the thing with this program is that instead of it having preset variables, I want to prompt the user to enter values of the two rectangles. I don't know how to use the scanner in this case, or even if I should use the scanner.
class MyRectangle2D {
//declare the variables
private double x, y;
private double width, height;

I have 4 small applets on a page that simply prints out the quadratic equation for values passed in. There are 4 applets on a page that have different values assigned. They display fine.... sometimes.... if I refresh or generate new numbers sometimes one applet looks as though it has numbers overlapping the new values. If I resize or drag the browser everything displays fine again - no need to refresh the browser or anything. It's as though old values or something are being overwritten by the new or something similar is happening. What should I include in the paint method of the JPanel that might clear the applet before initial painting happens..... if anything?
View Replies View RelatedWrite a program that draws 20 circles, with the radius and location of each circle determined at random...... Two circles overlap if the distance between their center points is less than the sum of their radii...
There may be many problems with the code in general but what I'm struggling with is the distance and the totalradius portion. Visually, its inaccurate.

My goal is to make 2 rectangles in the same window. so far I have this.

After running the program I get one rectangle, the red one. If I take the code out for the red rectangle, I only get 1 blue one. What am I missing?

The program is where you will click anywhere in the jframe and it will draw a new rectangle. I have altered the code given to us but the problem that I am having is the fact that when I click the rectangle will always be connected to the upper left hand part of the jframe, no matter where I click. The program should create rectangles of the same length and width wherever you click. Here is what I have. I believe I have to change something in the addRectangle method, but nothing that I have tried works.
Java Code:
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;
import javax.swing.JComponent;
import java.util.ArrayList;

I have already tried every possible way for removing this bug but all failed. The problem is that sometimes my player passes through the map tiles, i mean, the algorithm is like -- if not colliding, move in required direction; else if colliding, move in opposite direction. But sometimes the second condition fails i dont understand why.
private void movement(){
left=bindObject.getLeft();
right=bindObject.getRight();
up=bindObject.getUp();
down=bindObject.getDown();
bindObject.setColliding(colliding);
[Code] .....
Where bindObject is a class which contains key bindings of following keys:-
left arrow key (when pressed) , left arrow key (when released),
right arrow key (when pressed), right arrow key (when released),
up arrow key (when pressed), up arrow key (when released),
down arrow key (when pressed), down arrow key (when released)
I'm not exactly sure what the draw button is supposed to do specifically, all i know is that it is supposed to draw both rectangles and ovals. The problem I am having is that when ever I click Draw Rectangle, it draws rectangles jusst the way I want but when ever I click Draw Oval, the program keeps drawing rectangles. I've tried repaint and clearRect methods but I did not manage to get them to work. I'm not sure what the problem is right here, I just cannot get it to work. Is there anything you guys can see that might be causing this? It's always good to have a different person look at it then myself. Also, I'm trying to implement a boolean for draw oval but I don't know where to put the if then.
public void init() {
length = new JTextField(10);
width = new JTextField(10);
btnDraw = new JButton("Draw");
btnClear = new JButton("Clear");
btnDrawRectangle = new JButton("Draw Rectangle");
btnDrawOval = new JButton("Draw Oval");

I made a small aplication which draws 3 rectangles in different spots(0,0 , 50,50 , 100,100)
Am I used an KeyListener + ActionListener, to make them move in the let's call it box.
How can I do in order that those 3 elements do not cross, so you can always see them, they don't collapse into each other?
Java Code:
package matrixmoveelements;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;

I have a code to resize a single rectangle. I would like to display and resize multiple rectangles independently and according to my research on the net, the best way is to use an arraylist. So I modified the code in this sense, except ...when I run the code, the rectangles appear good but impossible to resize. I think the problem comes from mousePressed, Released, Dragged and Moved methods. When I use the mouse to resize the rectangle, nothing happens. The code does not interact with the arraylist, and therefore with rectangles it "contains". Resizing is my main class, the MouseAdapter is in the Resizer class (below).
Resizing component; boolean dragging = false; // Give user some leeway for selections.
final int PROX_DIST = 3; Path2D.Double selectedPath; public Resizer(Resizing rz) {
component = rz; component.addMouseListener(this);
component.addMouseMotionListener(this);

The following class is part of a homework assignment:
package event;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import model.Model;
import shapes.Rectangle;
import shapes.Shape;
[Code] .....
I have to implement the methods for what is happening if on some panel the action selected are Remove/Move/Change/Resize (Draw is already implemented).
The Applet in question draws ovals or rectangles on the screen and you can change the fill-color and outline-color of the shape. All this works already. I have dabbled with the move-method, but am not going anywhere.
So the following is my code for the Terrian Generation of my game, however the way i have it rendering all the tile rectangles as opposed to just rendering whats visable on my JFrame causes lots of lag.
These are the variables and Rectangles inside _TerrianGen.class
//CHUNK
static int chunkx =2048;
static int chunky =2048;
//RECTANGLES
public static Rectangle[][] tile = new Rectangle[64][64];
static int[][] blockType = new int[64][64];
//0=Grass 1=Dirt 2=Stone 10=Brick 11=Coal 12=Iron 21=Gold 22=Diamond -1=null
This is the Init() code
for (int x =0; x < chunkx-32; x+=32){
for (int y=0; y < chunky-32; y+=32){
tile[y/32][x/32] = new Rectangle(x, y, 32, 32);
blockType[y/32][x/32] = -1;
