不使用java.lang.String将以字节数组编码的字符串转换为字符数组

import java.nio.charset.Charset;
import java.nio.charset.CharsetDecoder;
import java.nio.ByteBuffer;

public class ByteArrayToString {
    public static void main(String[] args) {
        byte[] byteArray = {97, 98, 99, 100}; // 示例字节数组

        Charset charset = Charset.forName("UTF-8"); // 字节数组的编码方式
        CharsetDecoder decoder = charset.newDecoder();

        try {
            ByteBuffer byteBuffer = ByteBuffer.wrap(byteArray);
            char[] charArray = decoder.decode(byteBuffer).array();
            System.out.println(charArray);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

import java.io.ByteArrayInputStream;
import java.io.InputStreamReader;
import java.io.BufferedReader;

public class ByteArrayToString {
    public static void main(String[] args) {
        byte[] byteArray = {97, 98, 99, 100}; // 示例字节数组

        try {
            ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArray);
            InputStreamReader inputStreamReader = new InputStreamReader(byteArrayInputStream, "UTF-8"); // 字节数组的编码方式
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

            char[] charArray = new char[byteArray.length];
            bufferedReader.read(charArray, 0, byteArray.length);
            System.out.println(charArray);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
