Error Setting Value For JSpinner

Apr 19, 2014

I'm using a jSpinner Number model:

Here's my code:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
int qty2, total, payment, change;
String title;

[code]....

I tried using this since the jSpinner's minimum value is 1.. (I want it to reset the jSpinner after updating the database):

jSpinner1.setValue(new Integer(1));

But gives me an error:

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1
at java.util.Vector.elementData(Vector.java:730)

Swing/AWT/SWT :: Show Year Value In A Class That Extends JSpinner

Mar 15, 2014

I am working on a project where i need to show a year value in a class that extends JSpinner.Its working just fine but when i try to set an alignment value for the editor textfield it all falls apart and i know im missing something really critical here but i can't see or find it all i know is that i can't make a proper reference to the textfield component in the editor i use in the correct way or aproach.

public class JNumberSpinner extends JSpinner {
private String actionCommand;
private boolean isEnabled;
private int startValue;
private int columns;
private int alignment;
private SpinnerNumberModel model;
private JSpinner.NumberEditor numEditor;
private JFormattedTextField jTxtEditorView;

Error Setting Up Object - Static Vs Non-static

Apr 3, 2014

This is the overall code:

public class Bank { 
/**
* Customer class.
*/
public class Customer {
private String firstName, lastName, street, city, state, zip;
 
[Code] .....

The error occurs when I attempt to create the new object Account within the main arguments here:

Account munozAccount = new Account(250, "Maria", "Munoz", "110 Glades Road", "Mytown", "FL", "33445");

I'm not sure how to access the generator method, so i'm completely stumped.

Setting A String Using If

Oct 23, 2014

Here are two codes that I am using but I have one that just doesn't work for some reason and the other does. Encode doesn't work. I don't need the Character.isAlphabetic for encode but not sure what I can use with 'if' to set the String encodedString.

Java Code:

private String prepareString(String plainText)
{
String preparedString = "";
for(int i = 0 ; i < plainText.length();i++)
if(Character.isAlphabetic(plainText.charAt(i)))
{
preparedString = preparedString+Character.toUpperCase(plainText.charAt(i));

Setting A Drive Label

Sep 22, 2014

I have been playing around with a snippet I wrote to get the Label on a drive (below). It works fine for me (though I will take any constructive criticism). My question is whether the is a way to set the drive label, purely with Java. I know I could call command line, or even resort to using the Windows API

import java.util.List;
import java.io.File;
import java.util.Arrays;

Setting Background Of JScrollPane?

Aug 19, 2014

My program's tree:

JFrame{
JPanel(That MenuBar at the top)
JPanel(That panel at center with table){
JScrollPane{
JTable
}
}
}

I want to add my custom image to that grey space right there. I guess it is a JScrollPane, because I added that orange background on JPanel that contains it. But when I add this code to my custom class of JScrollPane:

@Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
if(background == null){
background = new ImageIcon(ClassLoader.getSystemResource("tableBg.png")).getImage();
}
g.drawImage(background, 0, 0, null);
}

The result is the same, no changes.

Then I read some documentation. I found this method:

scrollPane.getViewport().setBackground(Color c);

It works, but it accepts only color and I want to add image. Is there any way to do that? Do I need to subclass JViewport and use paintComponent ? If yes, then how to make getViewport() method return my custom subclassed version?

Setting Values In PDF Field?

Dec 12, 2014

I have a PDF file and I have a text file that contains this data. It has the name of a PDF field along with a database table column name.

Text file: pdfFieldEmployee=Employee; pdfFieldStartDate=StartDate; pdfFieldSalary=Salary; pdfFieldExempt=Exempt

I also have this hash map that contains the database table column names along with their corresponding values:

Employee, Don Parker
StartDate, 5/6/2000
Salary, $55000
Exempt, N

How would I read through the text file and the hash map and at the same time do this:

if the pdf field is equal to pdfFieldEmployee, then set pdfFieldEmployee equal to Don Parker.
if the pdf field is equal to pdfFieldStartDate, then set pdfFieldStartDate equal to 5/6/2000.

and so on and so on. I would prefer to do this with a loop because I think it would take less code than writing a bunch of if statements.

Getting And Setting Frame Name From Another Class

Aug 7, 2014

package com.simbaorka101.te.gui;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.ScrollPaneConstants;
import javax.swing.event.DocumentListener;

[code]....

This is my frame class, now I want to be able to change the name of the frame, and get the name with frame.getName() in another class. But I'm not sure how to do this, i tried making a new frame in that class but i feel it's just another frame and not the one i made, also tried something like

public JFrame getFrame(){
this.getFrame();
}

and few variations but it was wrong.

What Does Setting Object Equal To Another Do

Mar 5, 2014

I've seen this done in code:

For example:

Java Code: BufferedImageOp op = new ConvolveOp() mh_sh_highlight_all('java');

What does this mean? Is it creating an object of convolveOP for the BufferedImage class?

What does it mean when you set an object from one class equal to another?

Will it make any difference if I put the last line of code inside the useBean tag ?

<jsp:useBean id="person" class="foo.Person" scope="page" >

<jsp:getProperty name="person" property="name" />

It gives me the same output though....

Setting Brightness With RescaleOp

Jul 3, 2014

When I try to brighten my BufferedImages with RescaleOp, they are cut in half, and not brightened at all. However, strangely enough, when I tried to run the same program on another computer they were not cut in half, but only one half of the image was brightened. Here are two images displaying the issue:

Before brightening:

After brightening:

Why does this happen? Are the images not loaded properly, or am I simply not using the class correctly? Here is my code:

Java Code: ...

RescaleOp op = new RescaleOp(1.2f, 0.0f, null);
op.filter(enemies.get(y).getImage(), enemies.get(y).getImage());
... mh_sh_highlight_all('java');

Swing/AWT/SWT :: Setting Size Of JFrame

May 26, 2014

I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.

import java.awt.FlowLayout;
import java.awt.Font;
import java.awt.GridLayout;
import java.awt.Toolkit;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

Swing/AWT/SWT :: Setting Icon On JButton

Feb 23, 2014

Recently I have been working on an executable launcher. I tried to get the executable icons and set them on the JButtons. Still there are some problems. Here is a part of the code:

try {
button[i].setIcon(FileSystemView.getFileSystemView().getSystemIcon(new File(getConfig("path." + (i+1)))));
}
catch (NullPointerException ex) {
}

Here the getConfig() method is already defined to get a string in a "properties" file. However, the icons are very small and they don't fill the entire button.

How can the icon fill the entire button (for example, having a custom size of 48x48, or automatically filled the button)? The frame will not be resized.

Here is the whole code...

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.io.*;
import java.io.File.*;

Recursive Implantation For Setting Objects

Apr 8, 2015

I have a requirement where I have a class as Page which itself contains ArrayList<Page>.Here ArrayList<Page> is nothing but the pages which are accessible from the base Page.I know the depth level ( reading from file) which means how many level I need to go to identify more pages.BUT the problem is how to set the base Page class. I need to set the base Page class but for that I need the objects for the subsequent pages and hence an iterative type of implementation.

JSF :: Binding Components And Setting ValueExpression?

Dec 19, 2014

dynamically create tabs by pressing a button, each tab has Primefaces input texts in which i'll be adding stuff and with a Submit button i'm submitting the form.

My issue now is this; although I can create more buttons through my managed bean, I cannot set the ValueExpression to the InputTexts. When I do:

inputName.setValueExpression("value", createValueExpression("#{cdiBean.name}",String.class)); it doesn't work.

The createValueExpression is a static method in my managed bean and it returns a ValueExpression. I'm most certain I found it online, not sure where though, it's been over a month since the last time I worked with this topic.

Anyway, is my whole "methodology" correct? Should I do anything differently?

RescaleOP - Setting Image Brightness

Aug 1, 2014

Is there any class which lets me set brightness to an image, preferably BufferedImage but it doesn't really matter, and then whenever desired remove the brightness. I have tried using RescaleOp, but it doesn't satisfy the latter criterion. When I have brightened the image, I can't seem to get it back to normal.

Java Code:

RescaleOp op;
if(image should be brightened){
float scales[] = {2f, 2f, 2f, 1f}, offsets[] = new float[4];

op = new RescaleOp(scales, offsets, null);
op.filter(getImage(), getImage());
}else{
float scales[] = {1f, 1f, 1f, 1f}, offsets[] = new float[4];

op = new RescaleOp(scales, offsets, null);
op.filter(getImage(), getImage());
} mh_sh_highlight_all('java');

Setting Left And Right Node Values

May 6, 2014

I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:

Node node = new Node("Is it human?", null, null);
node.getLeft().setNode("Is it Zelda?");//the first left Q
node.getRight().setNode("Is it Kirby?");//the first right Q

but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:

Node node = new Node("Is it human?", null, null);
node.setLeft(setNode("Is it Zelda?"));//the first left Q
node.setRight(setNode("Is it Kirby?"));//the first right Q

but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.

Here is my Node class:

public class Node {
private Node leftPt, rightPt;//left and right pointers for Node
private String node, left, right;
public Node(String node, Node leftPt, Node rightPt){
this.node = node;
this.leftPt = leftPt;
this.rightPt = rightPt;

Setting Up A Test For Combination Method

I'm having trouble setting up a test for my combination method.Here's the method (It basically finds the most amount of characters that both substrings share and combines the two using the number of shared characters as a breaking point):

public static String combination(String str1, String str2, int overlap) {
assert str1 != null : "Violation of: str1 is not null";
assert str2 != null : "Violation of: str2 is not null";
assert 0 <= overlap
&& overlap <= str1.length()
&& overlap <= str2.length()
&& str1.regionMatches(str1.length() - overlap, str2, 0, overlap) : ""
+ "Violation of: OVERLAPS(str1, str2, overlap)";
