中文转换成UTF-8格式的java代码

从网上找的，加入了屏幕读写功能。实现从中文到UTF-8（两种格式的转换）

-------------------------------------------

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

class TransformToChinese

{

public static String GBK2Unicode(String str){

StringBuffer result = new StringBuffer();

for (int i = 0; i < str.length(); i++){

char chr1 = (char)str.charAt(i);

if(!isNeedConvert(chr1)){

result.append(chr1);

continue;

}

result.append("\\u" + Integer.toHexString((int)chr1));

}

return result.toString();

}

public static boolean isNeedConvert(char para){

return ((para&(0x00FF))!=para);

}

public static String GBK2Unicode2(String str){

StringBuffer result = new StringBuffer();

for (int i = 0; i < str.length(); i++){

char chr1 = (char)str.charAt(i);

result.append("&#" + Integer.toString((int)chr1)+ ";");

}

return result.toString();

}

public static void main(String[] args) throws IOException{

BufferedReader br=new BufferedReader(new InputStreamReader(System.in));

String str=br.readLine();

System.out.println(GBK2Unicode(str));

System.out.println(GBK2Unicode2(str));

}

}
