1. Locale 介绍
Locale 表示地区。每一个Locale对象都代表了一个特定的地理、政治和文化地区。
在操作 Date, Calendar等表示日期/时间的对象时，经常会用到；因为不同的区域，时间表示方式都不同。
下面说说Locale对象的3种常用创建方式。
2.三种获取Locale对象的方法、
①:获取默认的Locale
Locale locale = Locale.getDefault()②：直接使用Locale的静态对象，Locale.java中提供了以下静态对象
public static final Locale CANADA
public static final Locale CANADA_FRENCH
public static final Locale CHINA
public static final Locale CHINESE
public static final Locale ENGLISH
public static final Locale FRANCE
public static final Locale FRENCH
public static final Locale GERMAN
public static final Locale GERMANY
public static final Locale ITALIAN
public static final Locale ITALY
public static final Locale JAPAN
public static final Locale JAPANESE
public static final Locale KOREA
public static final Locale KOREAN
public static final Locale PRC
public static final Locale ROOT
public static final Locale SIMPLIFIED_CHINESE
public static final Locale TAIWAN
public static final Locale TRADITIONAL_CHINESE
public static final Locale UK
public static final Locale US</code>例子：下面的Locale对象是对应 “中国(大陆)”的
Locale locale = Locale.SIMPLIFIED_CHINESE③：通过Locale的构造函数创建Locale对象
Locale的构造函数共有3个。如下：
Locale(String language)
Locale(String language, String country)
Locale(String language, String country, String variant)
Locale函数列表
// Locale的构造函数
Locale(String language)
Locale(String language, String country)
Locale(String language, String country, String variant)
Object clone()
boolean equals(Object object)
static Locale[] getAvailableLocales()
String getCountry()
static Locale getDefault()
String getDisplayCountry(Locale locale)
final String getDisplayCountry()
final String getDisplayLanguage()
String getDisplayLanguage(Locale locale)
String getDisplayName(Locale locale)
final String getDisplayName()
final String getDisplayVariant()
String getDisplayVariant(Locale locale)
String getISO3Country()
String getISO3Language()
static String[] getISOCountries()
static String[] getISOLanguages()
String getLanguage()
String getVariant()
synchronized int hashCode()
synchronized static void setDefault(Locale locale)
final String toString()
