Program That Puts 2 Images Into Frame Window
Dec 6, 2014I just started to learn Java Swing and I was trying to make a program that puts 2 images into the Frame window. The code itself doesn't have any errors but when I compile it gives a nullpointerexception, I checked the line with the error and it had to do with my image file but I can confirm the name is correct and I tried both using the path and the name of the image in the package but neither is working.
Error message:
Exception in thread "main" java.lang.NullPointerException

Simple Frame Button And Text Label
Jun 2, 2014why this code doesnt work? Its suppose to be a simple frame with a button that puts text to the frame when u click it. The problem is actionPerformed method, when it tries to call the stuff inside the constructor it all goes wrong. I switched the method body with a system.out.println() and it all works fine.
import java.java.awt.Label;
import java.awt.Button
import java.awt.BorderLayout;

Closing Old Pop Up Frame With Existing Action Button
May 27, 2015I am modifying existing code to display graph after pressing calculate button. The graph pop ups in new controller/window. The pop up disappears after closing the application entirely. However I have trouble figuring out if it is possible to close that old/previous pop up and new pop up appears when calculate button is pressed again. Or at least reuse the pop up to display a new graph.
public class AdamCalculationApp extends AbstractCalculation {
/**
* Does a calculation.
*/
public void calculate() { // Does a calculation
control.println("Adam Calculation button pressed.");
double k = control.getDouble("k value"); // String must match argument of setValue
control.println("k*k = "+(k*k));
control.println("random = "+Math.random());

Swing/AWT/SWT :: Jinternalframe Active Frame Different With Java 7?
Jun 24, 2014I am in the progress of updating my code and re-testing after switching from Java 6 to Java 7. When I open multiple JInternalFrames in my application under java 6 I am used to closing the top most internal frame and having the frame immediately under it become the next active frame. When I run the same code under Java 7 I see a different behaviour in as much as when I close the last frame I opened, the next one to become active is the first one.
To illustrate this another way, lets say I open 5 internal frames, 1,2,3,4 & 5
In java 6 when I close frame 5, frame 4 becomes the active frame.
In java 7 when I close frame 5, frame 1 becomes the active frame.
Java Swing Frame Can't Call On Other Methods From Main
Mar 25, 2015I am trying to make a 2d graphical animation using the java swing classes in order to make a frame. I had a basic version working when all of the code was under the main method, but when I moved some into another method it broke it. With y understanding of java my code should work as I create a variable of the method containing the code and then assign the size and exit button. However this causes many problems such as my BeaconFrame method informing me that it is unused when I have used it. Here is my code:
import javax.swing.*;
import java.awt.*;
public class BelishaBeacon {
public void BeaconFrame() {
JFrame frame = new JFrame();
JPanel panel1 = new JPanel();

Trying To Display Array Results In GUI Window JAVA
Sep 16, 2014I am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.
// Bookstore.java
// This program displays information on multiple books

Making A Window For Java Text Based Game
Jan 10, 2015So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic

View Replies View RelatedWhen Click On New Button / All Icons Except Button Just Clicked Don't Display
Oct 16, 2014The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

View Replies View RelatedActivating Inverse Button On Sample Java Applet
Dec 10, 2014Nearly all of hte sample Java Applet is pre-made by the teacher. I'm running into the issue where, if I use the string arithmetic inverse method provided by the textbook, it refuses to recognize variables such as s1, s2, and i. So I'm now trying to use stringbuilder, and running into a similar issue. It doesn't recognize hte symbol "buffer". Under the "else if ( e.getSource() == inverseStr ) {" is where my code starts. The "Your Code Here" was put there by the teacher, and I'm just using it as an easy way to create blank lines if I delete a method that isn't working for me in the above section.

Java Timer - GUI Button Not Linking Back To Code
Jan 12, 2014I have started coding recently and been working on a simple java timer. My problem is that the button does not show any response even though an action has been done via actionlistener.
Example: When I press the "Start Timing" button, it should start timing and output the counter to Static Timer but instead of doing that, it does nothing.
The important bits are under Timer code and Button Start Timing. Is their something that I'm missing?
//--- All imports have been handled ---
public class GUI {
double counter = 1;
double inputA = 1;
int delay = 1000;
Timer timer = new Timer(delay, null);
