I have to build the attached GUI as exercise (exercise.jpg), but I am getting a lot of errors on the console. OK so the code is available on pastebin here: URL>...An excerpt of errors is attached. I don't understand why I get them. Basically the compiler is picking on new GridBagCostraints() and new Insets().

How do you use GridBagLayout and CardLayout together?
I'm trying to add these buttons to a panel, but it breaks the GridBagLayout, here's what is in the doc;
Java Code:
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
[Code] .....
I'm trying to do:
Java Code:
JPanel m = new JPanel();
button = new JButton("Button 1");
c.fill = GridBagConstraints.HORIZONTAL;
c.gridx = 0;
c.gridy = 0;
m.add(button, c);
[Code] .....
However it reverts as though it's using flowlayout. What is it I'm missing?

I decide to make a new GUI just for fun and practise and i want to learn more about Layouts.. right know i am try to understand some staff about GridBagLayout.
I want to make a GUI with this Layout :
So..first i am a frame with borderlayout then i put a JMenuBar and bla bla bla and i create panel with GridLayout which i put on myFrame.add(panel1,BorderLayout.WEST) and also i make an another JPanel which i put of the Center of main Frame (myFrame.add(panel2,BorderLayout.Center))
when i run the program i get this GUI :
Now the problem is that i can't put the JButton on the top of the gridLayout just to look like the first picture.. i Read about anchor and i try to
gbc.anchor = GridBagConstraints.NORTH; but without results.. still the components are on the middle of the JPanel..
Here is my Code () :
Java Code:
import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
[Code] .....

I'm trying to make a simple window that displays 5 text fields on x number of rows, depending on what I set x to. Attempting to do this with GridBag Layout but I can't seem to get a new row started. The closest I can get is to repeat the same fields on the same row. I'm trying to modify the row by putting the code in a loop and setting gridy = i, that way each iteration should place the code lower than the first. I'm new with GridBagLayout so I'm probably missing something simple. The constructor with the loop is below. I've commented out code that doesn't seem to work but left the gridx and gridy.
public PAMCalculator()
{
setTitle("PAM Calculator");
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(WIDTH, HEIGHT);
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints gridConstraints = new GridBagConstraints();
setLayout(gridbag);
[code]....

I am working on a program to have a user input two positive integers and then finding the greatest common denominator between the two. My problem is, I don't know how to display the number (num2) that is returned after the method. Putting a simple System.out.println gives me the error "unreachable code".
import java.util.Scanner;
public class ****
{
public static void main(String[] args)

I have a problem with one method for my assignment. This is the requirement for this method: "This method uses a loop to list all accounts contained in the Array, adding each account details to a String, before outputting to screen in the format specified in the screenshot below. Ensure that there are no out of bounds exceptions by checking if each array slot has an account object before adding its details to the output String. (arrayname[index] != null)"This is my code for this method:
public void listAllAccounts() {
String allAccountsString = "List of all accounts:
";
for(int i = 0; i < ACCOUNT_SPACES; i++) {
//allAccountsString += accountArray[numAccounts];
if (accountArray[i] !=null) {
allAccountsString += accountArray[i].toString() + "
" ;
}
}
JOptionPane.showMessageDialog(null, allAccountsString);
The problem is that the Message Dialog does not display the accounts I have already created. It just displays "List of all accounts:
";

I created a instance of a class AddItemView, inside StartUpMenuController. I then passed it into the class, the main method is below showing that as well. However when I do this:
else if(e.getSource()==menu.addBtn)
{
new addItem();
}
I get an error, little red line on the bottom of the text. I am testing the frame at the moment to make sure it is what I want before I move on to the Controller side of it. I just want to display it and go from there.
package mainMenu.Home.DataBase;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import addItemBtn.Home.DataBase.AddItemView;
public class StartUpMenuController
{
StartUpMenu menu;
AddItemView addItem;
[code]...
Not sure if this is the issue but the class I am making a new instance of is in a different package. I imported the package though.

why my image may not be showing. Note I am using eclipse.
Window.java:
import javax.swing.*;
public class Window {
private JFrame gameWindow;
public Window() {
gameWindow = new JFrame("Tamagotchi!");
[code]....
I have used file.exists() and this returns true, and file.length() which returns the correct file size.
System.out.println(backgroundImage) returns "splash.png" so thats ok.
Why then is my image not showing?

I'm learning about inheritance and part of my problem is to create an Order with methods, then an UpdateOrder where the total price is changed by adding four dollars to it, and then a main method displaying a few orders. I've copied all three below in order. My question is when I run the program it will display the totalprice() first for the second order followed by name, number, etc.what you override always displayed first regardless of the order you put them in? (The issue is at line 31 on the third code.)
import javax.swing.JOptionPane;
public class Order { //superclass
private String customerName;
private int customerNumber;
protected int quantityOrdered;
protected double unitPrice;
protected double totalPrice;

I need to display my calculations in a table format using loops.
//Imports
import java.util.*;
import java.text.*;
public class YourLoanCalculator {
[code]....
The increments are correct, but I wanted them listed under the "Payment #:" column. I figure that if I do that, I can also correctly display the interest, principal, unpaid balance and total interest paid at that point, right?

As you can see instead of displaying the champion name it is displaying the memory location and I do not know how to fix it.

import java.awt.event.*;
import java.awt.Graphics;
import java.awt.Color;
import java.awt.Dimension;

1. Why, when I press "New" rapidly, will it skip painting shapes sometimes/adding to totcount.
2. How can I make it so that The box in the background(which is currently connected in the wrong way as I was getting an error when I connected it correctly) can be modifiably large. AKA, I want to draw a grid in the background that can be different sizes, depending on the values of a variable xsize and ysize.
3. What can I do to clean this up? All I want it to do is display the convex hull of the four points given in the int[][] displaypoints.

Yes my JPanel is not displaying all the time like you would think it would. Before you beat me up yes I am a bit new I am just working on the GUI part of java over my summer break. Obviously it is not suppose to do that. Secondly, As you can see i am using the alphabet to create JButtons. Shouldnt there be an easier way to use a for( loop) . I tried before but I didn't want to get too side tracked.
Java Code:
import javax.swing.*;
import java.awt.*;
public class hello {
private JFrame alphaframe1;
private JFrame alphaframe2;

I have a JScrollPane and JTable inside. In the right column of the table at the end (south) I made a ChartPanel in one of the classes where I make the design for the Frame:
Java Code:
ChartPanel chartpanel = new ChartPanel(pieChart);
pCapturing.add(chartpanel, BorderLayout.NORTH); mh_sh_highlight_all('java');
And when I click on any row above, from the list in the column, I would like an appropriate pie chart to be drawn.
I need here (in another class where I define the getTableCellRendererComponent) to enter a code to display the chart in the last row of the panel:
Java Code:
PieChart3 pie=sectionsChartProvider.getSectionPieChart(section);
...
...
if((hasFocus) || (isSelected)) {
if(column == 0)
setBorder( new MatteBorder(1, 1, 1, 0, colorBorder) );
[Code] .....
But, I don't know how to do this. I also have a class for drawing the pie chart.

So I have this
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Which works fine... But if I try and add another document under the if VAL === replaced then nothing works and neither of the boxes appear.
function checkvalue (val) {
if(val==='replaced')
document.getElementById('check1h').style.display='block';
document.getElementById('check1n').style.display='block';
else if (val==='checked')
document.getElementById('check1h').style.display='none';
else
document.getElementById('check1h').style.display='none';
}
Is this not possible?
Also, Both of my input type are set up like this...
<input type='text' style='display:none' name='check1n' id='check1n' placeholder='Name of Part' />
<br>
<input type='text' style='display:none' name ='check1h' id='check1h' placeholder='Part Number' />

i have got an array which has come from a text file.
Parts of the array have been placed into a string.
So string one will have about 50 different values which I am able to print into the console using System.out.println("FirstString"); This prints all of the variables from the array so I end up with 50 words.
I am now trying to get this into a HTML document.
I have correctly done this and I get some out put when the webpage opens.
My problem is that I only have 1 work which is displayed.
