Swing/AWT/SWT :: How To Return Values From A JForm To The Main Window On Close
Jan 26, 2014I am making a java swing program. I have a main window that opens a JForm window when the user clicks a menu option. Then I have a button on the JForm that closes the window on click. However, I would also somehow like to make the JForm return values to the main window (according to the states of the selector components) when it is closed. How would I go about this? Currently my jForm is a seperate class called "NewGame", and inside the menu item mouse clicked method, I have the following code:
//open new game jform window
NewGame newGameWindow = new NewGame();
newGameWindow.setVisible(true);
newGameWindow.setLocationRelativeTo(null); //center window
Is there something I can add here to get the object's values upon the window's close? Or is there a way I can add that into the button clicked method on the actual jForm?
How To Return Values In Object Return Type Function (method)
Apr 2, 2014How do i take input values for TwoDPoint (which are objects) and return it back in numerical values also print them.
When i create an object in main method and pass values to my function of return type TwoDPoint,it gives error:- found int,int need TwoDPoiint,TwoDPoint.
// Here is what i tried to do:
Created class TwoDPoint that contains two fields x, y which are of type int. Defined another class TestTwoDPoint, where a main method is defined.In the main method created two TwoDPoint objects.
Then I modified the class TestTwoDPoint and add another function to it. This function takes two TwoDPoints as input and returns the TwoDPoint that is farthest from the point (0,0).
Then I added another function to TestTwoDPoint. This function takes two TwoDPoints as input and returns a new TwoDPoint whose x value is the sum of x values of the input TwoDPoint's and whose y value is the sum of the y values of the input TwoDPoint's.
class TwoDPoint {
int x = 2;
int y = 4;
}
class TestTwoDPoint {
public static void main(String args[]) {
TwoDPoint obj1 = new TwoDPoint();
System.out.println(obj1.x);
System.out.println(obj1.y);

Swing/AWT/SWT :: Factory Design Pattern With Swing JDialog
Jul 26, 2014Is it a good idea to use the factory design pattern for say if I needed to create four different JDialogs for the same parent frame?
factory design interface
package client;
public interface Dialog {
void getInstanceOf ();
void initComponents ();
}
One of the four JDialog class would look something like this without the comments.
package client;
import javax.swing.JDialog;
@SuppressWarnings("serial")
public class AddCustomerDialog extends JDialog implements Dialog{
public AddCustomerDialog () {
//Some stuff goes here to set the settings for JDialog instance
[code]....
Of course you would have your factory class

May 16, 2014Lets say the JDialog opens 5x5. The user is allowed to modify its size to be any size larger than 5x5 but is not allowed to make it smaller. Is there such a property or will this have to be regulated via code?

Mar 30, 2014I have a practice exercise here wherein I will add a JOptionPane to a program. When the close button is clicked, the JOptionPane will appear asking the user to exit the program. If the user clicks "Yes," it'll, of course, close the entire program and not just the JOptionPane, but if the user clicks "No," it will return to the program. Please refer to my code below:
try
{
output = new DataOutputStream(new FileOutputStream("ProjSixExe4.dat"));
}
catch(IOException ex) {
this.dispatchEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING))
}
final JOptionPane optionpane = new JOptionPane("Are you sure you want to quit
this program?", JOptionPane.QUESTION_MESSAGE, JOptionPane.YES_NO_OPTION);
this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
The exercise said it must be placed before the EXIT_ON_CLOSE portion.

Neighbors Of 2D Array - Return SmartArray With Values
Feb 2, 2015I have attempted on my own many times but I am not getting any closer to a solution.
/**
* Returns a SmartArray with eight values. The values are the values stored in the 8 neighbors of the array cell at the given location in the Smart2DArray.
* Start with the neighbor to the "north" of the given cell and proceed clockwise, using -1 as the value if the neighboring cell is outside the Smart2DArray.
For example, if the array is:
1 2 3
4 5 6
7 8 9
neighbors(1, 1) should return a SmartArray with the values:
2 3 6 9 8 7 4 1
in that order.
neighbors(2,1) should return a SmartArray with the values:
3 -1 -1 -1 9 8 5 2
in that order.

public SmartArray neighbors (int col, int row) {

Calculate Distance Between Two Points - All Numbers And Return Values Should Be Of Type Double
Jul 8, 2014Write method distance to calculate the distance between two points (x1, y1) and (x2, y2). All numbers and return values should be of type double. Incorporate this method into an application that enables the user to enter the coordinates of the points.
Hints:
- The distance between two points can be calculated by taking the square root of
( x2 - x1 )2 + ( y2 - y1 )2
- Use Math class methods to compute the distance.
- Your output should appear as follows:
Type the end-of-file indicator to terminate
On UNIX/Linux/Mac OS X type <ctrl> d then press Enter
On Windows type <ctrl> z then press Enter
Or Enter X1: 1
Enter Y1: 1
Enter X2: 4
Enter Y2: 5
Distance is 5.000000
Type the end-of-file indicator to terminate
On UNIX/Linux/Mac OS X type <ctrl> d then press Enter
On Windows type <ctrl> z then press Enter
Or Enter X1: ^Z
Method Must Return Int Type - If Given Integer Is Strong Return A / If Not Return B
Sep 7, 2014I want to use a method, which takes for example an int and also returns an integer. For example, if the the given integer is strong return a, if it is notstrong return b. How would you write that in a Code?
I want to use that in a more general way. I want to give a method mlong the value X of the type date and let it return an int. Type date consists of 3 int, one of them is the int month.
mlong should return an int depending on the X.moth. at the moment my code looks like this:
// File1:
public class date {
public int day;
public int month;
public int year;
}
// File 2:
public class monthlength {
public int mlong(date X) {
int t;
t = X.month;
if (t == 1 || t == 3 || t == 5 || t == 7 || t == 8 || t == 10 || t == 12)
{ return 31; }
if(t == 4 || t == 6 || t == 9 || t == 11)
{return 30;}
}

Swing/AWT/SWT :: Rotating Buffered Image And Then Return It
Mar 7, 2010I wanted to write a method which gets a buffered image as parameter, rotates it 90 degrees clockwise around its top left corner, and then returns it. This method will be call from another method which then draws the rotated image on a rather large background which consists of many other images.
Here is the code I have so far:
public static BufferedImage rotate(BufferedImage img) {
int w = img.getWidth();
int h = img.getHeight();
BufferedImage newImage = new BufferedImage(width, height, img.getType());
Graphics2D g2 = newImage.createGraphics();
g2.rotate(Math.toRadians(90), w/2, h/2);
g2.drawImage(img,null,0,0);
return newImage;
}
This method does rotate an image 90 degrees, but when the calling method recieves this image and displays it on the bigger frame, parts of the rotated image is cut. I think because the frame holding the returned image is not big enough. I've tried playing around with the code a lot, chaging the sizes of different images, and trying AffineTransform features, but I have had no luck.
