java - 在 Java 中从二进制转换回其字符串值

Question

目前，我有一个值为“0100100001101001”的字符串(这是单词“Hi”的二进制)。我想弄清楚如何获取该字符串并将其转换回单词“Hi”

我用过

String s = "Hi";   
byte[] bytes = s.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;      
    }         
}   
s = binary.toString();

有点像..

BigInteger val = new BigInteger("0100100001101001", 2);
String hi = new String(val.toByteArray());
