Am stuck in a problem that asks to write a program using nested for loops to draw a V-shape of height "n" entered by the user with stars .

View Replies View RelatedI'm very new to Java, and I am creating a program that takes multiple user input to create one face. I have a class for the eyes, nose, lips, and headshape. For some reason, my program is not drawing the graphics. ***for question purposes, I have only included my head shape class and my test class****
my "test" class:
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class FaceTest
{
public static void main(String[] args)
{
String head = JOptionPane.showInputDialog("Would you like a circle, square, rectangle shaped head?: ");

I want to delete the shape i have drawn on the panel. Here is my code
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.geom.Rectangle2D;
[Code] ....
Why it is not deleting my rectangle.
So I've got this class method:
private void createTextBox() {
Graphics g = Game.getG();
Font font = new Font(fontName, fontStyle, fontSize);
g.setFont(font);
height = BORDER_WIDTH*2 + g.getFontMetrics().getHeight();
int stringWidth = g.getFontMetrics().stringWidth(dialog);
width = BORDER_WIDTH*2 + stringWidth;
[Code] .....
This gets called when ever I want to create my Textbox object however what gets created is a purple box (i know that I have set the array elements to purple to begin with) however when I try to use the drawstring method to "draw a string" I get an image which looks like the gif below. I have changed the text size to various sizes but without success. The string is supposed to say "This is a test" but obviously it doesn't.
I'm currently trying to do a diamond using Polygon. I have done this so far. It is not drawing a diamond.
import java.applet.Applet;
import java.awt.Graphics;
public class Diamond extends Applet {
int[] a = {-30, 100 , 30, 100};
int[] b = {100, 40, 100, -40};
public void init()
{
}
public void paint(Graphics g)
{
g.drawPolygon(a, b, 4);
}
I currently have the code set up to iterate through objects and keep track of them but how do I do the same and draw the objects on the panel window? I'm confused on what to do and how to start it.
Here's the code I have so far, the 'Car' which I want to draw extends to another class which extends to GameObject. I currently have a 'draw()' method under the 'Car' class but nothing in the 'draw()' method yet. From what I understand i'm suppose to have a 'draw()' method under 'GameObjects' class also?
public class MapView extends JPanel implements IObserver, ActionListener{
JPanel myPanel;
private Timer timer = new Timer(5, this);
int x = 0;
int moveX = 2;
public MapView(){
super.setBorder(BorderFactory.createTitledBorder("Map:"));
[code]....
Mostly I don't understand how to go through the iterator again to paint the objects. Wouldn't I need to put another iterator under 'paintComponent()' or can it be done under 'update()' ?
how to get some shapes from the GameObjects onto my panel.
one of the java swing challenge I am facing. Problem statement: there are two JPanels panel 1 and panel 2 placed on a JFrame one below the other as panel 2 below panel 1. Now, I need to put a JButton in any one of the panels such that this JButton displays half in panel 1 and half in panel 2.

Simple gui task. it meant to draw pie chart with different colors. i can't seem to find a mistake in it. It works if i put in g2g.draw(arc) i know arcs overlaps a bit due int conversion, but that's ok.

View Replies View RelatedI'm trying to code a little text RPG. I've made a little "personality test", with 4 questions (answers a b c), where every letter stands for a type of personality. The analysis of the result is simple counting of the answers, if you have 3 answers a (4 questions), then a has won. If 2 on a, and 2 on b, a simple Random method shows weather result a or b.
Now... the test should give you a "partner" (imagine the pokemon game with 3 different starter pokemon). I have now 3 string variables, like 3 different partners. They are all declared somewhere outside, but i only need one later.
Like...the test is completed, you have your partner and how can i make now that the program is just showing me my partner? Like...when i type " System.out.println(partner); " (outside of the test loop! ) that i only get the one i got through the test?
I was trying to declare in every loop the partner String with every result. But outside the loop java isn't recognising that String, bcs...ofc...it was declared for the loop. So i had in every if or else if clause a " String partner = anwsA;" and answB and answC, thats why i cant declare them outside.
Short: i need a partner String variable that could have 3 possible results... i jut need one

Then I loaded each Item data in to its object and fill a Jcombobox. Now I want to search with Item name and get all Item data when selecting that item.

1. I have to do web application.
2. Google not support 'without internet' map facility.
3. I should use lots of jpgs which store in folder for showing map from various height so it look like when we see any map in Google Earth application.

View Replies View RelatedI don't know if this is appropriate to Swing/AWT, or even if this is a Java issue, but I had quite a shock recently. I have been working on a kind of drawing program in which the user can select tiny control rectangles and drag them around, causing the shape of a polygon to change. (They are not implemented as Java Polygons or Shapes because some are one-dimensional). I have gotten it into pretty good shape, so I exported it from Eclipse, my development platform, into a standalone Java application. In the standalone application, each time I drag the mouse, the redrawing shows nasty flickering, as if it's running too slowly. While I was developing the application inside Eclipse, it ran perfectly, with no flickering whatsoever.
What gives? I'd expect that the in-Eclipse runs would be slower, because they're burdened with extra debugging baggage, while the exported standalone version should run faster. But the reverse is the case.
this code won't compile because selected row must be declared as final because of it being defined outside the window listener. Is their anyway around this? If I make it final the first time that the variable is called it keeps it starting value until the GUI is closed.

I am building a GUI application which consists of two panels "panel" and "panel1". "panel1" have a button "addTimer" when clicked it should add the "panel" to the frame if i gain click the button it should again add the "panel" without overlapping the previous "panel" rather it should be created below the previous "panel". If i click on the button "addTimer" n times it should add the panel n times. Along with this the frame size has to dynamically change depending on the number of panels produced. Below is the code i tried my level best to satisfy the above conditions.

I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.
