关于CharSet

Charset用于创建解码器和编码器以及检索与 charset 关联的各种名称的方法。

以下是获得系统的获得系统的从charSet名称到charset对象的映射

public class CharsetTest {
   
    /** Creates a new instance of CharsetTest */
    public CharsetTest() {
    }
    public String getAllCharSet(){
        StringBuffer buf  = new StringBuffer();
        SortedMap charsets = Charset.availableCharsets();//构造从规范 charset 名称到 charset 对象的有序映射
        Set names = charsets.keySet();
        int mainCounter = 0;
        Iterator nameTte =names.iterator();
        while(nameTte.hasNext()){
            String name = (String)nameTte.next();
            Charset charset = (Charset)charsets.get(name);
            buf.append(++mainCounter).append(";").append(charset).append("\n");
            Set aliases = charset.aliases();
            int subCounter =1;
            Iterator aliasIte =aliases.iterator();
            while(aliasIte.hasNext()){
                buf.append("\t").append(mainCounter).append(".");
                buf.append(subCounter++).append(";");
                buf.append(aliasIte.next()).append("\n");
            }
            buf.append("\n");
        }
        return buf.toString();
       
    }
    public static void main(String[] args) {
        CharsetTest ct = new CharsetTest();
        System.out.println(ct.getAllCharSet());
    }
}
