This is the code to make a mouse maze with recursion using a stack and a list with a GUI in Java.
First we will make a Mouse class
Mouse.java
import java.util.ArrayList;
import java.util.List;
import java.util.Stack;
public class Mouse {
public int x,y;
public Stack<Coordinate> decisions;
public List<Coordinate> solution;
public Mouse(int x, int y){
this.x = x;
this.y = y;
decisions = new Stack<Coordinate>();
solution = new ArrayList<Coordinate>();
}
}
Then we will make the coordinate class
Coordinate.java
public class Coordinate {
public int x,y;
public Coordinate(int x,int y){
this.x = x;
this.y = y;
}
@Override
public boolean equals(Object obj) {
boolean sameSame = false;
if (obj != null && obj instanceof Coordinate)
{
if(this.x == ((Coordinate)obj).x && this.y == ((Coordinate)obj).y){
sameSame = true;
}
}
return sameSame;
}
}
Now its time for the decision class
Decision.java
public class Decision {
public boolean up,down,left,right;
public int x,y;
public Decision(int x, int y){
up = down = left = right = false;
this.x = x;
this.y = y;
}
public Decision(boolean up,boolean down,boolean right,boolean left){
this.up = up;
this.down = down;
this.right = right;
this.left = left;
}
public void setLeft(boolean left){
this.left = left;
}
public void setRight(boolean right){
this.right = right;
}
public void setUp(boolean up){
this.up = up;
}
public void setDown(boolean down){
this.down = down;
}
@Override
public String toString() {
// TODO Auto-generated method stub
return x + " x -- y " + y;
}
}
Now we have to make the maze class which does most of the hard work
Maze.java
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Rectangle;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Random;

public class Maze extends JComponent{
public char[][] maze = null;
public Rectangle[][] rects = null;
public boolean mousebool = false;
public boolean backtrack = false;
public Mouse mouse;
public Random random = new Random();
public Coordinate startingPoint;
public boolean first = true;
public boolean solv = true;
public int lastx,lasty;
public String navigation = "working!!!";
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
if(maze != null){
for(int i = 0;i < maze.length;i++){
for(int j = 0;j < maze[0].length;j++){
if(maze[i][j] == '1'){
g.setColor(Color.BLACK);
g.fillRect(rects[i][j].x, rects[i][j].y, rects[i][j].width, rects[i][j].height);
g.setColor(Color.WHITE);
g.drawRect(rects[i][j].x, rects[i][j].y, rects[i][j].width, rects[i][j].height);
}else if(maze[i][j] == '0'){
g.setColor(Color.white);
g.fillRect(rects[i][j].x, rects[i][j].y, rects[i][j].width, rects[i][j].height);
g.setColor(Color.BLACK);
g.drawRect(rects[i][j].x, rects[i][j].y, rects[i][j].width, rects[i][j].height);
}
}
}
if(mousebool){
g.setColor(Color.PINK);
g.fillOval(rects[mouse.x][mouse.y].x, rects[mouse.x][mouse.y].y, rects[mouse.x][mouse.y].width, rects[mouse.x][mouse.y].height);
}
}
}
public void setMaze(char[][] maze){
mousebool = false;
this.maze = maze;
rects = new Rectangle[maze.length][maze[0].length];
for(int i = 0;i < rects.length;i++){
for(int j = 0;j < rects[0].length;j++){
rects[i][j] = new Rectangle(i * (getWidth()/rects.length),j * (getHeight()/rects[0].length)
,getWidth()/rects.length,getHeight()/rects[0].length);
}
}
repaint();
}
public void setMouse(int x,int y){
mousebool = true;
mouse = new Mouse(x,y);
startingPoint = new Coordinate(x,y);
mouse.solution.add(new Coordinate(x,y));
mouse.decisions.push(new Coordinate(x,y));
first = true;
repaint();
}
public void solve(){
if(mouse.x > 0 && mouse.x < maze.length - 1 && mouse.y > 0 && mouse.y < maze[0].length - 1 && mouse.decisions.size() > 0){
//System.out.println(wasHere(coord) + "now");
//north
System.out.println(wasHere(new Coordinate(mouse.x,mouse.y - 1)) + "north");
if (!(maze[mouse.x][mouse.y - 1] == '1') && !wasHere(new Coordinate(mouse.x,mouse.y - 1))) mouse.decisions.push(new Coordinate(mouse.x,mouse.y - 1));
//east
System.out.println(wasHere(new Coordinate(mouse.x + 1,mouse.y)) + "east");
if (!(maze[mouse.x + 1][mouse.y] == '1') && !wasHere(new Coordinate(mouse.x + 1,mouse.y))) mouse.decisions.push(new Coordinate(mouse.x + 1,mouse.y));
//west

Coordinate coord = mouse.decisions.pop();
mouse.x = coord.x;
mouse.y = coord.y;
mouse.solution.add(coord);
ActionListener taskPerformer = new ActionListener() {
@Override
public void actionPerformed(ActionEvent arg0) {
solve();
}
};
javax.swing.Timer t = new javax.swing.Timer( 250, taskPerformer);
t.setRepeats(false);
t.start();
//solve();
repaint();
}else{
solv = false;
if(mouse.decisions.size() == 0){
mouse.solution.clear();
navigation = "there is no solution";
}else{
mouse.solution.clear();
findPath(startingPoint.x,startingPoint.y);

}
}
//solve();
}
public boolean findPath(int x,int y){
if(x < 0 || y < 0 || x > maze.length - 1 || y > maze[0].length - 1)return false;
if(!(x > 0 && x < maze.length - 1 && y > 0 && y < maze[0].length - 1) && maze[x][y] == '0')
{

}
repaint();
}
public String Navigation(){
return navigation;
}
}
And finally the Main class to make the GUI
Main.java
import java.awt.BorderLayout;
import java.awt.Container;

public class Main {

}
SwingUtilities.invokeLater(new Runnable() {
public void run() {

}
public static void create(){
JFrame frame = new JFrame("Mouse Maze");
final Maze maze = new Maze();
frame.setSize(500, 500);
frame.setLocation((int)(Toolkit.getDefaultToolkit().getScreenSize().getWidth()/2)-264,

int returnVal = chooser.showOpenDialog(null);
if(returnVal == JFileChooser.APPROVE_OPTION) {
try {

panel.add(pickFile,BorderLayout.CENTER);
panel.add(textFile,BorderLayout.WEST);
JButton setMouse = new JButton("Set Mouse");
final JTextField mouseText = new JTextField("x,y",15);

final JLabel error = new JLabel("ERROR MESSAGES!!!!");
panel2.add(solve,BorderLayout.NORTH);
panel2.add(traverse,BorderLayout.CENTER);

traverse.addActionListener(new ActionListener(){

maze.TraverseMouse(0);
}
});
solve.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent arg0) {
// TODO Auto-generated method stub
maze.solve();
error.setText(maze.navigation);
}
});
setMouse.addActionListener(new ActionListener(){
@Override
public void actionPerformed(ActionEvent arg0) {
String mousePosition = mouseText.getText();
String[] splitposition = mousePosition.split(",");
try{
int x = Integer.valueOf(splitposition[0]);
int y = Integer.valueOf(splitposition[1]);
if(x >= width || y >= height){
error.setText("those coordinates are not in range of your maze, try again, 0-"+ (width - 1)+",0-"+(height-1));
}else if(maze1[x][y] == '1'){
error.setText("you cannot place the mouse on a wall, try again");
}else{
maze.setMouse(x, y);
error.setText("coordinates set.");
}
}catch(NumberFormatException e){
error.setText("You Must enter the mouse position \"x,y\" example: 10,20");
}catch(ArrayIndexOutOfBoundsException e){
e.printStackTrace();
error.setText("You Must enter the mouse position \"x,y\" example: 10,20");
}
}
});
//frame.add(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//makes it so you can close
frame.setVisible(true);
//char[][] ch = new char[][]{{'1','1','1','1'},{'1','0','0','1'},{'1','0','0','1'},{'1','1','1','1'}};
//maze.setMaze(ch);
}
}
You will have to use a text file in this format where a 1 is a wall and a 0 is part of the path remember .txt file the first line means 10 width and 5 height for the maze
10 5 1111111111 1010001111 1011011111 1011000011 1111111111
You can try it and alter it to your own code, thanks for reading.
