补交 20155202 蓝墨云班课 编写MyCP.java 实现类似Linux下cp XXX1 XXX2的功能

蓝墨云班课 编写MyCP.java

要求:

编写MyCP.java 实现类似Linux下cp XXX1 XXX2的功能,要求MyCP支持两个参数:

  • java MyCP -tx XXX1.txt XXX2.bin 用来把文本文件(内容为十进制数字)转化为二进制文件
  • java MyCP -xt XXX1.bin XXX2.txt 用来二进制文件把转化为文本文件(内容为十进制数字)

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。

代码托管

  • 我将主函数定义为MYDC;
  • 然后通过调用输入文档,将其中的数转2进制到输出文档中,类代码如下:
public static void dumpToTwo(InputStream src, OutputStream dest)
            throws IOException {
        try (InputStream input = src; OutputStream output = dest) {
            byte[] data = new byte[1];
            int length;
            while ((length = input.read(data)) != -1) {
                String str = Integer.toBinaryString((data[0]&0xFF)+0x100).substring(1);
                data[0] = Byte.parseByte(str);
                output.write(data, 0, length);
            }
        }
    }
  • 调用输入文档,将其中的数转十进制到输出文档中,类代码如下:
public static void dumpToTen(InputStream src, OutputStream dest)
            throws IOException {
        try (InputStream input = src; OutputStream output = dest) {
            byte[] data = new byte[1];
            int length;
            while ((length = input.read(data)) != -1) {
                data[0] = Byte.parseByte(String.valueOf(data[0]),10);
                output.write(data, 0, length);
            }
        }
    }
  • 这是我的完整代码:
/**

import java.io.*;

class MyCP{
    public static void dumpToTwo(InputStream src, OutputStream dest)
            throws IOException {
        try (InputStream input = src; OutputStream output = dest) {
            byte[] data = new byte[1];
            int length;
            while ((length = input.read(data)) != -1) {
                String str = Integer.toBinaryString((data[0]&0xFF)+0x100).substring(1);
                data[0] = Byte.parseByte(str);
                output.write(data, 0, length);
            }
        }
    }
    public static void dumpToTen(InputStream src, OutputStream dest)
            throws IOException {
        try (InputStream input = src; OutputStream output = dest) {
            byte[] data = new byte[1];
            int length;
            while ((length = input.read(data)) != -1) {
                data[0] = Byte.parseByte(String.valueOf(data[0]),10);
                output.write(data, 0, length);
            }
        }
    }
    public static void main(String[] args) {
        FileInputStream fis = null;
        FileOutputStream fos = null;
        try {
            fis = new FileInputStream("/home/zx/代码托管/shuru.java");
            fos = new FileOutputStream("/home/zx/代码托管/shuchu.java");
            dumpToTen(fis, fos);
        }catch(Exception e) {
            System.out.println(e);
        }
    }

}
