When Loading Image Using BufferdImage and ImageIO it Clears my Whole Frame and Does Not Display Image - image

Question

I and making a program using basic GUI involving buttons, frames, and panels, and everything was fine until I tried to load an image from my project folder. When i add the line of code
try{
titleImage = ImageIO.read(new File("mouse_title_resize.png"));
}
catch(Exception e){}
After I run the program my whole frame just becomes blank whereas before I had some JButtons on it.All the code I had before the try-catch line worked perfectly fine and I tested to see that the only thing that breaks it is this line of code. I receive no errors or anything and I have the image in my project folder and it seems that the image loaded fine, except it wont show up on the frame, and everything else on the frame disappears. I just don't understand why it clears my whole frame when i load the image.
Here is the full code:
This is the class that extends JFrame
package mouse.click.game;
import java.awt.Dimension;
import java.awt.Point;
import java.awt.Toolkit;
import javax.swing.JFrame;
public class MouseClickGame extends JFrame {
//Constants to define the frame width and height including borders
public final int FRAME_WIDTH = 600;
public final int FRAME_HEIGHT = 600;
//Dimension from Toolkit to be able to get width and height of screen
public Dimension sizeTool = Toolkit.getDefaultToolkit().getScreenSize();
//Using sizeTool to get width of screen
public double xResolution = sizeTool.getWidth();
//Using sizeTool to get height of screen
public double yResolution = sizeTool.getHeight();
//Creating a point object that is defined as the center of the screen
public Point middleOfScreen = new Point((int) (xResolution / 2) - (FRAME_WIDTH / 2), (int) (yResolution / 2) - (FRAME_HEIGHT / 2));
public MouseClickGame() {
super("WELCOME :D");
setSize(FRAME_WIDTH, FRAME_HEIGHT);
setResizable(false);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
setLocation(middleOfScreen);
add(new MouseClickPanel());
}
public static void main(String[] args) {
//Calling constructor
MouseClickGame mainClickGame = new MouseClickGame();
}
}
And here is the class that extends JPanel (these are the only two classes in my project)
package mouse.click.game;
import java.awt.Dimension;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.Box;
import javax.swing.BoxLayout;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class MouseClickPanel extends JPanel {
JButton buttonPlay = new JButton("Play");
JButton buttonContinue = new JButton("Continue");
JButton buttonOptions = new JButton("Options");
JButton buttonExit = new JButton("Exit");
BoxLayout boxLay = new BoxLayout(this, BoxLayout.Y_AXIS);
Dimension menuButtonSize = new Dimension(300, 30);
Dimension spacingBetweenButtons = new Dimension(0, 30);
BufferedImage titleImage;
public MouseClickPanel() {
try {
titleImage = ImageIO.read(new File("C:\\Users\\Justin\\Desktop\\mouse_title.png"));
} catch (IOException e) {
}
setLayout(boxLay);
add(Box.createVerticalGlue());
add(new JLabel(new ImageIcon(titleImage)));
//Adding glue to force buttons away from top of panel
add(Box.createVerticalGlue());
add(buttonPlay);
//Vertical spacing between buttons
add(Box.createRigidArea(spacingBetweenButtons));
add(buttonContinue);
add(Box.createRigidArea(spacingBetweenButtons));
add(buttonOptions);
add(Box.createRigidArea(spacingBetweenButtons));
add(buttonExit);
//Adding glue to force buttons away from bottom of panel
add(Box.createVerticalGlue());
//Aligning all buttons to centered horizontally
buttonPlay.setAlignmentX(Box.CENTER_ALIGNMENT);
buttonContinue.setAlignmentX(Box.CENTER_ALIGNMENT);
buttonOptions.setAlignmentX(Box.CENTER_ALIGNMENT);
buttonExit.setAlignmentX(Box.CENTER_ALIGNMENT);
//Setting button sizes
buttonPlay.setMaximumSize(menuButtonSize);
buttonContinue.setMaximumSize(menuButtonSize);
buttonOptions.setMaximumSize(menuButtonSize);
buttonExit.setMaximumSize(menuButtonSize);
}
}
Literally if i get ride of the titleImage = and add(new JLabel) lines everything goes back to normal

My guess is that you've just got the path wrong -- a common mistake. In that case, you should be getting an exception like:
Exception in thread "main" javax.imageio.IIOException: Can't read input file!
at javax.imageio.ImageIO.read(ImageIO.java:1301)
at jonathanrmiproject.MyProject.main(JonathanRmiProject.java:24)
This simple example works for me:
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.naming.NamingException;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class MyProject {
public static void main(String[] args) throws NamingException, IOException {
BufferedImage img = ImageIO.read(new File("myimage.jpg"));
JLabel label = new JLabel(new ImageIcon(img));
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.getContentPane().add(label);
f.pack();
f.setLocation(200, 200);
f.setVisible(true);
}
}
I am using Netbeans IDE, and I have saved the image file to "C:\Users\David.Sharpe\MyProject\myimage.jpg".
I should add that if this is not the case, and you do have the correct path, then you need to post a more detailed question so that someone can help you. Include the code to reproduce the problem.

UPDATE: Wow literally the reason it wasn't showing up was because i called setVisble(true) too early. I can't believe it was something that simple. I guess that explains why one time everything would show up and it would be fine but then every time after nothing showed up.
So in my constructor I had
public class MouseClickGame extends JFrame {
public MouseClickGame() {
super("WELCOME :D");
setSize(FRAME_WIDTH, FRAME_HEIGHT);
setResizable(false);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setLocation(middleOfScreen);
setVisible(true);
add(new MouseClickPanel());
}
public static void main(String[] args) {
//Calling constructor
MouseClickGame mainClickGame = new MouseClickGame();
}
}
when all I had to do was put the setVisble() after the add(newMouseClickPanel())
Thank you DavidS for your suggestions :D
