Java的Locale clone() 方法和示例

Java中Locale 类的clone()方法用于简单地创建现有语言环境的克隆或副本。该方法将一种语言环境的内容复制到另一种语言环境。

句法：

Sec_Locale = First_Locale.clone()

参数：该方法不带任何参数。

返回值：此方法返回此语言环境的克隆。

下面的程序说明了 clone() 方法的工作：

方案一：

// Java code to illustrate clone() method
  
import java.util.*;
  
public class Locale_Demo {
    public static void main(String[] args)
    {
  
        // Creating a new locale
        Locale first_locale
            = new Locale("no", "NO", "NY");
  
        // Creating a second locale
        Locale sec_locale;
  
        // Displaying first locale
        System.out.println("First Locale: "
                           + first_locale);
  
        // Cloning first locale to second
        sec_locale
            = (Locale)first_locale.clone();
  
        // Displaying second locale
        System.out.println("Second Locale: "
                           + sec_locale);
    }
}

输出：

First Locale: no_NO_NY
Second Locale: no_NO_NY

方案二：

// Java code to illustrate clone() method
import java.util.*;
  
public class Locale_Demo {
    public static void main(String[] args)
    {
  
        // Creating a new locale
        Locale first_locale
            = new Locale("ga", "IE");
  
        // Creating a second locale
        Locale sec_locale;
  
        // Displaying first locale
        System.out.println("First Locale: "
                           + first_locale);
  
        // Cloning first locale to second
        sec_locale
            = (Locale)first_locale.clone();
  
        // Displaying second locale
        System.out.println("Second Locale: "
                           + sec_locale);
    }
}

输出：

First Locale: ga_IE
Second Locale: ga_IE
