把字符串数组转换为16进制字符串 import java.security.MessageDigest; public class StringUtil { public StringUtil() { super(); } public static String str; public static final String EMPTY_STRING = ""; private final static String[] hexDigits = { "0", &q
我们知道任意进制转换为十进制,都是乘以基数的多少次方,然后相加: 十进制转换为任意进制,都是除以基数,然后倒着取余数: 所以这里是用十进制数中转,实现任意进制数的转换 #include<iostream> #include<algorithm> #include<math.h> #include<stack> #define ll long long #define M 0x3f3f3f3f3f using namespace std; ll change1
//将byte[]转换为16进制字符串 public static String byte2hex(byte[] b) { StringBuilder hs = new StringBuilder(); String stmp; for (int n = 0; b != null && n < b.length; n++) { stmp = Integer.toHexString(b[n] & 0XFF); if (stmp.length() == 1) hs.append(
