Creating A Word Rectangle?
Nov 7, 2014
I was tasked with building a program that, when is given a string by the user, takes it and prints it out as a rectangle. For example, if the user types in "COMPUTER", the output would be:
COMPUTER
OMPUTERC
MPUTERCO
PUTERCOM
UTERCOMP
TERCOMPU
ERCOMPUT
RCOMPUTE
So far, I have created 2 separate strings, and have gotten the output to look like:
COMPUTER
OMPUTERC
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
OMPUTERO
So, it works once, but then it doesn't work again. Here is my code:

I was given the assignment of creating a number to word program for my first college java programming homework.
Here is what I have created so far :
import java.util.*;
public class PrintNumberInWord { // saved as "PrintNumberInWord.java"
public static void main(String[] args) {
int number = 5;
Scanner sc = new Scanner (System.in); {
System.out.println ("Enter a number");
System.out.println(" ");
if (number == 1) {
[Code] .....
The first lines were made for us so we could follow a guideline, however, no matter what I type the command prompt displays 5 to me, I know thats because 5 is defined in the beginning but backspacing 5 causes the program not to work at all, how can I get this program to work properly?

I have built a binary tree, from a file. In each node, I am storing each word as a string, and an int frequency for each time the word occurs. For the assignment, I need to find how many words occur only once in the file. I wrote the program, but for some reason I am getting a number different from what my professor is expecting.
As far as I know, this file has loaded into the tree correctly, because all of my other answers in the assignment are correct. What am I doing wrong?
public void findUnique() {
System.out.println("There are " + findUniqueWords(root, 0) + " unique words.");
}
private int findUniqueWords(Node subTree, int uniqueCount) {
// Base Case: At the end of the branch
if(subTree == null){
return uniqueCount;
[Code] ....

The intentions of this program is to prompt a user to enter a file name, and then reads the file. The program will prompt the user to enter a word that needs to be corrected. So lets say I have a text file containing "My name is OP and I Like goind to the Park!" I want to change "goind" to "going",
Now, my second method "isSimilar" executes a similar word with more than one same letter and same length, but I dont know how to execute that whole thing in my third method "correctThisLine" . How I can call that isSimilar method and read in that text file and change that word into that?
import java.util.*;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class WahidMuhammadA3Q2{
String fileName = "AutoCorrectMe.txt";
public static void main (String [] args){

I am looking for java codes to generate a word document based on a word template, basically, I have a word template created and in my local path, the template has a proper format with some fields which will be filled in after java codes ran. The java codes will fetch one record from a table, and open the word template and then fill the fields in the word template, and created a new word document and save it in another folder.
I found this example: [URL] which is similar except it uses xml template instead of word template, how to make it work to change the template from xml to word (docx) template?

Here's My Code.
package bin;
import java.util.Scanner;
public class AppletMain{
public static void main(String[] args){
Scanner oneinput = new Scanner(System.in);
String one;
[Code] ....
I am trying to get it to compare the word I type in to the set word in the object 'secretword'. I have tried everything from equal to == to compareTo, I even created a two hundred line program to do this SIMPLE problem.

obstacleX = (int) (obstacleX - 0.1);
if(obstacleX <= 0){
obstacleX = 600;
}
repaint();
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
}
}

So I've been getting back into Java and downloaded eclipse back onto my laptop. However when I go to make a simple rectangle into a JFrame, the frame will pop up but no rectangle will be shown. Here is my main class, which sets up the JFrame...
mport javax.swing.JFrame;
public class Frame{
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setTitle("I hope this fucking works");
frame.setSize(400,400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?
Making a JFrame is easy.
Adding a JPanel is a snap.

import javax.swing.JFrame;
import javax.swing.JPanel;
public class TheJFrame {
public static void main(String[] args) {

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 want that the cursor change when the mouse is over one of the rectangles. Rectangles are displayed but nothing happens when the mouse is over.
class Resizing extends JPanel {
java.awt.List myGuiList = new java.awt.List();
java.util.List<Rectangle> paths = new ArrayList<Rectangle>();
public Resizing() {
paths.add(new Rectangle(100, 100, 75, 50));
paths.add(new Rectangle(200, 100, 75, 50));

I need to do a rectangle using boolean array where true elements are the borders of the rectangle, and false elements are the inner space. I imagine that the first and last rows and columns must give the true element,
public class Functionality {
public static boolean[][] rectangleArray(int n, int m){
boolean[ ][ ] matrix = new boolean[n][m];
for(int i = 0; i <matrix.length; i++){
for(int j = 0; j < matrix[i].length; j++){

So here's my code as it is right now:
Java Code:
public class PrintHoledRectangle
{
public static void main(String[] args)
{
int width = Integer.parseInt(args[0]) / 2 * 2 + 1;
int height = Integer.parseInt(args[1]) / 2 * 2 + 1;
int centre = width * height / 2 + 1;
int index = 0;
[Code] ....
The width of the rectangle to be printed is given by the first argument, the height by the second
The centre tile ("[_]") of the rectangle (to be printed as " ") is given by the formula: ((width*height)/2)+1, assuming you count each tile left-to-right, top-to-bottom
My thinking is that the programme keeps a running count (seen as 'index') so that, when the centre tile is to be printed, it outputs " ", otherwise "[_]", hence the if-else statement
Currently, it prints "[_]" to infinity

I am just trying to move a rectangle in a diagonal line. When the applet pops up, the rectangle is there but doesn't move. If I drag the sides of the applet to make it bigger or smaller the rectangle will redraw itself and move, but I want it to move without touching the window.
Java Code:
package javaapplication3;
import java.applet.Applet;
import java.awt.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.Random;

Why does it only repaint when I resize the window?

I have created a method Rectangle and added a loop in my class Resizer (MouseAdapter) but impossible to resize the rectangles of the arraylist independantly !
class Rectangle extends Rectangle2D.Float{
private String name;
public Rectangle(float x, float y, float width, float height, String name) {
setRect(x, y, width, height);
this.name = name;

I was told to design a class named Rectangle to represent a rectangle.The class contains:
■ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height.
■ A no-arg constructor that creates a default rectangle.
■ A constructor that creates a rectangle with the specified width and height.
■ A method named getArea() that returns the area of this rectangle.
■ A method named getPerimeter() that returns the perimeter.
Draw the UML diagram for the class and then implement the class. Write a test program that creates two Rectangle objects one with width 4 and height 40 and the other with width 3.5 and height 35.9. Display the width, height, area,and perimeter of each rectangle in this order.Here is my code for the Rectangle Class:
class Rectangle
{
double width;
double height;
public Rectangle() {
width = 1;
height = 1;
[code]....
The error that I am given when I compile the driver is as follows:constructor Rectangle in class Rectangle cannot be applied to given types; required: no arguments; found:int,int; reason: actual and formal argument lists differ in length.

I have run into a bit of a head scratcher, at least to me. I am building multiple rectangles using double precision. I had to switch from int to double due to another issue that requires decimal places. Now, my fillRect (last line in the code section I posted) is causing an error as it only wants to work with int.
public void draw(Graphics2D g2) {
// check that sizes are above 0
if ((rectWidth <= 0) || (rectHeight <= 0))

I'm trying to build a program which sets a fill color for a rectangle. Each time the mouse is clicked the fill color changes according to the position of the mouse's X and Y. I succeeded to create a JFrame with a changing background according to the Mouse's position, but I can't seem to change the color of the rectangle (defined in MyPanel class).
This is the current code,
import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.SwingUtilities;
import javax.swing.JFrame;

I want to write a method which would give us a rectangle with numbers. The input is an integer which represents the length of a line in rectangle and the result type is void. The example for n=4 is:
3210
0321
1032
2103
