写个代码跑
public class Main {
public static void main(String[] args) throws Exception{
String result = "";
int t = 51;
String[] paname = "com.njctf.mobile.easycrack".split("\\.");
for (char ch : paname[paname.length - 1].toCharArray()) {
//System.out.println(ch);
t ^= ch;
result = result + ((char) t);
}
System.out.println(result);
}
}
