Question

java里如何将汉字转换成16进制编码 ?

Answer 1

可以调用show("在国",16)生成16进制，17、22........，最多支持到36
import java.util.ArrayList;
import java.util.List; public class ThritySix { /**
* @param args
*/
public static void main(String[] args) {
String str = "中华人发共和国";
System.out.println(show(str,36));
} public static List show(String source, int p) {
List list = new ArrayList();
char[] arr = source.toCharArray();
for (char c : arr) {
StringBuilder sb = new StringBuilder();
int tt = c; int ii = 0;
System.out.println(tt);

while (tt != 0) {
ii = tt % p;
if (ii > 9) {//如果大于9则用A-Z代替
sb.insert(0, getData(ii));//插入到最前面
} else {
sb.insert(0, ii);//插入到最前面
}
tt = tt / p;
}
list.add(sb.toString());
}

return list;
}

Answer 2

public static void main(String[] args) {
// TODO Auto-generated method stub
String s = "123abc中国 ";
try {
byte[] b = s.getBytes();
String str = " ";
for (int i = 0; i < b.length; i++) {
Integer I = new Integer(b[i]);
String strTmp = I.toHexString(b[i]);
if (strTmp.length() > 2)
strTmp = strTmp.substring(strTmp.length() - 2);
str = str + strTmp;
}
System.out.println(str.toUpperCase());
} catch (Exception e) {
e.printStackTrace();
}
}
