(){
        return new Date();
    }

当前时间转换为“yyyy-MM-dd HH:mm:ss”

public static String Time(){
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		Date time = new Date();
        String endTime = sdf.format(time);
        return endTime;
    }

当前时间转换为long类型毫秒数

public static long Time(){
		Date time = new Date();
        long endTime =time.getTime();
        return endTime;
    }

毫秒数转换为“yyyy-MM-dd HH:mm:ss”

public static String Time(){
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
		Date time = new Date();
		long begin = time.getTime();
       String beginTime = sdf.format(new Date(begin))
        return beginTime ;
    }

毫秒数转换成时间

public static Date Time(){
		Date time = new Date();
		long begin = time.getTime();
        return new Date(begin) ;
    }

“yyyy-MM-dd HH:mm:ss”转换为时间

public static Date Time(){
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
       String beginTime = sdf.format(new Date(begin));
        return sdf.parse(beginTime) ;
    }
