用法:
public Locale.Builder setLanguage(String language)
参数:此方法接受语言作为参数,该参数是要设置为此Locale.Builder实例的String。
返回值:此方法返回Locale.Builder实例,并将此Locale.Builder的语言设置为指定的语言。
异常:此方法引发以下异常:
- IllformedLocaleException:如果指定的语言有任何格式错误的字段
程序1:
// 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 language of Locale.Builder
String language = "FRENCH";
System.out.println("Setting the language:"
+ language);
localeBuilder
= localeBuilder.setLanguage(language);
// Displaying Locale.Builder
System.out.println("Updated LocaleBuilder:"
+ localeBuilder);
}
}
输出:
LocaleBuilder:java.util.Locale$Builder@232204a1 Setting the language:FRENCH Updated LocaleBuilder:java.util.Locale$Builder@232204a1
程序2:
// 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 language of Locale.Builder
String language = "asdasf@!vsd#";
System.out.println("Setting the language:"
+ language);
try{
localeBuilder
= localeBuilder.setLanguage(language);
// 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 language:asdasf@!vsd# java.util.IllformedLocaleException:Ill-formed language:asdasf@!vsd# [at index 0]
