Question

在尝试了关于这个主题的每个答案后，我找到了（并且搜索了将近一整天），我无法将字符串格式（变量a）的二进制数据成功转换为字母数字字符串。我的问题是“我做错了什么？”

最终我想要打印出一个人类可读的字符串，例如“Hello There”，这将是整数87521618088882520788922981（输入将更改为long。）

int input = 256;
    int maxInt = 10000;
    String result = "";
    String o;
    String a = "";
    String stringByte;
    char c;
    int pos;
     while (input <= maxInt){
         System.out.println("Input:          " + input);
         o = Integer.toBinaryString(input);
         System.out.println("Binary String:  " + o);
         System.out.println("Remainder:      " + o.length() % 8);
         if (((o.length() % 8) == 0) && (o != "0")){
             //is a multiple
            a = o;
        }else{
            a = o;
            while ((a.length() % 8 != 0)){
                a = "0" + a;
            }
         }
         //divide into bytes
         System.out.println("Zero-putter:    " + a);
         int numBytes = a.length()/8;
         pos = 1;
         System.out.println("Bytes Received: " + numBytes);
             byte[] bytes = a.getBytes();
             String str = new String(bytes);
         System.out.println("Character:      " + str);
         System.out.println("-----------------------------");
         input++;
         try {
                Thread.sleep(1000);                 //1000 milliseconds is one second.
            } catch(InterruptedException ex) {
                Thread.currentThread().interrupt();
            }
        }



     }

Answer 1

您可以尝试使用BigInteger将字节数组转换为无限数字。

1-将您的字符串转换为字符数组

char[] chars = myString.getBytes();

2-转换字节数组中的字符数组（字节b =（字节）c，其中c是字符）

byte[] bytes = new byte[chars.length];
for(int i=0; i<bytes.length;i++){
  bytes[i] = (byte)chars[i];
}

3-使用BigInteger

BigInteger myData = new BigInteger(bytes);

4-显示为字符串

myData.toString();

如何在Java中将二进制字符串更改为字母数字字符串？
