I am currently trying to make a method to make a resizable house. While I can certainly resize the size of every object in the house, for example a window, door, or roof, that has proven very difficult due to balancing issues(having a big window can overshadow the entire house). What I would like to do is resize all objects together at the same time so everything is spaced out accordingly. I imagine I will need some sort of mathematical formula to do so(which I am horrible at). Here is the method for drawing the house and the implementation of it.
Java Code:
public void drawhouse(double sizeH, double sizeW,double xpos, double ypos) { GRect body = new GRect(sizeH, sizeW); // w/2 h/3 body.setFilled(true); body.setFillColor(Color.GRAY); add(body, xpos, ypos);
[Code] ....
Ideally I wish I could just save all these objects into one (like creating a GObject and just calling that when I would want to edit it, but that has proven unsuccessful)....
ava Code: robot.keyPress(KeyEvent.VK_SHIFT); robot.keyPress(KeyEvent.VK_SEMICOLON); mh_sh_highlight_all('java');
And neither seem to work, in fact I can't seem to get any symbols typed out (I don't want to copy to clipboard and paste out) (yes, I do keyRelease as well -> I've tried a bunch of stuff)...
If I do try to do ChatFrame.setResizable(false); it gives me this error:

Write a program to simulate the operation of a simple robot. The robot moves in four directions: Forward, backwawrd, left, and right. The job of the robot is to move items and place it in the right slots in each station. There are 8 stations plus the pickup station. Pick up station is the initial start where the robot picks the items. 8 items can be placed on each station. The nearest station must be filled before placing items on the next station. The items are marked with identification or serial numbers. The items with odd serial number go to the right and items with even number go to the eft. The last slot, number 7 is reserved for light items which are less than 80kg. The serial number is a five digit number, the MSB digit 5 indicates that the product must be placed in the fifth station which is keeping the product at 20 degree F.
I am designing a game that simulates a roomba robot vacuum and have most of the framework done. So I have random floating circles and the Roomba bot in the center. The boot is suppose to move with the arrow keys. However when i run the program and select the keys nothing happens. Here's my code.
import java.awt.*; import java.awt.event.*; import java.awt.geom.Ellipse2D; import java.awt.Graphics; import javax.swing.*; public class Roomba extends JFrame implements ActionListener, KeyListener{
I am trying to make a calculator using Java GUI. I've managed to make an ActionListener and add it to a button, but I've made an error in my code that I'm unsure of how to solve. Because of how I've written the code, only one number can be placed in the text field. For example, the an ActionListener for the three button on the calculator was added to the button, but no matter how many times the user presses the button, only one 3 will appear in the text field. The code is below:
import javax.swing.*;//import the packages needed for gui import java.awt.*; import java.awt.event.*; public class Calculator { public static void main(String[] args) { JFrame window = new JFrame("Window");//makes a JFrame window.setSize(300,350);
[code].....
As you can see, because the compiler forces the String variable to be final, so when the user presses the button, the code simply shows how a space character and three character would look like, because the String variable can't change. How do I write my code so that every time the user presses the button, a character is added to the text field?
I would like to make a database using HTML and Java. I already made something like this using swing. I am just looking for some pointers here. I just started looking into Java Play 2 and I have a feeling this is what I am looking for. JavaEE is very complicated and I have read that it is being phased out. What is your opinion on this?
I want to make a static HTML page and put it on my home network and treat one of my computers as the sever accessing mySQL.
I want a completely unique GUI with unique buttons, like I could make it a giraffe if I wanted to! (not going to, but a giraffe seemed like a pretty irregular shape) ....
One of my assignments was to make a program that would read a sequence of names and then list them all.Just to be clear, it would read them all first, and then it would list them all at the same time.
i am trying to make a platform game in java and to do this im trying to make a scrolling bacground. i can get the background image to scroll. However, i cant get the image to scroll forever, here is the code.
GamePanel class ( the jpanel ) public class GamePanel extends JPanel implements ActionListener{ static ArrayList<BackGround> store = new ArrayList<BackGround>(); public GamePanel(){ setFocusable(true); Timer time = new Timer(5,this); time.start(); store.add(new BackGround(0,-200));
the problem i have is that i want the bacground to loop. however, once the first instance of the background is done scrolling it freezes and doesnt load anymore. here is the code for adding a new background to the list
so recently i made an applet and i was gonna put it up on my website when i got an error saying that java had blocked the applet duo to security thingys..sooo i looked in to it and i found out that apparently you need permission from java to run a applet or something like that, because there was a lot of viruses coming from there or something...
so does that mean only big game company's that can actually get permission by java make applets? are applets dead!? is there no other way to play java games in a browser!??!

I want to create simple java application which has 3 text fields and the application will have database connection. Once done, I want to run this application on other systems without using any IDE. So how do I do this? How can I make an application installable on other system so that on clicking on it, it will start executing?
I am trying to make a java Simon game but I cannot figure out how to make the GUI work. I have this so far, but now it just keeps saying I lose and it isn't functioning. It seems the only way I can make it work is having the action listeners in the do loop, but then once a button is clicked, the code errors out.
Here is an example of a GUI. Is it possible to make this kind of a thing using Java Swing? Is it possible to have a picture on the entire background of the JFrame, and then other Swing components like buttons, labels etc. sitting on it?Is it possible to have action listeners behind pictures? In other words, they will behave like buttons: the user clicks on them and they do something.
I am having trouble figuring out where to put %.2f in my code. I need it to get my answers for surfaceArea and Volume to be rounded to two decimal points. I have everything completed but wherever i put it, it seems to not work.
System.out.println("This program will compute the volume and surface area of a rectangular prism."); String output; double length; double width; double height; double volume = 0; double surfaceArea = 0; System.out.printf("%.2f", surfaceArea);
I'm having problems with the public static void main(String args[]) part. Everything else is correct before this, my teacher has checked that. I have been trying to research why it won't compile right and can't find any errors.
