Java 中的格式化程序 locale()方法，示例
原文:https://www . geesforgeks . org/formatter-locale-method-in-Java-with-examples/
locale() 方法是 java.util.Formatter 的内置方法，它返回一个区域设置。该区域设置由格式化程序构造设置。具有区域设置参数的此对象的 format 方法不会更改此值。
语法 :
public Locale locale()
参数:该功能不接受参数。
返回值:如果没有应用本地化，函数返回空值，否则返回一个已经初始化为格式化程序的区域设置。
异常:如果在函数调用之前格式化程序已经关闭，函数抛出格式化程序关闭异常。
下面是上述功能的实现:
程序 1:
// Java program to implement
// the above function
import java.util.Formatter;
import java.util.Locale;
public class Main {
public static void main(String[] args)
{
// Get the string Buffer
StringBuffer buffer
= new StringBuffer();
// Object creation
Formatter frmt
= new Formatter(buffer,
Locale.CANADA);
// Format a new string
String name = "My name is Gopal Dave";
frmt.format("What is your name? \n%s !",
name);
// Print the Formatted string
System.out.println(frmt);
// Prints the format that has been set
// Initially to the formatter
System.out.println("Locale: "
+ frmt.locale());
}
}
输出:
What is your name?
My name is Gopal Dave !
Locale: en_CA
程序二:
// Java program to implement
// the above function
import java.util.Formatter;
import java.util.Locale;
public class Main {
public static void main(String[] args)
{
try {
// Get the string Buffer
StringBuffer buffer
= new StringBuffer();
// Object creation
Formatter frmt
= new Formatter(buffer,
Locale.CANADA);
// Format a new string
String name = "My name is Gopal Dave";
frmt.format("What is your name? \n%s !",
name);
// Print the Formatted string
System.out.println(frmt);
// Formatter closed
frmt.close();
// Prints the format that has been set
// Initially to the formatter
System.out.println("Locale: "
+ frmt.locale());
}
catch (Exception e) {
System.out.println("Exception is: "
+ e);
}
}
}
输出:
What is your name?
My name is Gopal Dave !
Exception is: java.util.FormatterClosedException
