Java Calendar set()用法及代码示例

Calendar类中的set(int calndr_field，int new_val)方法用于将calndr_field值设置为new_val。此日历的旧字段将替换为新字段。

用法:

public void set(int calndr_field, int new_val)

参数：该方法有两个参数：

calndr_field：这是“日历”类型，是指要更改的日历字段。
new_val：这是指要替换的新值。

返回值：该方法不返回任何值。

以下示例程序旨在说明Calendar类的set()方法的用法：
示例1:

// Java code to illustrate 
// set() method 
  
import java.util.*; 
public class Calendar_Demo { 
    public static void main(String args[]) 
    { 
  
        // Creating a calendar 
        Calendar calndr = Calendar.getInstance(); 
  
        // Displaying the month 
        System.out.println("The Current Month is: "
                           + calndr.get( 
                                 Calendar.MONTH)); 
  
        // Replacing with a new value 
        calndr.set(Calendar.MONTH, 11); 
  
        // Displaying the modified result 
        System.out.println("Altered Month is: "
                           + calndr.get( 
                                 Calendar.MONTH)); 
    } 
}

输出：

The Current Month is: 1
Altered Month is: 11

示例2:

// Java code to illustrate 
// set() method 
  
import java.util.*; 
public class Calendar_Demo { 
    public static void main(String args[]) 
    { 
  
        // Creating a calendar 
        Calendar calndr = Calendar.getInstance(); 
  
        // Displaying the Year 
        System.out.println("The Current year is: "
                           + calndr.get( 
                                 Calendar.YEAR)); 
  
        // Replacing with a new value 
        calndr.set(Calendar.YEAR, 1996); 
  
        // Displaying the modified result 
        System.out.println("Altered year is: "
                           + calndr.get( 
                                 Calendar.YEAR)); 
    } 
}

输出：

The Current year is: 2019
Altered year is: 1996
