public static String UnicodeToChinese(String s){
try{
if(s==null||s.equals("")) return "";
String newstring=null;
newstring=new String(s.getBytes("ISO8859_1"),"gb2312");
return newstring;
}
catch(UnsupportedEncodingException e)
{
return s;
}
}

public static String ChineseToUnicode(String s){
try{
if(s==null||s.equals("")) return "";
String newstring=null;
newstring=new String(s.getBytes("gb2312"),"ISO8859_1");

public String getStr(String str)//中文处理
{
try
{
String temp_p=str;
byte[] temp_t=temp_p.getBytes("ISO8859-1");
String temp=new String(temp_t);
return temp;
}
catch(Exception e)
{
e.printStackTrace() ;
}
return "null";

楼上两兄弟的都不好使。
在j2me中找不到gb2312的，我想找转化的原码

不可能得到字符串的编码方式的，只有在知道编码的情况下才能转化为其他的编码。否则都是按系统默认的编码方式读取。Top
