将二进制数据转换为java中的字符 [英] Converting binary data to characters in java

问题描述

我有一个文件，其内容只有0和1的

I have a file in which its content is only 0's and 1's

我想写一个java程序，将每个8位的0和1转换为char
或换句话说，将文件内容从二进制转换为chars。

I want to write a java program that convert each 8 bit of 0's and 1's to char or in other word, to convert the file content from binary to chars.

为此目的可以使用哪个函数？

Which function can I use for that purpose?

推荐答案

这也是工作

    String s = "0110100001100101011011000110110001101111";
    String str = "";

    for (int i = 0; i < s.length()/8; i++) {

        int a = Integer.parseInt(s.substring(8*i,(i+1)*8),2);
        str += (char)(a);
    }

    System.out.println(str);
