极客教程Java 日历 getTime()方法及示例
Calendar类中的 getTime() 方法用于返回一个类似于Date的对象，该对象由这个Calendar的时间值代表。
语法：
public final Date getTime()
Java
参数： 该方法不接受任何参数。
返回值： 该方法返回日期，由该日历表示。
以下程序说明了日历类的getTime()方法的工作：
例子1：
// Java code to illustrate
// getTime() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
throws InterruptedException
{
// Creating a calendar
Calendar calndr1
= Calendar.getInstance();
// Displaying the current time
System.out.println("The Current"
+ " Time is: "
+ calndr1.getTime());
// Adding few delay
Thread.sleep(10000);
// Creating another calendar
Calendar calndr2 = Calendar.getInstance();
// Displaying the upcoming time
Date dt = calndr2.getTime();
System.out.println("The upcoming"
+ " time is: " + dt);
}
}
Java
输出
The Current Time is: Wed Feb 20 14:40:37 UTC 2019
The upcoming time is: Wed Feb 20 14:40:47 UTC 2019
Java
例2：
// Java code to illustrate
// getTime() method
import java.util.*;
public class Calendar_Demo {
public static void main(String args[])
throws InterruptedException
{
// Creating a calendar
Calendar calndr1
= Calendar.getInstance();
// Displaying the current time
System.out.println("The Current"
+ " Time is: "
+ calndr1.getTime());
// Adding few delay
Thread.sleep(5000);
// Creating another calendar
Calendar calndr2 = Calendar.getInstance();
// Displaying the upcoming time
Date dt = calndr2.getTime();
System.out.println("The upcoming"
+ " time is: " + dt);
}
}
Java
输出
The Current Time is: Wed Feb 20 14:40:50 UTC 2019
The upcoming time is: Wed Feb 20 14:40:55 UTC 2019
