在Java中使用bytearrayoutputstream导出中文时出错

Question

这些是Java代码。它只是“ ByteArrayOutputStream”的小测试，当我根据教学视频进行练习时，编译通过，执行结果出现乱码，不知道哪里出错了

package com.xiaoyin.otherIO;

import java.io.ByteArrayOutputStream;
import java.io.FileInputStream;
import java.io.IOException;

public class Test {
    public static void main(String[] args) throws IOException {
    // Create a buffer output stream object to write data
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    // Create input stream objects, realize data reading, connect a txt text, which has several in both English and Chinese
    FileInputStream fis = new FileInputStream("d.txt");
    // Reading data
    int b = -1;
    while ((b = fis.read()) != -1) {
        // Store all the data you read in memory
        baos.write(b);
    }``
    // Remove all data from the buffer and convert it to a byte array
    byte[] arr = baos.toByteArray();
    System.out.println(new String(arr));
    // Turn off the input stream
    fis.close();
    }
}
