java.text.Collator类的getInstance(Locale)方法用于获取具有所需语言环境的新整理对象。
用法:
public static Collator getInstance(Locale desiredLocale)
参数：此方法采用必须为其创建整理对象的期望语言环境。
返回值：它提供具有所需语言环境的新整理者对象。
下面是说明getInstance()方法的示例：
范例1：
// Java program to demonstrate
// getInstance() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing new simple rule
String simple = "< a< b< c< d";
// Creating and initializing
// new RuleBasedCollator Object
RuleBasedCollator col_1
= new RuleBasedCollator(simple);
// Creating and initializing Collator
// Object with Locale.UK
// using getInstance() method
Collator col_2
= Collator.getInstance(Locale.UK);
// display result
if (col_1.equals(col_2))
System.out.println(
col_1
+ " is equal to "
+ col_2);
else
System.out.println(
col_1
+ " is not equal to "
+ col_2);
}
catch (ClassCastException e) {
System.out.println("Exception thrown:" + e);
}
catch (ParseException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出：
java.text.RuleBasedCollator@5eb2e1c2 is not equal to java.text.RuleBasedCollator@289747d6
范例2：
// Java program to demonstrate
// getInstance() method
import java.text.*;
import java.util.*;
import java.io.*;
public class GFG {
public static void main(String[] argv)
{
try {
// Creating and initializing Collator Object
// with Locale.UK
// using getInstance() method
Collator col_1 = Collator.getInstance(Locale.UK);
// Creating and initializing Collator Object
// with Locale.US
// using getInstance() method
Collator col_2 = Collator.getInstance(Locale.US);
// display result
if (col_1.equals(col_2))
System.out.println(
col_1
+ " is equal to "
+ col_2);
else
System.out.println(
col_1
+ " is not equal to "
+ col_2);
}
catch (ClassCastException e) {
System.out.println("Exception thrown:" + e);
}
}
}
输出：
java.text.RuleBasedCollator@289747d6 is equal to java.text.RuleBasedCollator@289747d6
