Trying To Print Array Of Image Icons
Aug 23, 2014
I am simply trying to print out a deck of 54 playing cards. i have organized them in to two separate arrays the first array to place all the image icons the second array to hold the 54 Jlabels. I think my problem lies in the setLayout portion of the program . I also think my image icon path may be wrong?
import javax.swing.*;
import java.awt.*;
public class CardIconArray extends JFrame {
private static final long serialVersionUID = 1L;
final public static int numberofcards=54;
CardIconArray(){

If you look at line 74 you will see my actionPerformed method where I want to switch the icon displayed on the JButton. I know I still have to add the images to the button however I am running into a few issues here.
In my next class it will be vital that I can decipher what each icon is display on the JButton.
Java Code: import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.event.ChangeEvent;
import javax.swing.event.ChangeListener;
public class Screen implements ActionListener

import java.awt.event.ActionEvent;
import java.awt.event.*;
import java.awt.image.BufferedImage;
import javax.swing.JFrame;
public class Golf extends JFrame
{
boolean isRunning = true;
[Code] ....
It loads and draws fine when I am using one image. But if I un-comment the others are try to draw the background of my game as intended, nothing gets drawn. I've played around with a number of different solutions but nothing works, I've had multiple images work in previous programs doing exactly the same thing and I really don't understand whats up.

Therefore my main question is, am I even approaching this problem correctly? In my next class it will be vital that I can decipher what each icon is display on the JButton. I am working on programing A* but I have to get everything talking first.

I wrote this code which print a black image depends on the number of rows and columns you give it
public class BlackImg {
private Mycolor[][] colorArr; //Mycolor is a class i wrote that represents colors.
// no need for showing the class here.
// so i created here an array of type Mycolor, for example:
// { {(255,255,255), {(127,127,0)} }
[Code] .....
my problem is that my output comes good except the last line ,
Output:
(0,0,0) (0,0,0) (0,0,0) (0,0,0)
(0,0,0) (0,0,0) (0,0,0) (0,0,0)
(0,0,0) (0,0,0) (0,0,0) (0,0,0)
BlackImg@1db9742 //what is this line , why does it showing up ?

So I have scale, and you can change it, like I print out a bufferedimage read by imageio from a file, can I enlarge it by 2x, because my tiles are too small eventhough they're 16x16, should I decided to decrease my tile grid from 40 to 20, but instead change the scale by 2. Can I enlarge the image as it is put on the screen?

I'm trying to print (to the printer) a small image 265x35 px and it is printed in very poor quality with jagged edges. When I'm printing it from any other program (e.g. Word, mspaint, etc) it is printed clearly.
Also, the image is printed bigger than it's normal size (approximately 25%). But, I'm not doing any scale in my code. I did scaled it down to the right size, but the quality still remained very poor and jadged.
The image is a transparent PNG file. I tried with a BMP too, but I got the same results.
I'm using
Graphics g;
g.drawImage(headerLogo, x, y, headerLogo.getWidth(), headerLogo.getHeight(), imageObserver);

I'm writing a program to print an ASCII image using nested for loops. The output is a rocket ship that looks like this.
/**
//**
///**
////**\
/////**\
+=*=*=*=*=*=*+
|../..../..|
|.//..//.|
|//////|
|//////|
|.//..//.|
|../..../..|
+=*=*=*=*=*=*+
|//////|
|.//..//.|
|../..../..|
|../..../..|
|.//..//.|
|//////|
+=*=*=*=*=*=*+
/**
//**
///**
////**\
/////**\
I'm having problems with the mid section of the rocket, specifically the bottom part of the mid section:
|../..../..|
|.//..//.|
|//////|
I'm having difficulty writing the for loop to correctly print the dots. You're supposed to incorporate a constant which allows you to adjust the size of the overall figure. The loop doesn't work when I adjust the size, only when the value of HEIGHT is 3. The loop, however, for some reason works with the top part of the mid section.
This is the for loop for the top section.
for (int dots = 1; dots <= -1 * line + 1 * HEIGHT; dots++) {
System.out.print(".");
}
This is the for loop for the bottom section.
for (int dots = -1 * line + 1 * HEIGHT; dots <= 1; dots++) {
System.out.print(".");
}
Usually reversing the iteration of the loop just requires flipping the conditions, right? But it didn't work this time for some reason. Why this doesn't work? I can post the code to my entire program for compiling.

I have double checked this code over and over and I just can't find the problem.
What I'm trying to do is take a file and input it into an 2D array.
Ultimately, I should convert the array of integers to an array of characters, then print it out. The file contains a set of ASCII values.
After printing it out, I should then create methods to manipulate the image produced.
Using 2D arrays is a requirement for this exercise.
I think that somehow I'm overcomplicating this and the solution is a lot more simple than I think, but I can't think of what to change.
The error I am getting is:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 40
at main.main(main.java:17)
Java Code:
import java.util.*;
import java.io.*;
public class main {
public static void main(String[] args)
throws FileNotFoundException {
String[][] data = new String[22][40];

I just tried to fill an array with some numbers, calculated by a other function.I just tried to print this array as array, but it doesnt work. Maybe its just about the main method.
public static void main(String[] args) {
ggT(5);
}
public static int ggT(int a, int b) {
while(a!=b){
if(a>b) {
a=a-b;
} else {
b=b-a;
}
}
return a;

I created an ant script to create an installer for my JavaFx app:

<target name="init-fx-tasks">

During compiling I see:
Using base JDK at:
/Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk
Using default package resource [Bundle config file] (add package/macosx/Info.plist to the class path to customize)

Use them to customize package.
fxbund
ler/macosx. Use them to customize package.
So I get files inside the temp directory and I copied them inside my project target directory. Unfortunally javafxbuilder don't use them to customize the package so I think the path where I have to put that files is wrong.

I'm using a jpanel with an 8 by 8 grid layout of jlabels to which I'm adding images to represent a chess board. At first, I was using the ImageIcon class to initialize my icons, but as soon as I added these icons to the labels, the labels no longer changed size with the window (which I want to happen). URL...
So I copied in the class, and initialized a different set of icons using the stretch icon class (specifically, the method that allows you to initialize a stretch icon from a filename), however, when I use these stretch icons, the result is the same. Is something wrong with the class, or with my implimentation of it, and how would I fix this?

I'm trying to create a chess program in java swing, and for the board I'm using an 8 by 8 array of jlabels stuck inside a jpanel with a grid layout. I would like the board to change size when the window changes size, and the grid layout accomplishes this succesfully, until I add the actual icons to the jlabels. Then the board just stays a fixed size. Someone suggested I use their "Stretch Icon" class, found here:[URL] ...., so I tried initializing the icons using one of the constructors in the class (the one that takes an image name and a boolean value for whether or not you want the resisizing to be proportionate (to maintain the aspect ratio)). However, the same thing happened. The board appears, but it does not resisize. To attempt to fix this problem, I tried simplifying my code, reducing the program to two jlabels within the jpanel, for which I then tried to set the image in the same way. Here is my simplified code:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.ImageIcon;
[Code] ....
I'm misusing the stretch icon class, or just generally what's going wrong/how to fix it?

I am working on a simple app that should emulate a desktop with some icons that you can drag around. I was instructed to use the MouseListener and MouseMotionListener. The icons should drag starting at the point where the mouse originally clicked down on it (ie not dragging from the top right corner).
I am drawing my icons to a jpanel, and I seem to be having two problems:The hitboxes are offThe icon is being dragged from the top right corner, despite having setup up a mouse offset at the beginning of the drag..Here are the relevant classes, the Desktop.draw() method is being called from my DrawPanel

I am trying to process an array of pixels, checking each within a 5*5 mask. Ive declared my mask as a 2d array and get the pixel values within a nested for loop. Im getting an ArrayIndexOutOfBoundsException at the line:
mask[0][4] = dsIm.red[i-1][j+3];
Have I declared my mask wrong for a 5*5 mask. Is my logic wrong?
I won't give all the code, but basically Im trying to check all 25 pixel values within the mask:
int [][] mask = new int[5][5];
System.out.println("We are in the method just written");
//loop one loop
for(int i = 1; i <= h-2; i++)
{
for(int j = 1; j<=w-2; j++)

Designed to store a first name (string), last name (string), and zip (int). Assume each line will contain two strings followed by integer each separated by tab. Then print.
I have my two class files (one for the individual and one for the array) and then my driver below. I think my only problem is my driver. I think I'm reading the data file wrong but not sure how exactly.

So i wanted to try something new like find an image within an image. So for my "find" method I would like to take an image and use it to scan and compare sum of absolute differences with the bigger image. So that the smallest SAD would be the exact image that I am using to scan. What I am thinking is to put each pixel value of both images into two separate arrays and compare them via Math.abs(image1[i][j]-image2[i][j]); . My only problem is that I do not know how to put each pixel value into an array.
Also, If I only want to compare just the green in the picture. I saw that the Pixel class has a getGreen(); method. If I want to find the SAD of the green, would Math.abs(image1.getGreen()-image2.getGreen()); work? I was planning to have 2 nested loops running through each column and row for each image and just find the SAD of the green value.

I am trying to get this program to take 5 integers from a user and print a bar chart made of asterisks. The only way I've been able to access the values stored in the array is when my loops are nested, but this keeps my output from printing the way I would like it to.
It prints:
Enter a number:
2
**
Enter a number...and so on
I want it to take the values say(2,3,5,8,4) and do this:
**
***
*****
********
****
public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner in = new Scanner(System.in);
int[] barArray = new int[5];
for(int i =0; i < barArray.length; i++){
System.out.println("Enter a number: ");
barArray[i] = in.nextInt();
for(int j = 0; j < barArray[i]; j++){
System.out.print("* ");
}System.out.println("");
in.close();

This code is not best way to find the duplicate elements in a given array. Any alternative method for an optimized code.
Java Code:

int[] Array1 = {1, 9,8,1,2,8,9,7,10, -1, 1, 2, 3, 10, 8, -1};
// Store the array length
int size = Array1.length;
//Sort the array

Thought process : Sort the array and print the last 2 element of any given array.
Note /| Should not use any inbuilt Array.sort()
Java Code:
//Write a code to print the 2 largest numbers from the given Array {2,8,10,5,9}

I am having an issue trying to print different types of arrays using one method. Eclipse tells me to convert my print method for each array type:
change method 'printList <e>' to 'printList(ArrayList<integer>)'
change method 'printList <e>' to 'printList(ArrayList<Double>)'
change method 'printList <e>' to 'printList(ArrayList<Character>)'
change method 'printList <e>' to 'printList(ArrayList<String>)'
I would like to accomplish printing all four different arrays using one print method. How to accomplish it or provide examples or links to examples?

I'm trying to pass an integer array,
int[] fibSequence;
From my Fibonacci servlet to a jsp page called "result" but when I pass the array in the redirect I get the following output:
[[I@63cf2179]
I figured out that this is because the array is being converted to string before it is passed over and then converted again on the jsp page.
How I can pass the array over and print the contents, ie an array of integers?
This is how I'm sending the array in the result page:
resp.sendRedirect(("result.jsp?fibSequence=" + fibSequence));
And this is how its being retrieved and printed on the result.jsp page:
<%String[] fibSequence = request.getParameterValues("fibSequence");%>
<input type="text" name="fibNum" value="<%=java.util.Arrays.deepToString(fibSequence)%>" size="40px" style="font-size:30pt;height:60px">

An array which contain a list of names. I let for a user input and I use that to search through the array. For example lets say the string name "Christian" is stored inside the names array and the user types in Chri, the program looks in the array and finds a name that contains Chri and prints them out. How do I go about doing this?
