从同一个FileInputStream中读取字符串和二进制文件

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

public class ReadFile {
    public static void main(String[] args) throws Exception {
        FileInputStream fis = new FileInputStream("example.txt");
        InputStreamReader isr = new InputStreamReader(fis);
        BufferedReader br = new BufferedReader(isr);

        // 读取字符串
        String line;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }

        // 读取二进制文件
        byte[] buffer = new byte[1024];
        int bytesRead;
        while ((bytesRead = fis.read(buffer)) != -1) {
            // 处理字节流
        }

        // 关闭资源
        br.close();
        fis.close();
    }
}
