1.字符串(汉字)转换为十六进制 主要使用字符串.charCodeAt()方法,此方法返回一个字符的Unicode值,再用toString(16)方法,该方法是先将数字对象转换为二进制,再把二进制转化为16进制. var str = "赵兄托我帮你办点事"; var val = ""; for(var i = 0; i < str.length; i++){ if (val == "") val = str.charCodeAt(i).to

Given an integer, write an algorithm to convert it to hexadecimal. For negative integer, two’s complement method is used. Note: All letters in hexadecimal (a-f) must be in lowercase. The hexadecimal string must not contain extra leading 0s. If the nu
最简单的方法: 利用javax.xml.bind包下的DatatypeConverter printHexBinary public static java.lang.String printHexBinary(byte[] val) Converts an array of bytes into a string. Parameters: val - An array of bytes Returns: A string containing a lexical representation
