在java中实现fread (readInt)

import java.io.*;

public class FileReaderExample {
    public static void main(String[] args) {
        String filePath = "path/to/file"; // 文件路径

        try {
            FileInputStream fileInputStream = new FileInputStream(filePath);
            DataInputStream dataInputStream = new DataInputStream(fileInputStream);

            int intValue = dataInputStream.readInt(); // 读取整数

            System.out.println("Read integer value: " + intValue);

            dataInputStream.close();
            fileInputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
