实验MyOD

实验MyOD

编写MyOD.java 用java MyOD XXX实现Linux下od -tx -tc XXX的功能

提交测试代码和运行结果截图，加上学号水印，提交码云代码链接。

代码如下：
（刚开始没有实现-tc的功能，又重新修改了）

import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
public class MyOD {
    public static void dump(InputStream src)
            throws IOException {
        try (InputStream input = src) {
            byte[][] data = new byte[50][1];
            byte[][] transf = new byte[50][1];
            int i = 0, j = 0, num;
            System.out.print("00010: ");
            while (input.read(data[i]) != -1) {
                num = (int) data[i][0];
                System.out.printf("%5s", Integer.toHexString(num));
                i++;
            }
            System.out.print("
00020: ");
            while (j < i) {
                transf[j][0] = (byte) (data[j][0] - 0x30);
                System.out.printf("%5d", transf[j][0]);
                j++;
            }
            System.out.println();
        }
    }

    public static void main(String[] args) {
        FileInputStream fis = null;
        try {
            fis = new FileInputStream("C:\Users\XY\Documents\abc.txt");
            dump(fis);
        } catch (Exception e) {
            System.out.println(e);
        }
    }
}

建立的abc.txt如下：

123456789abc
