Rat And Maze Protocol
Apr 17, 2014
So far i've built an array of char W= wall, O=open, R= rat, and P= path
I have another class "RAT" which will navigate through the maze. so im having trouble with the method to get the position of the rat when it is navigating through maze. this is what i have.
public class FinalMaze {
static char[][] mazeArray = new char[][] {
{'o','o','o','o','o','o'},
{'o','w','w','r','w','o'},
{'o','w','p','p','w','o'},
{'o','w','p','w','w','o'},
{'o','w','p','p','w','o'},
{'o','w','w','p','w','o'},
{'o','w','w','p','w','o'},
{'o','o','o','o','o','o'},
};
[Code] .....

I am doing an assignment which involves creating a maze and a ball that needs to go through the maze to an end tile then stop the scenario. The maze is made up of 208 buttons in a Jbutton Grid layout. I am replacing certain buttons with a brown tile icon to make up the maze. The ball needs to run along those brown tiles as its path and not be able to move off the brown tile icon images.
I have built the maze and have got quite far with this but now I am stumped on the concept of keeping the ball within the boundary edges and on the brown tiles. I have been told to use if statements, but not had the process explained to me in a way I can understand.

im having 2 simple problems that are for somereason going above my head right now.
1: i need to start the program at the first possible position (row 0 col 0)
2: i need to be able to read multiple mazes in one file.
Code:
import java.io.*;
public class Driver {
private File mapFile = new File("map.txt");
private char[][]maze;
private char pathMarker = '2';
private int row,col,ndx=0;
public static void main(String[] args) {
Driver d = new Driver();
[code]....

So what I'm trying to do is write a code in java which finds a path through a maze. I want it to go through the maze and determine if there's a * symbol at that location or not. If there is a * symbol at the specified location then the program would search for another position until it finds one without the * symbol and if it can't then I'll have the program return null. I also want it to implement backtracking which I'm not sure how to do. Here's my code so far
private boolean findPath(int fromRow, int fromCol, int toRow, int toCol){
boolean solved = true;
for(int i=fromRow; i<toRow; i++){
for(int j=fromCol; j<toCol; j++){
if (x[i][j] == ('*')){
//do something
}
}
}
return false;
}
the code isn't finished yet however what I'm not sure is what do I do with the if statement and how do I implement backtracking?

I made a kind of maze game that includes the class keylistener and orients a object, i can't find where the program tracks this object (where its x and y coordinates are). So now my object can move freely through all walls and i want it to bounce back or at least something to happen when the object reaches a wall.
I want to find a way to limit my objects movement and because i cant find where the coordinates or variable for this object is i cannot limit its movement

I have to write a code for File Transfer Protocol! It says that I only need to write code for client, but it also says that I have to run the program and send some files to server. I guess than I also need server side as well. I have to write my own classes, I cannot import some existing classes. I have to connect to the server with password and username and after that send some files to the server. I don't know anything about FTP. Can i maybe do this by Sockets and ports? I worked something with that.

My Mail reading functionality is not working properly using POP3 protocol. Actually I can read the mail but the status is not changed as read.
Java Code:
public static void main(String arg[]) throws MessagingException, IOException{
String host = "pop.test.net";
String user = "test@beq.com";
String password = "abc10";
String protocol = "pop3";

I have to write a client and server class for a UDP protocol sending integer numbers by UDP packets. So far i have this;
Client Code:
import java.io.*;
import java.net.*;
class UDPClient {
public static void main(String args[]) throws Exception {
BufferedReader inFromUser =
new BufferedReader(new InputStreamReader(System.in));
[Code] ....
But i now need to change this so that:
The client;
1. Reads an integer from keyboard input and stores its value in a UDP packet.
// byte[] send = ByteBuffer.allocate(4).putInt(num).array(); ???
2. Sends the UDP packet to the server, on port number 1999;
3. Listens for UDP packets from the server (until it receives a packet with a non-positive number; see
step (b) below). While listening:
(a) Once it receives a UDP packet from the server, it subtracts 2 from the integer value num contained in it.
// int num = ByteBuffer.wrap(receive).getInt(); ???
(b) Checks the integer value num: if the value is greater than 0 (num>0) then the client stores it in a new UDP packet and sends the packet to the server; otherwise (num<=0) the client terminates.
The Server;
1. Listens on port 1999;
2. For each UDP packet it receives from a client:
(a) extracts the integer value n contained in it;
(b) decreases the value of n by 2;
(c) sends back to the client a UDP packet containing the new value of n.
