How to implement GridLayout. In my applet, I want to make a grid of 2 rows and 2 columns. In each grid I want to add a Label and a TextField. I want the background to be red.
So my code would be?
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class GridLayoutApplet extends Applet implements ActionListener{
// construct components
Label fNameLabel = new Label("First Name");
TextField fNameField = new TextField(20);
[Code] .....
I have read about panels and frames but, it is all confusing to me. How can you add a label and a TextField to one square of the grid?
I am making a basic calculator using SWING.I want my JTextField to stretch across the top, above my buttons. All I can seem to get is it be the same size as one of my buttons.
import java.awt.GridLayout; import javax.swing.*; public class Screen { JButton start; JButton reset; JButton box[][] = new JButton[20][20];
[Code] ....
I am trying to place the buttons on the bottom. I tried a few different things but the grid layout keeps grabbing it and making them a part of the grid at the button.
Am trying to dynamically insert buttons (which will be presenting card in a frame) using grid layout.As shown image is getting inserted but its not fit in button.I tried Darryl's Stretch icon as well but of no support.
I am currently trying to write a method for checking to see if an "agent" in a cell (place in a 2d array) is satisfied. So, the assignment is a 2D array that can have a blank space, an O, or a X as a character that fills a particular space. An agent is satisfied if it has similar characters around it in a percentage that is higher than the threshold. For example, if the threshold was 60% and a cell that had an X in it, had 3 X's around it and 2 O's, then it would be satisfied because 3/5>=60%. For my code, I tried using if and else statements to isolate circumstances in the corner of the grid, the edges, and everything in between.
public static boolean isSatisfied(char[][] tissue, int row, int col, int threshold){ char check= tissue[row][col]; if (check==' '){ return true; } else{ int countx = 0; int count = 0;
So I'm making a calculator using JFrame and that stuff and I need figuring out the GridLayouts. I'm not doing this for homework or anything just for fun. I don't need all the grid layouts.
The point is to use a binary search to determine how many steps it would take to get to int X, int Y in a grid that is N by N. Picture a parking lot that is square and your car is at (x,y). You can honk your horn from your key to determine the direction of the car. I need to return the amount of steps to get to the car. You can't step diagonally. I am currently getting an error that causes an infinite loop and I can't fix it.
public class ParkingLot { public int search(int N, int X, int Y) { int minX = 0, maxY = N, minY = 0, maxX = N; int num = 0; int curX, curY; int newCurX, newCurY; curX = (minX + maxX)/2; curY = (minY + maxY)/2; while (curX != X || curY != Y)
I am new to java and i am trying to make a Java application which prints a diamond in a square grid of dots whose side length is input to the application.When you run the code is should be like this:
..*.. .*.*. *...* .*.*. ..*..
My java code print this:
..*.. .***. ***** .***. ..*..
Here is my code:
class Main { public static void main(String args[]) { System.out.println("#Enter size of Diamond :"); int longestRow = BIO.getInt(); for(int row=1 ; row<=longestRow ; ++row)
I wanted to know which RAD TOOL should I use to make the grid. I used the label but it's not interesting like the game *. I m starting to make the game and can't think how to make the grid.
Thought of using the buttons but can't add image to it.
what should I use to make the grid.
* what I did earlier Is place 9 label in grid form (just to test) and nine buttons one for each. When u click a button, image is shown in respective label... But it doesn't feel like u r playing game..
I have a question about updating a grid during runtime in GridWorld. I'm making a game called Flood-It (basically, you click on squares to change their color and attempt to get all of the squares the same color in the grid) and I'm having trouble with changing the grid size. I made my own world class, called CellWorld.
Whenever a user wants to change the grid size after playing the game, this is supposed to set the grid to the new updated size, but it never changes in the actual game, i.e. the user just won a 2x2 game, attempts to change the size to 10x10, but the grid stays 2x2. By debug testing, I can say for certain that everything else works, such as the maxStepCalc and loading the grid. The only issue is the new grid not showing up.
how to create coordinates in a two-dimensional grid, in the end it shall look like A5, F6 and so on. The aim is to place 3 DotComs in this grid by coincidence. To do this one uses two arrays. One array represents one DotCom, the other represents the grid's size, in this case 49 (7x7).The code ends like this:
ArrayList<String> alphaCells = new ArrayList<String>(); ... int x = 0; int row = 0; int column = 0; while (x<comSize) { grid[coords[x]] = 1; // mark master grid points as used row = (int)(coords[x] / gridLength); column = coords[x] % gridLength; temp = String.valueOf(alphabet.charAt(column)); alphaCells.add(temp.concat(Integer.toString(row)); x++; } return alphaCells; }
why row and column are calculated like this. Furthermore I don't understand why the column is used to generate a character, because columns are marked with numbers and rows are marked with characters.
I have a get grid method that gets input from the user. I also have a display grid method that is supposed to display the get grid method but it doesn't. What do I do to make the display grid method work properly. I am not allowed to use a main method.
i am to add jpanels to an arraylist such that it forms a grid like a 2d array. when i add the first colunm and have to iterate and store the next sequence of jpanels it still stores it in get(0), instead of get(1).
I am attempting to make a 5x5 bingo board. My array generates 75 numbers(15 per bingo letter) and displays them in a random order. What I am having trouble figuring out is how to fill the 5x5 grid with 25 numbers from my array. And yes, my code is probably much longer and much more redundant than it needs to be. Also, I think I'm using cells and grids terribly wrong (possibly the entire java language) but I'm not sure.
So I need to create a 10x10 grid for a snakes and ladders board, the board loads but i cant figure out how to add numbers to the squares. Here is my code :
import java.awt.*; import javax.swing.*; public class Board { //Creating the array int[][] numbers=new int[10][10]; public static int rows = 10; public static int columns = 10; public static Color col1 = Color.green;
I've been reading that there's no way of making a JLabel user writable. What can I use inside the grid to make it writable with a keylistener? I'm making a crossword.
I'm using JavaKara (a graphic Java software to learn coding) on my classes at the moment and we're asked to transform something like this:
In the inverse, where you can see clovers there must not be any and where there aren't you must plant them. PLUS YOU MUST SWITCH THE FIGURE HORIZONTALLY.
This is the result i should obtain:
public class InvertiECapovolgi extends JavaKaraProgram { public void myProgram() { boolean arrayquadrifogli[][] = new boolean[world.getSizeY()][world.getSizeX()]; //[rows][clumns]-->[Y axis][X axis] in kara for (int y = 0; y < arrayquadrifogli.length; y++){ // My Ladybug starts to run through the whole grid
[Code] ....
How to switch everything horizontally!
This is my result:
My ultimate question is, how do i have to edit the second loop, and why, to obtain the horizontally reversed result i'm supposed to obtain?
Currently, I am trying to create a program that draws a square anywhere in a 15x15 Quadrant I (Coordinate plane) grid. I am stuck on trying to get the axes displaying correctly. This is the code I have thus far:
import java.util.Scanner; public class Question2square { public static void main(String[] args) { // Axis variables int yAxismin = 0; int yAxismax = 15;
[Code] ....
Unfortunately, instead of drawing the 'L' shaped axes I desire, it displays an 'r' shape instead. I'm trying to figure out how to display the axis properly. I tried flipping the for loops but that didn't work. I don't see what else could be inhibiting this.
What would be a good and simple algorithm to find the shortest route between two points in a 2D array[grid] ? There can be certain obstacles in the grid i.e. some of the cells may be inaccessible. I tried googling for it and found that A* is the best for this but I am just a beginner and would like to start with something much simpler.
I am busy programming a clone of the popular phone game they had on Nokia cellphones a long time ago called Snake II but since I know very little about programming I will be using ASCII graphics instead of a 2D graphics engine.
My idea for implementation is having a main class called game which should refresh a grid of ascii characters every, say 0.2 seconds. Then I have another class called Dot. Each Dot object has x and y coordinates, and a direction in the x and y planes (dirx = -1 means left, dirx = 1 means right, diry = 1 means up, diry = -1 means down, and obviously the snake cant move the diagonals)
The Game class prints a "*" symbol where the Dot is, and what I'm trying to do is get the screen to refresh (I think I need to use the sleep() function for this to slow the game down to a reasonable pace), and go in the direction it is supposed to go.
(I haven't programmed this in yet but the snake will be an array of Dot, and at each refresh Dot at position 0 will pass it's coordinates and direction to Dot at position 1, Dot1 to Dot2, Dot2 to Dot3, etc.
Here's my code so far:
A first class called Game.
Java Code: //Not done yet but this is the start to my game of Snake. Basically the class Game generates a Grid of ASCII characters
import java.util.Scanner; public class Game { public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); final int WIDTH = 79;
[Code] .....
My problem now is that I am taking input from the Scanner class. What it does is wait for my input, then it goes on to executing the rest of the code in other words refresh the ASCII grid. This is a problem because I need the snake to keep moving at constant pace while listening to the keyboard.
How can I get my while loop to keep going (i will add a sleep() function later) while listening to the keyboard without stopping?
