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.
So I also am working on this problem. My frame does print each new rectangle; however, it is printed each time from the top left corner, and the bottom right is where I click.
Here is my RectangleComponent:
import java.awt.Graphics; import java.awt.Graphics2D; import java.awt.Rectangle; import java.awt.Shape; import java.util.ArrayList; import javax.swing.JComponent; public class RectangleComponent extends JComponent
I have a class that implements JComponent and draw a rectangle and if a key pressed(for example UP) I want to draw it up, and then when down key pressed to draw it down... But I want not only to disappear, but somehow to move, so the user can see the rectangle moving...
I have a problem here ive been trying to figure out and im not sure what the problem is. I have a JTabbedPane with an amount of tabs that match the amount in a JSlider. The amount can change dynamically.
What i want to do is have it so that if someone clicks the second tab it goes to value 2 on the JSlider etc... Should it be simple as adding a changeListener to each and going
So i was thinking about colors in java and was wondering what kinda colors are regonised by java..found this java.awt.color.. which goes very indepth with transparancy(alpha) and other formats of colors..
Question:
I wanne make a programm in java that breaks up a picture(pixels) and put it together again..Storing values of the colors and so forth..Which format of colors would be easy to start with if taking about java programming? RGB?
My assignment is for a game where there is a board of colors and each player draws a color and moves to that position on the board. It will then output how many cards total in the game it took whichever player to win. If no winner it outputs the number of cards that none won by going through. I attached the file that corresponds with my code.
This is the desired output:
Player 1 won after 7 cards. Player 2 won after 8 cards. No player won after 8 cards. Player 2 won after 4 cards. No player won after 6 cards. Player 2 won after 8 cards. Player 1 won after 4 cards. Player 2 won after 8 cards. Player 1 won after 1 cards. No player won after 200 cards. Player 4 won after 100 cards.
import java.io.*; import java.util.Scanner; public class ProgrammingAssignment1 { /** * @param args the command line arguments */ public static int players; public static int cards; public static int boardlength; public static String board;
[Code] .....
The output that I get is:
Player 1 won after 3 cards. Player 2 won after 8 cards. No player won after 8 cards. Player 1 won after 3 cards. No player won after 6 cards. Player 2 won after 8 cards. Player 1 won after 3 cards. Player 2 won after 8 cards. Player 1 won after 1 cards. No player won after 200 cards. Player 4 won after 100 cards.I guess I'm supposed to set the playerPos[] to -1, but I'm unsure how.
I need to write an image to a .png with a 255-color indexed color model. I know usually do it like this: Java Code: BufferedImage img=new BufferedImage(width,height,BufferedImage.TYPE_BYTE_INDEXED,model); mh_sh_highlight_all('java'); but that doesn't work with models with 255 colors (as opposed to 256 colors). I'm fairly sure it is the BufferedImage creation that is the problem, as when I call model.getMapSize(), it returns the correct size.
The extra color added to the image's index is 15,15,15.
Should I be something other than a BufferedImage to write the image, or should I be using a different constructor for BufferedImage, or am I doing something else wrong?
I have a program I wrote long ago. I change colors of buttons at times. Here is the code:
for(int Player=0; Player < 8; Player++){ //make them all background dealerLabels[Player].setBackground(new java.awt.Color(212,208,200)); } //Now make the new dealer green dealerLabels[dl].setBackground(new java.awt.Color(51, 255, 0));
The color of the buttons has always changed under XP but when I run the program on Windows 8 only the edges of the buttons change.
I have a question about JTextArea colors. When i set the color to blue and then write something on the JTextArea (JTextArea.append) and then set it back to black everything will be black. How can i solve that? Like in Notepad++ or Eclipse when you write keywords in a JTextArea (where you write your code) only some words change color.
This is my code:
// All the imports public class whatever extends JFrame { JTextArea a = new JTextArea(); public whatever() { super("Title"); add(a);
After generating a. JAR with Netbeans Java, when I play I see the colors of the components, the design and formatting is lost and the form gets a very basic formatting, for example, if I set a button with the color [0, 40.255] and build the. JAR after this, when I run the. JAR this button turns gray, and it happens with all the layout of the form.
I have a 30 X 10 JTable which i would like to put a border around some cells and change Background colors on others.For example i would like to put a border around cells 1,1 to 15,1 I would like to change background colours on several individual total cells.What the shortest way to color individual cells and add a border?

so i'm supposed to create a jframe with only 1 button. each time you push the button it is supposed to go from red to green to blue to gray and back to red starting over. i can get is the background to change on the first click, then the button is useless for eternity. here is my code:
import java.awt.*; import javax.swing.*; import java.awt.event.*; public class Exercise2_59 extends JFrame implements ActionListener { JButton change;
I'm writing an ESP game code for class. The problem is i cant get it to cycle through the colors after each guess is entered. It stays fixed on the original random number generated.
import java.util.Random; import java.util.Scanner; public class Final1 { String colorInput, computerColor; int computerNum, right, wrong;
[Code] ....
This repeats 10x but the color never changes from the initial random chosen.
I have a jtable , a customtablemodel and a customcellrenderer with the NetBeans IDE. I want to have different colors for different rows. But anytime I run the application , the rows are not painted as expected. The code snippets are provided below.
public class CustomTableCellRenderer2 extends DefaultTableCellRenderer{ @Override public Component getTableCellRendererComponent (JTable table, Object obj, boolean isSelected, boolean hasFocus, int row, int column) { Component cell = super.getTableCellRendererComponent( table, obj, isSelected, hasFocus, row, column);

This is from the Table Model.
public class DuesTableModel extends AbstractTableModel implements TableModelListener { private List<List<Object>> dataList = new ArrayList<>(); private String[] header = { "ID"," PAYMENT YEAR" , "AMOUNT"}; // Payment year is a date datatype private int minRowCount = 5;
I am making a quiz in Java. I need to be able to add images and colours into my quiz, to make the GUI look more appealing. At the moment, the JOptionPane that I am using looks very plain and boring. I want to be able to have my quiz running the same as it is at the moment, but I want to be able to import the images, add colours, and add Here is a copy of my quiz code:
I created a GUI with NetBeans. When I run the program in XP and the program changes the button colors, the whole button changes color. In this case, from "background" to "Green".When I run the program under Windows 8 only the border of the button becomes green.
NetBeans seems to use the Look and Feel "nimbus". I single stepped through the program on both computers and it looks like a request for nimbus does not cause an exception on either computer.
I was working on this project, and I have everything working, except that it doesn't change the colors of the shapes in the other window. Here's the code to see what I'm doing wrong:
Java Code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class JDemo { //Global Variables static Color color0 = Color.blue; //sets the value in the color0 variable to the method Color.blue . static Color color1 = Color.red; //Sets the value in the color1 variable to the method Color.red .
[Code] ....
The button0 is supposed to switch the color in window1, and button1 is supposed to switch the color in window0.
We have developed a theme called default.css that is extending of the default caspian.css. What we want to do is offer users the ability to override values from default.css to change colors etc. How can that be done?
I am trying to write a TreeMap that can hold a max of 20 colors and a minimum of 8. I have a while loop using pollLastEntry to limit the max but I can't figure out how to set the minimum. The hex number is the map's key and the color name is the value. I tried to use entrySet() and iterator to just double the size of the map but map can't have multiple keys with the same value. It also seems that to set a minimum would require some kind of further input(which I'm trying to avoid) of colors and their hex numbers.
//Method to hard code the colors into the map public TreeMap<String, String> cm() { //Color Map <Hex number, Color name> //Uses a TreeMap to keep all the colors organized by key TreeMap<String, String> cMap = new TreeMap<String, String>(); cMap.put("FFFF00", " Yellow");
Thats my code, and the rectangle (ObstacleX is the X cordinate for the rectangle) goes fine on the first few times across the screen, then starts to go hyperspeed....
I have to do the following: A bounding rectangle is the minimum rectangle that encloses a set of points in a two-dimensional plane. Write a method that returns a bounding rectangle for a set of points in a two-dimensional plane, as follows:
public static MyRectangle2D getRectangle(double[][] points)
The Rectangle2D class is defined in Programming Exercise 10.13. Write a test program that prompts the user to enter five points and displays the bounding rectangle's center, width, and height. Here is a sample run:
Enter five points: 1.0 2.5 3 4 5 6 7 8 9 10.The bounding rectangle's center (5.0, 6.25), width 8.0, height 7.5
This is my code so far, taking in account that Rectangle2D is already done in a previous problem.the thing is that i don't know if i have to erase public static void or do i leave it or how do i start it?
package theboundingrectangle; import java.util.Scanner; public static MyRectangle2D getRectangle(double[][] points) public class TheBoundingRectangle { public static void main(String[] args) { // TODO code application logic here } }
in order to speed up my application I want 'paintComponent(Graphics g)' to only write the visible area in my viewport. I can not find how to get that Rectangle from my JScrollPane.
