Java中的ASCii到二进制转换程序

问题描述

我目前正在从事将ASCii字符串文本转换为二进制数字的项目，但是我遇到了几个问题.首先，我想确切地知道如何从字符串中提取一位数字并打印出二进制后代，其次，应用此方法的最佳方法是什么?谢谢

I am currently working on a project that would convert ASCii string text into Binary digits, but I've come upon several issues. First off, I would like to know exactly how can I take single digit from a String and print out it's Binary offspring, secondly What would be the best method of applying this? Thanks

推荐答案

public static String AsciiToBinary(String asciiString){  

          byte[] bytes = asciiString.getBytes();  
          StringBuilder binary = new StringBuilder();  
          for (byte b : bytes)  
          {  
             int val = b;  
             for (int i = 0; i < 8; i++)  
             {  
                binary.append((val & 128) == 0 ? 0 : 1);  
                val <<= 1;  
             }  
            // binary.append(' ');  
          }  
          return binary.toString();  
    }
