Mouse Handler in Separate Class not Working

I am writing a Crazy Eights game and trying to have mouse control added in. I just starting writing it but I can't verify if it's working or not. I've added System.out.println() to the pressed and released event calls but no output happens. I just need to get it working and be able to see an output of some kind for debugging. I've also tried to use another example on stackoverflow to help me out but I'm still having issues. The below code is what I'm working with. Let me know if you need to see another class.
Thanks

You have to add the MouseListener to a component: frame.addMouseListener(...)

Java Game Programming Part 2: Disappearing Images

For a school computer project I decided make a Pac-Man style game in Java (with two other people). None of us have much experience, so we've essentially been teaching ourselves up to this point. We've made quite a bit of progress, but we seem to have reached a standstill at this point.
How can we make the candies disappear when Fatman runs over them? We've tried using repaint, but we can't seem to get things to work properly.
(I have other things I need help on but they are in different questions)
Thank you for your help!
Here is our code so far:
Maze Class:
package Fatman;
import javax.swing.*;
public class Maze {
public static void main(String[] args){
new Maze();

public Maze(){

f.setTitle("Fatman!");

Any ideas?

well i don't think you could be two thirds of a 3 man group, unless you ate one of your members, but on saying that....
Your question is more suited to https://gamedev.stackexchange.com/ as its more of a game development question in my opinion.
However.what you could do, is set the candies position offscreen (for example: candy.x = -100;)
on saying that though, where is your game loop?
public void startGame(){
} public void stopGame(){
} public void update(){ //forces graphics and user input to update the
games state }
also consider going to www.java-gaming.org they have awesome tutorials to help you out.

Nothing in Player.move() is eating dots. You have to update the value of variable Map.Map[] to keep track of what it's supposed to represent. Otherwise this code is just empty words/symbols that hack at doing one instruction from the programmer at a time but don't use the power of a programming language to let the computer do work according to the conditions it meets.

I dont want to be mad but you are defining different folder locations
in some places "G://sonali_java//mygane//object.png", check "mygaNe"
in some places "G://sonali_java//mygame//Map.txt", check "mygaMe"
Are you sure while loading it does not throw a NullPointerException ?

Are you aware that you can, place code like
public void draw(Graphics g){
g.drawImage(playerImg, getX(), getY(), null);
}
in your player class, thus leaving the player class with drawing the player and simply calling the players draw method inside your Board paint method? This can also be done for drawing the map. Remember to call the draw methods in the paint method.
ALSO, THIS
ImageIcon img = new ImageIcon("G://sonali_java//mygane//object.png");
check your directory location

How can i add time limitation in a Maze Game using java

I am making a maze game in Java. I have made a maze board, A start point and a end point. When I reach the end point then it exit and show a winning message. But I can not add a time limitation. Suppose player have to reach the end point with 30 seconds otherwise he lose the game. Please help me.
Here is my code i have done so far.......
Maze.java
package Maze;

public class Maze {
public static void main(String args[])
{
new Maze();
}
public Maze()
{
JFrame f= new JFrame();
f.setTitle("Maze Game");
f.add(new Board());
f.setSize(460,480);
f.setLocationRelativeTo(f);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}

elapsedTime=elapsedTime/1000;

timer.start();
}

You can do a work around ,Add a timer class which will execute at x seconds and keep on calculating the total seconds in a variable and when the limit is crossed you can stop your program.
