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);

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?
Is it possible to put Jlabels in to a grid Layout on a Panel in a Jinternal frame

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.
panel_playerCards.setLayout(new GridLayout(2,10, 0, 0));
for(int i=0;i<9;i++){
StretchIcon icon=new StretchIcon(UnoGui.class.getResource("/UnoColors/green/card10.png"));
btnArr[i].setIcon(icon);
btnArr[i].addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
}
});
How to change the location of a grid bag positioned component after it's already been added to the layout earlier?
Example is if I want component 1 to change from row 1 to row 2.
I want to add only one button in a JFrame by using Mig Layout, dock south as BorderLayout.South does . Is it possible?

textio is used instead of scanner for our class.

Ideally I should be able to put in a number outside the range and the program will do nothing until I put a number in with the correct value.
I know that Servlets are meant to do the JDBC tasks, JSP are only for displaying the final information forwarded by the Servlet.
JSP are Servlets too, but I heard an idea that it is safer to make database operations in a Servlet.
The idea is that I have a few JSP that use JSTL tags to retrieve some database information. By doing this I was concerned that this may be bad design, though I really wanted to get in fit with the JSTL tags.
Are there any security weaknesses if doing some JDBC stuff in a JSP, by using JSTL or plain Java code in <%...%>?
P.S. In my JSP I only retrieve data, not modifying it.

The following code uses a column constraint to specify that a column of labels should extend horizontally in their cell but they don't as you can see by looking at their border. My mistake or a bug?

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.
View Replies View RelatedThe 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:
..*..
.***.

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.
import info.gridworld.actor.*;
import java.util.ArrayList;
import info.gridworld.grid.Location;
import java.awt.Color;
import javax.swing.JOptionPane;
[code]...
Now, let me narrow down the issue. It is in the runner class:
world.setGrid(new BoundedGrid<Actor>(world.getLength(),world.getWidth()));
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.
I am making a RTS game in Pure Java, and no libraries. So pretty much I want a constructor like so
Java Code: new Grid(40, 40) mh_sh_highlight_all('java');
That will create a 40x40 grid of a certain size per cell. Then I would like to fill the empty cells, and also be able to place things on top of them.
Also, I would like a tilt similar to Clash of Clans. How do I do this?
Working with some code that displays the random movement of an object such as Move 1: (0,1) Move 2: (10,99)?
I need these methods in the class
void initialize( int xPos, int yPos)
void moveLeft()
void moveRight()
void moveUp()
void moveDown()
int getXPosition()
int getYPosition()
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.
private int a1,a2,a3,a4,b1,b2,b3,b4,c1,c2,c3,c4,d1,d2,d3,d4;
public void getGrid ()
{
System.out.println();
System.out.print ("Enter Row 1: ");
a1 = i.nextInt();
a2 = i.nextInt();
a3 = i.nextInt();
a4 = i.nextInt();
System.out.print ("Enter Row 2: ");
b1 = i.nextInt();
b2 = i.nextInt();
b3 = i.nextInt();
b4 = i.nextInt();

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.
