Java中的 Locale.Builder setScript() 方法及示例

Java中Java .util.Locale.Builder 类的setScript(String)方法用于将此 Locale.Builder 设置为指定的脚本。这意味着此方法将设置 Locale.Builder 实例的当前脚本以匹配提供的脚本并返回它。如果指定的脚本为 null 或为空，则删除此 LocaleBuilder 的脚本。格式良好的脚本值包括 og 由 ISO 15924 标准定义的 4 个字母的脚本代码。

句法：

public Locale.Builder setScript(String script)

参数：此方法接受脚本作为参数，该参数是要设置为此 Locale.Builder 实例的字符串。

返回值：该方法返回一个Locale.Builder实例，带有这个Locale.Builder的脚本集给指定的脚本。

异常：此方法抛出以下异常：

• IllformedLocaleException : 如果指定的脚本有任何格式错误的字段

方案一：

// Java program to demonstrate
// the above method
  
import java.util.*;
import java.util.Locale.*;
  
public class LocaleBuilderDemo {
    public static void main(String[] args)
    {
  
        // Creating a new Locale.Builder
        Locale.Builder localeBuilder
            = new Builder();
  
        // Displaying Locale.Builder
        System.out.println("LocaleBuilder: "
                           + localeBuilder);
  
        // setting the script of Locale.Builder
        String script = "Gujr";
        System.out.println("Setting the script: "
                           + script);
  
        localeBuilder
            = localeBuilder.setScript(script);
  
        // Displaying Locale.Builder
        System.out.println("Updated LocaleBuilder: "
                           + localeBuilder);
    }
}

输出：

LocaleBuilder: java.util.Locale$Builder@232204a1
Setting the script: Gujr
Updated LocaleBuilder: java.util.Locale$Builder@232204a1

方案二：

// Java program to demonstrate
// the above method
  
import java.util.*;
import java.util.Locale.*;
  
public class LocaleBuilderDemo {
    public static void main(String[] args)
    {
  
        // Creating a new Locale.Builder
        Locale.Builder localeBuilder
            = new Builder();
  
        // Displaying Locale.Builder
        System.out.println("LocaleBuilder: "
                           + localeBuilder);
  
        // setting the script of Locale.Builder
        String script = "asda@vasdev#";
        System.out.println("Setting the script: "
                           + script);
          
        try{
        localeBuilder
            = localeBuilder.setScript(script);
  
        // Displaying Locale.Builder
        System.out.println("Updated LocaleBuilder: "
                           + localeBuilder);
                           }
        catch(Exception e)
        {
            System.out.println(e);
            }
    }
}

输出：

LocaleBuilder: java.util.Locale$Builder@232204a1
Setting the script: asda@vasdev#
java.util.IllformedLocaleException:
 Ill-formed script: asda@vasdev# [at index 0]
