如何從偶數/奇數狀態中刪除最後一個|
?如何從保留字符列表中刪除最後一個字符?
實施例:
import java.io.*;
import java.net.Socket;
public class Test {
public static String _noManualTraceIt = "0008e07cd8ec6cfdb900283508004500004a7d8d400080060000c0a80087c0a800c6c6931388956304704eebd50c5018ffff82da0000674500000504000000000000030000000000000000000000060000000000ff210000";
public static void main(String[] args) throws IOException {
System.out.println(wireShirk(_noManualTraceIt));
}
public static byte[] wireShirk(String bytes) throws IOException {
String temp = "";
String replaceIfOnLastFound = "||&|\r\n|\n\r|etc|etc";
int _i = 0;
do {
temp += bytes.charAt(_i);
if(_i%2 ==0) {
} else {
temp += "|";
}
System.out.println(bytes.length() + " " + _i + " " + two.charAt(_i) + " " + temp);
_i++;
} while(_i<bytes.length());
bytes = temp; // << replaceIfOnLastFound any of those characters
// | or & or \r\n or etc etc from that variable
String byteArrayStr[] = bytes.split("\\|");
byte bytesArray[] = new byte[byteArrayStr.length];
for (int i = 0; i < byteArrayStr.length; ++i) {
bytesArray[i] = (byte) (Integer.parseInt(byteArrayStr[i], 16));
}
return bytesArray;
}
}
輸出:

您如何期望從字符串中刪除最後一個字符?這並不難。 –
