JAVA 国际化和数据日期格式化

1、国际化
public class TestResourceBundleMoRen_en extends ListResourceBundle{
	private final Object [][] obj={{"File","File"},
			{"New","New"},{"Open","Open"},{"Save","Save"},{"Exit","Exit"}};
	@Override
	protected Object[][] getContents() {
		return obj;
	}
}
public class TestResourceBundleMoRen_zh_CN extends ListResourceBundle{
	private final Object [][] obj={{"File","文件"},
			{"New","新建"},{"Open","打开"},{"Save","保存"}};
	@Override
	protected Object[][] getContents() {
		return obj;
	}
}
public class TestResourceBundleMoRen  extends ListResourceBundle{
	private final Object [][] obj={{"File","File"},
			{"New","New"},{"Open","Open"},{"Save","Save"},{"Exit","Exit"}};
	@Override
	protected Object[][] getContents() {
		return obj;
	}
}
public class TestBundle {
	public static void main(String[] args) {
		ResourceBundle rb=ResourceBundle.
		getBundle("day621.TestResourceBundleMoRen", Locale.US);
		//参数必须要有包名，改Locale.US就可以实现各个语言切换
		System.out.println(rb.getObject("File"));
		System.out.println(rb.getObject("New"));
		System.out.println(rb.getObject("Open"));
		System.out.println(rb.getObject("Save"));
		System.out.println(rb.getObject("Exit"));
	}
}

2 数据 日期格式化
public class TestLocale {
	public static void main(String[] args) {
		Locale l1=Locale.CHINA;//国家代表语言
		Locale l2=Locale.CHINESE;//语言不代表国家
		System.out.println(l1.getCountry());
		System.out.println(l1.getLanguage());
		System.out.println(l1.getDisplayCountry());
		System.out.println(l1.getDisplayLanguage());
		System.out.println("*************");
		System.out.println(l2.getCountry());//不显示
		System.out.println(l2.getLanguage());
		System.out.println(l2.getDisplayCountry());//不显示
		System.out.println(l2.getDisplayLanguage());
	}
}

public class TestNumberFormat {
	public static void main(String[] args) {
		Locale l1 =Locale.CHINA;
		Locale l2 =Locale.JAPAN;
		Locale l3 =Locale.GERMAN;
		double d =12345.67;
		////////////////数字表示///////////////////////
		NumberFormat nf1=NumberFormat.getInstance(l1);
		NumberFormat nf2=NumberFormat.getInstance(l2);
		NumberFormat nf3=NumberFormat.getInstance(l3);
		System.out.println(nf1.format(d));
		System.out.println(nf2.format(d));
		System.out.println(nf3.format(d));
		/////////////////货币显示/////////////////////////
		NumberFormat nf4=NumberFormat.getCurrencyInstance(l1);
		NumberFormat nf5=NumberFormat.getCurrencyInstance(l2);
		NumberFormat nf6=NumberFormat.getCurrencyInstance(l3);
		System.out.println(nf4.format(d));
		System.out.println(nf5.format(d));
		System.out.println(nf6.format(d));		
	}
}
public class TestDate {
	public static void main(String[] args) {
		Calendar c=new GregorianCalendar(2008,7,8,20,8,8);
		Date d = c.getTime();
		java.sql.Date date =new java.sql.Date(d.getTime());
		System.out.println(date);
		System.out.println(d);
	}
}

public class TestSimpleDate {
	public static void main(String[] args) {
		Calendar c=new GregorianCalendar(2008,7,8,20,8,8);
		Date d = c.getTime();
		String p="yyyy/MM/dd HH:mm:ss";
		SimpleDateFormat sdf =new SimpleDateFormat(p);
		System.out.println(sdf.format(d));
		String s="今天是yyyy年MM月，天气很好";
		SimpleDateFormat sdf2 =new SimpleDateFormat(s);
		System.out.println(sdf2.format(d));
	}
}
