将汉字的字节编码还原成汉字

package utfTest;

import java.io.UnsupportedEncodingException;

public class UTFTest {
    public static void main(String[] args) {
        String s="我";
        try {
            byte[] by = s.getBytes("UTF-8");
            for(byte b : by){
                System.out.println(b);
            }
            byte[] by1 = {-26,-120,-111};
            String s1 = new String(by1,"UTF-8");
            System.out.println(new String(s1));
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }
