Finishing / Creating Checkerboard Program

Sep 9, 2014

I have my CheckerboardViewer done, my component is what I need finishing. My final product needs to be a checkerboard with alternating red and grey squares but the background is already grey. My code for the Viewer is:

import javax.swing.JFrame;
public class CheckerBoardViewer
{
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setSize(300, 400);
frame.setTitle("CheckerBoardViewer");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
CheckerBoardComponent component = new CheckerBoardComponent();
frame.add(component);
frame.setVisible(true);
}
}

And this is what I have of the Component:

import javax.swing.JComponent;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Rectangle;

[code]....

I've created one square so far, but I'm having trouble creating the code for at least the second square.

CheckerBoard Won't Appear - Creating A Game In Java

Mar 8, 2015

Anyway I am creating a game for my A2 coursework, most commonly known as Checkers. I have completed my code and everything works as I had planned except that the CheckerBoard itself as well as the checkerpieces do not appear to be showing.

The section of were my board should be present is just a black space. Although my board does not appear to be displaying, all of the actions I perform on it such as clicking certain section produces the planned response, and although I've checked through my code I cannot work out what I've done wrong.

CheckerBoard content = new CheckerBoard(); // Sets the CheckerBoard values into the content to be used in the next line
application.setContentPane(content); // Container holds the values together, Content pane of the CheckerBoard
application.pack(); // Use preferred size of content to set size of application.
Dimension screensize = Toolkit.getDefaultToolkit().getScreenSize();
application.setLocation( (screensize.width - application.getWidth())/2,
(screensize.height - application.getHeight())/2 );

[Code] ....

I have noticed is that within the BoardComplete(), if you change the setBackground(Color.BLACK) to WHITE, it will change the colour of the section to white, but the checkboard is still unshown.

Why Thread Loop Is Not Finishing Without Mentioning Printing

Jan 13, 2015

I was trying to read an article from here : [URL] ..... I was doing the same example but loop is not ending. Thread is struck at CalculateThreadDemo run method. If i mentioned System.out.println then it got terminated else infinite loop continues. I don't understand this.

code:

BlockedThreadDemo
public class BlockedThreadDemo extends Thread {
private boolean isFinished = false;
BlockedThreadDemo(String name) {
super(name);

[Code] ....

Without commenting the statement:

597222
597223
597224
597225
isFinished: true
main thread is dead
597226
CalculateThread is finished.

i: = 49i: = 13i: = 10
BlockedThreadDemo is finished.

Making Custom Checkerboard With Nested Loop

Feb 7, 2014

I'm trying to make a custom checkboard with given user input, in the form of (# of rows, # of columns, size of each square, filler character).

So the input 2 3 5 * would look like

*****.........*****
*****.........*****
*****.........*****
*****.........*****
*****.........*****
.........*****
.........*****
.........*****
.........*****
.........*****

I've made my loop, but I am unable to get more then a 1 1 1 checkerboard properly. I am stuck on how to divide the filler characters to make the proper square size. As of now they are all one lined.

import java.util.*;
 public class Checker{
 public static void main(String[] args) {
int col, row, size; char filler;
System.out.println("Please enter 3 numbers and a character."); //output

I don't get any error messages (which is good I suppose) but how to make the image show up because I have stuff under the graphics and draw methods, did I do something wrong where initializing the array?

Creating Encryption / Decryption Program?

Feb 25, 2015

For this week's assignment, I am supposed to create a java program that encrypt's a user's sentence, outputs the encrypted message, then decrypts the message, outputting the user's original message.

This is what I have so far. It doesn't compile the last few lines since that is not correct Java syntax.

Java Code:

import java.util.Scanner;
import java.io.*;
public class Decrypter {
public static void main(String[] args) {
String sentence;
final char REAL_ALPHA[] = { 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h',

[Code] .....

So you can see I have "realAlpha" which are regular letters of the alphabet, and "codeAlpha" which are the letters I want to encrypt with. I want 'a' equal to 'z,' 'b' equal to 'y', 'c' equal to 'x' and so forth in that sort of reverse order, you know? So the word "apple" would encrypt into "zkkov."

I am stuck as to how to replace the letters in this way. You can see I tried fumbling with sentence.replace to switch the letters out between the two arrays. Also, I only barely understand arrays.

Creating A Program To Call Classes

Aug 15, 2014

The requirements are as follows:Design and implement the class Day that implements the day of the week in a program. The class Day should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type Day:

A. Set the day.

B. Print the day.

C. Return the day.

D. Return the next day.

E. Return the previous day.

F. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add four days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday.

G. Add the appropriate constructors.

H. Write the definitions of the methods to implement the operations for the class Day, as defined in A through G.

I. Write a program to test various operations on the class Day.Should I break down my day.java into several separate classes, one for each of the sections (previous, next, etc)?

import java.util.*;
public class MyDay
{
static Scanner readinput = new Scanner(System.in);
String day;
public MyDay(String day)
{
day = "Sunday";

[code]....

Ideally I would like to create a Gui that would have someone type in the day, and then press a button to return the next day, prior day, or have a text input to test for adding X number of days.

Creating Number To Word Program?

Apr 1, 2015

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?

Creating Program That Will Handle A Golfer And His Scores

Apr 22, 2015

I have a project that is asking me to create a program that will handle a Golfer and his scores. The program will be comprised of three classes: a Golfer class that will manage all the golfer's scores, a Score class and a Tester class to drive the other classes. To accomplish this task the program will use a partially filled array to store the golfer's scores. I have the majority of the code written. It compiles fine, but when I compile and run it only gives the following output.

Tiger ID Number: 1001 Home Course: Pebble Beach
Score Date Course Course Rating Course Slope
[LScore;@15db9742

I am not sure what I am doing wrong. I have been over and over the code. It is also only printing one golfers information. I have tried creating a for loop for the for the toString in the Golfer class but I am getting the following error Golfer.java:117: error: missing return statement.

I am at a loss here is the code I have for the three sections.

public class Golfer
{
private String name;
private String homeCourse;
private int idNum;
private Score[] scores;
private static int nextIDNum = 1000;

Creating Palindrome Program - Arrays And For Statements?

Feb 14, 2015

I am trying to create a program that reads a sentence, such as: "abba is running to the radar" scans this sentence, and then prints out all the palindromes. I am running into issues with my arrays and for statements. Here is my code:

static String palindrome, backwardsLower,
palindromeLower, palindromeClean, backwards2, backwards = "";
static String[] words;
static int counter;
public static void main(String[] args) {
palindrome = JOptionPane.showInputDialog("Please enter a phrase. " +

[Code] ...

I am aware that there is a few "useless" variables in there at the moment, I will clean them up (as well as some useless statements, I see those too). The issue comes at about line 17. The variable backwards REMOVES all the spaces from the array, so when it comes time to compare the strings, it is comparing individual words to the ENTIRE string, thus no words will ever be a palindrome.

Creating A Program That Calculates Simple And Compound Interest

Aug 12, 2014

I need getting started designing and creating a program that calculates simple and compound interest. Simple interest in this case means that interest is only applied to the original amount. For instance, if a person deposits $1000 at 10% annual interest, then after one year they would have $1100 (the original $1000 plus the $100 interest) and after two years they would have $1200 (the original $1000, plus the $100 earned the first year, plus the $100 earned the second year).

With compound interest, the interest is applied to all money earned. So, starting with $1000 at 10% annual interest, after one year the user would have $1100 (the original amount plus $100 interest) and after two years the user would have $1210 (the $1100 they started with at the beginning of the year plus the $110 interest).

The requirements of this program are:

-Create a class that will hold methods to calculate the interest. Do not include the main method in this class.
-In the class that is used to calculate the interest, include a method to print to the screen, by interest period, the starting amount for the period, the interest earned for the period, and the total amount at the end of the period. Note that each period represents the time frame for how often it is updated. If annual is selected the period is every year. If it is semi-annual it is every six months. If it is quarterly it is every three months.
-Create a demo class that will use your interest calculation class. Prompt the user for the original amount, the type of interest (simple or compound), the annual interest rate, and whether it is updated annually, semi-annually, or quarterly. Use method calls to your calculate interest class to do all calculations and display the result. Loop the program until the user chooses to quit.

Sample output ($10000 initial investment, 10% simple interest, annual, for 4 years):

Period Beginning Amount Interest Earned Ending Amount
1 10000.00 1000.00 11000.00
2 11000.00 1000.00 12000.00
3 12000.00 1000.00 13000.00
4 13000.00 1000.00 14000.00

Creating TXT File - Program Keeps Printing Exception Error

// This program asks the user for input for a name, phone number and notes up to 200 entries.
// It stores every contact in a file. Type 'h' for help while running this program.

After running the code, I go into my workspace folder and I see that the file was created. What to do because running the program will always print "could not find the file".

Creating Program That Will Estimate Child Height Based On Height Of Parents

Jun 19, 2014

I am trying to create a program that will estimate a child height based on the height of the parents. It should ask the user to enter a String representing the gender, so m or M for a male and f or F for a female. The program must handle both upper or lower case gender entries. I need it to ask the user for the height of both parents in two parts:

1. for Feet and store in an int variable.
2. for inches and store and int variable.

So for example if the father is 6' 2'', the user would enter 6 when asked for feet and 2 when asked for inches. Convert the height of the each parent to inches. hint 12" in one foot.

Apply the following formulas based on gender (must use an if statement(s)):

Hmale_child = ((Hmother * 13/12) + Hfather)/2
Hfemale_child = ((Hfather * 13/12) + Hmother)/2

I cannot figure out what is missing from my code

<import java.util.Scanner;
public class ChildHeight
{
public static void main(String[] args) {
Scanner scannerObject = new Scanner(System.in);
String gender;
String male;
String female;
