首先我们会将十六进制字符串转为byte数组: StringhexString="48656C6C6F20576F726C64";byte[]byteArray=newbyte[hexString.length()/2];for(inti=0;i<hexString.length();i+=2){byteArray[i/2]=(byte)((Character.digit(hexString.charAt(i),16)<<4)+Character.digit(hexString.charAt(i+1),16));} ...
baos.write((hexString.indexOf(bytes.charAt(i)) << 4 | hexString.indexOf(bytes.charAt(i + 1)));return new String(baos.toByteArray());} }

BigInteger类是Java中用于处理大整数的类,它提供了各种方法来进行大整数的运算和转换。 要将HEX String转换为BigInt,可以使用BigInteger类的静态方法valueOf()或者构造方法BigInteger(String val, int radix)。 下面是一个示例代码: 代码语言:java 复制 importjava.math.BigInteger;publicclassHexToBigInt{publicstaticvoi...
