将字符串转码

字符转码原理是根据String的方法：getBytes(String characterset)和String的构造（unicode的bytes ，输出编码名称）即：new String(Bytes[] args,String characterset)

使用时方法如下：str =  new String(src.getBytes(srcCoding),destCoding);

也可以写成方法如下：

src要转码的字符串，srcCoding原码，要转换成的编码，如：【

public static String transcodingString(String str){
return transcodingString(str,"ISO8859-1","UTF-8");
}】

public static String transcodingString(String str,String srcCoding,String destCoding){
String string="";
try {
string= new String(src.getBytes(srcCoding),destCoding);
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return string;
}
