Tossing Coins For A Dollar Java Program?
Jan 29, 2014
The question is we have to write a class named Coin. The Coin class should have the following field:
A string named sideUp. The sideUp field will hold either "heads" or "tails" indicating the side of the coin that is facing up.
The Coin class should have the following methods:
A no-arg constructor that randomly determines the side of the coin that is facing up ("heads" or "tails") and initializes the sideUp field accordingly.
A void method named toss that simulates the tossing of the coin. When the toss method is called, it randomly determines the side of the coin that is facing up ("heads" or "tails") and sets the sideUp field accordingly.
A method named getSideUp that returns the value of the sideUp field.
Now we have to create a game program using the Coin class. The program should have three instances of the Coin class: one representing a quarter; one representing a dime, and one representing a nickel.
When the program begins, your starting balance is $0. During each round of the game, the program will toss the simulated coins. when a coin is tossed, the value of the coin is added to your balance if it lands heads-up. For example, if the quarter lands heads-up, 25 cents is added to your balance. Nothing is added to your balance for coins that land tails-up. The game is over when you balance reaches on dollar or more. If your balance is exactly one dollar, you win the game. You lose if your balance exceeds one dollar.
I think I've completed the Coin class but the game program is giving me problems. I got it to add the balances when they land on heads but it only does it one time. I'm trying to figure out how to input a loop but I haven't had any luck.

We are working with Java and Eclipse..One of the assignments asks to "Write an application that determines the number of coins in a jar and prints out the total in dollars and cents. Read integer values that represents the number of quarters, dimes, nickels and pennies. Use a currency formatter to print the output."

I'm very new to writing code (college freshman) and I need a code that prompts for and reads in the number of coins in one of the piles, as well as a String containing a single letter to indicate the type of coin in that pile: "P" for pennies, "N" for nickels, "D" for dimes, and "Q" for quarters. The program then computes the value of that pile of coins and prints it out. Here's what I have so far:
import java.util.Scanner;
/**
This program reads a student's final class average,
and prints out the appropriate letter grade..
*/
public class Coins
{
public static void main(String[] args)
{
// Define constants

So, I am supposed to write a program that calculates the total annual compensation for a salesman using user input for the salary, sales, and commission rate (list of 3 predefined commission rates. have to display in dollar format the amount of commission and total annual salary.
CommCalc class
public class CommCalc
{
//attributes of class, stored data
private double sales;
private double salary;
private double rate;
//and a total field? beware stale data.
//store sales argument from sales field
public void setSales(double sal)
[Code] ....
I know that i have to fix some of the semantics . I have this code that I made earlier, is there an easy way to make it into a GUI interface? Or will I have to go throughthe code lines to add the JOptionPane? And I am a little confused on how to make a list (array) for the commission rate.

I have a simple java program to write which tells the user combination of coins that equals to the amount of change i.e:
user input 87
output:
3 quarters
1 dime
0 nickels
2 pennies
How the program remembers the remainder which is passed to the next column of let say dime
i.e
originalAmount = amount;
quarters = amount /25;
amount = amount % 25; <---- this is confusing for me?!?! how can the integer = integer % 25
dimes = amount / 10; <--- HOW THE PROGRAM remembers the "remainder" instead of the original user input as the code it self tells you dimes = amount where "amount" is what user input NOT remainder.
amount = amount % 10;
so on ....;
What I don't understand is HOW this algorithm works. I mean we have int amount where user inputs the number we get the first calculation amount/25 = how many quarters and then amount %25 WILL tell us about the reminder. By looking at this piece of code I would say that the system should start the calculation for the dimes again from the original number since the code says dimes = amount/10 AND amount = amount%10. My understanding is that the calculation should be done from the original user input.
Book or code it self is not clear for me how the reminder is "REMEMBERED" and then pass on to the next calculation>!?!?
UNLESS the code: amount=amount%25 gets the remainder so the next code under it is REQUIRED to read from the last prompt code.

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

I want to develop a Java program that uses OpenScript APIs to test my applications. The OpenScript framework automatically creates the Java Code so I was thinking of either using this code or create my own using the APIs.
I tried both options using NetBeans but I'm getting errors everywhere starting with the library import. I'm pretty new to Java so I'm sure I'm missing a lot of things here. I pasted the code below from the OpenScript framework that want to use in a stand-alone file for your reference.,

I have spent quite a few hours trying to follow an API on how to use Actions in a java program.
I have 3 JButtons and have just added a JMenu. What I want to do is to add an ACTION so that the JMenu performs the same function as the JButtons. (i.e. they both do the same thing).
I have tried to copy and follow the example from the API forum.
How to Use Actions (The Java > Tutorials > Creating a GUI With JFC/Swing > Using Other Swing Features)
The first error I get in compiling is on the following line:
Action loadFile = new LOADFILE();
However, I get the following error message:
softeng2final2.java:49: cannot find symbol
symbol : class LOADFILE
location: class softeng2final2
Action loadFile = new LOADFILE();

I'm new to this so take it easy on my code!! It compiles but its not giving me the correct outputs and I can't figure out why. Two words or phrases in English are anagrams if their letters (and only their letters), rearranged, are the same. We assume that upper and lower case are indistinguishable, and punctuation and spaces don't count. Some examples and non-examples:
* The eyes / they see (yes)
* moo / mo (no)
* Clint Eastwood / Old west Action! (yes)
* Dormitory / Dirty Room (yes)
For more examples, see here.
Your job for this assignment is to solve a slight variant of the traditional anagram problem called superanagram. Here you are to write a two class application that reads in two words or phrases from the keyboard, and then judges if the first phrase is an anagram of some of the letters in the second phrase. Here are some examples:
* mo / moo (yes)
* mo / mOO (yes - capitalization doesn't matter)
* moo / mo (no - first phrase is NOT an anagram of some (or all) of letters of second)
* rip / ziPPer (yes)
* abc / aabc (yes)
* aabc / abcde (no - too few a's in the second string)
* flipper / rip (no)
* Clint Eastwood / Old west Action! (yes - the two can have exactly the same letters)
You must use the Scanner class to read in the input strings. Use the nextLine() Scanner method, rather than next(), since spaces may be present in the two phrases that are submitted.Your program should either print YES, if the superanagram relationship is satisfied, or NO, if it isn't.
The classes MUST be called SuperAnTester, and SuperAnagram
* use the String methods toLowerCase() and (possibly) toCharArray(). The former takes all letters in a String and changes them to lower case; the latter converts a String into an array of characters. Also, this assignment is - of course - about characters and character matching. For some useful background on characters and how to work with them, watch the movies in the textbook at the ends of section 4.1 and 7.1.
* Very important: suppose you have two arrays of characters such that the first is purported to be an embedded anagram of the second, in the sense we've described above. How can you tell? The single most important thing to do, before you write a single line of code, is to work out a paper and pencil algorithm that distinguishes between superanagrams and non-superanagrams.
* Your classes must be commented! In particular, each method must have a one line comment just below the header line, which tells what the method is supposed to do.
* Algorithm Idea #1: make a scoreboard for the letters a to z. Every time you encounter a letter in the second String, up its count by 1; Then, every time you encounter a letter in the first String, lower its count by 1. Accept if the scoreboard ends up with all entries >= 0. (of course make sure you understand why this is - use pencil and paper to convince yourself!!).
* Algorithm Idea #2: convert strings to arrays. March down first array (representing the first string). When you encounter a letter, look for it in the second array. If you find it, blank out the occurrence in the second array; if you don't find it - it's not a super anagram. When you're all done, you've got a superanagram if your search in the second array never goes bad.
public class SuperAnagram{
private String wordOne;
private String wordTwo;
private char firstArray[];
private char secondArray[];

I'm trying to make a java program that draws a spiral like this: [URL] ....
It was use a draw method to draw it in a specific way. What I have in my code so far is:
for (int i=0; i<line.length; i++) {
line[i] = new int[4];
line[0].x = 0; line[0].y = 0;
line[1].x = 0; line[1].y = boxSize;
line[2].x = boxSize;line[2].y = boxSize;
line[3].x = boxSize;line[3].y = 0;
It would be made through a 2d array and the values for how big the lines are would be stored in another file called line_details.txt which contains these values 0 200 1 175. So how would I implement this stuff into a Java code?

This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.
The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.

FootballClub should include statistics such as how many wins, draws and defeats an instance of it has achieved in the season, the number of goals received and scored. The number of points that a club currently has, and number of matches played.
Task 2. Implement a class PremierLeagueManager which extends interface LeagueManager. PremierLeagueManager class maintains a number of football clubs which play in the premier league. The class should create a menu based on text input and give the user the choice of:
• Create a new football club and add it in the premier league.
• Delete (relegate) an existing football club from the premier league.
• Display the various statistics for a selected club.
• Display the Premier League Table
Here is my code for Task 1:
public abstract class SportsClub {
int position;
String name;
