publicStringtoHex(int num) {returnInteger.toHexString(num); } 03 第二种解法 此解法的思路来自于String toHexString(int i)的源代码,先将16进制所用到的字符放入一个字符数组,从'0'到'f'依次排列,再定义一个字符串。先将num和15进行与(&)运算,与运算的规则是同1为1,即将num转为二进制数和二进制数1111...
方法1容易理解且不容易出错,方法4已经由其他人帮我们封装好了实现,因此避免了我们自己实现而可能导致的出错。 参考链接: Java code To convert byte to Hexadecimal - Stack Overflow
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 number is zero, it is represented by ...

To convert byte array to a hex value, we loop through each byte in the array and use String's format(). We use %02X to print two places (02) of Hexadecimal (X) value and store it in the string st. This is a relatively slower process for large byte array conversion. We can ...
