Create A Class Called Dice To Represent SINGLE Cube
Apr 15, 2014
I need to work on this "Dice" program. I've done it twice already. I've also been pouring over examples on here and elsewhere online, but none of them exactly match what I'm doing, as they all say "Pair of Dice".Mine says: "Create a class called Dice to represent a SINGLE cube". It should have a method called roll() that randomly selects a number from 1-6 for the value of the dice."
It has to use java.util.random, not math.java, and it has to have numberShowing:int, roll():int, and main() all in it.The last part reads "Create a test main method for the Dice class that creates a dice and rolls it many times. Can you keep track of how many times a number comes up? Describe how or implement it in the program." I have started at this computer for hours, and read as much info as I can.
Create a class called DiceStatistics to represent a pair of dice and the totals of their rolls. It should have an array of two Dice as a private data member (these are the Dice from Problem 1). It should also have, as a data member, an array of integers to represent the possible totals of rolling two dice.
The class should also have the following methods:
initStats() to initialize all the totals to zero. rollOnce() to roll each die once, and add one to the correct totals element printStatistics() to print the number of times each total has come up over the number of runs.
Here is my code:
public class DiceStatistics { private final int NUMBER_OF_DICE = 2; private Dice[] dice = new Dice[NUMBER_OF_DICE]; private int[] totals; private int numberOfRolls;
[Code] ....
And here is the error:
run: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: Dice.roll at DiceStatistics.rollOnce(DiceStatistics.java:27) at DiceStatistics.main(DiceStatistics.java:55) Java Result: 1 BUILD SUCCESSFUL (total time: 0 seconds)
I know it has something to do with the fact that I need to somehow import the information from my first program "Dice" into this in order to actually get the dice statistics, but how do I do that?
How to create object for "class B" and call the "function_B" from other different class D where class D has no connection with class A? Here is my program.
public class A(){ void print(){} } class B{ void function_B(){} } class C{ void function_C(){} }
Here, A, B, C are in the same package. But class D is in different package.
We are doing a visualisation tool for point cloud research project. We use 3d sphere to represent each single point and when we have large number of points to display (~40,000), the rotation becomes very lagging.
What we have tried:
set JVM flag -Djavafx.animation.fullspeed=true, this worked a bit, but not significant.set JVM flag -Djavafx.autoproxy.disable=true, this did not work.
set Cache to true and CacheHint to Cache.SPEED, this did not make much difference.create another thread to do the rotation, and sync back after calculation, this did not work neither.
i am trying to write a coin program:Write a class called Coin which will be used by a program called CountFlips.
1. The class, is an object created from this program. It is composed of data values and methods. It should contain a main method and should output the number of flips done (an integer that will be read from the user), the number of heads and tails that occur.
2. The CountFlip class will flip a coin multiple times and counts the number of ‘heads’ and ‘tails’ that result. This class should have a method called flip() of type void; a method called isHead() of type Boolean and a toString() method that will return the current face of the coin as a string.
So i created 2 classes, one called Coin.java & the other CountFlips.java,
PHP Code: package test; public class Coin { private final int heads = 0; private final int tails = 1; private int facetype; private int flips;
I have the following listener on a tableset of names:
ListSelectionListener singleListener=new ListSelectionListener() { public void valueChanged(ListSelectionEvent e) { int row=e.getFirstIndex(); if (row==previousRow) { row=-1;
[Code] .....
The println shows that getValueIsAdjusting is called 4 times when I click a single selection from the list. Is this normal behavior? If so how do I determine which call to really use. If not, where can I look to see why it is being called 4 times on a single click?
1)A factorial of a number X is equal to X*(X-1)*(X-2)*...*1.For example,3! is equal 3*2*1=6.Create a class called Factorial Algorithm which will compute and print the factorial of an integer number on the screen
2)Write a Java program to accept eight integers and a search element from the user and display whether the element is found or not.(Hint:use bubble sorting and binary search)
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.
2. Declare a class called Quadrilateral that can be used to represent a quadrilateral. What instance variables are required? This class should include the following methods:
• Accessor and mutator methods. Notice that negative and zero lengths should not be accepted. • A method called isParallelogram that returns a Boolean value indicating if the quadrilateral is a parallelogram. • A method called isRectangle that indicates if the quadrilateral is a rectangle. This method should invoke the method isParallelogram and return a Boolean value. • A method called isSquare that returns the Boolean value “true” if the quadrilateral is a square. This method should invoke the method isRectangle and return a Boolean value. URL...
import java.awt.Point; public class Quadrilateral{ private Point p1, p2, p3, p4; public Quadrilateral (Point p1, Point p2, Point p3, Point p4) {
We have to create a program called MyStack.In Push: Add one element at the end of the buffer.In Pull: Remove one element from the end of the buffer. In isEmpty: Should check if the list is empty or not and return the result as a boolean variable.
I am totally confused, I wrote the buffer and the array, but how do i add an remove element from the buffer?How do i add an element? What Statement do i Use?
Java Code: public class MyStack<T> implements Stack<T> { private final T[] ringbuffer; int index = 0; int last;
The game is too have two players, each user clicks a button and two dices will roll, if a user rolls a double they win.
firstly I have started with two imageview's and a button I am trying to randomise two images by clicking one button I have managed to randomise one image in one box but I am struggling to randomise both image views here is my code so far.
I'm finishing up this assignment, and I'm stuck. These are the last 2 instructions:
. Roll each of the Dice by invoking the roll method on each Dice in the array. . Keep track of the totals sum of all the dice in the array. Be sure to roll the dice array at least 10000 times.
How to finish it up?
Here's my code so far:
package homework3;
import java.util.Random; public class Dice { private int numberShowing; private final int numberOfSides; private static final Random randomNumber = new Random(); public Dice() { numberOfSides = 6;
Create a method called mirrorImage, which takes two integer arrays as input parameters. You may assume that the two actual parameters have the same length. Your method should return true if the arrays are the reverse of each other. Otherwise mirrorImage should return false.
Examples:
data1:{1,2,3} data2:{3,2,1} ==> true
[code].....
I'm pointing a place outside of the array or something
I am making a simple battleship program, you have the menu and click Start to get the board with the bombs (4 buttons as of now) Each button has either a bomb or a defualtbutton. I created my button so it can't be unselected. The problem is I have the button in a Class.java and I want that to close in a period of time. What do you recommend using?
/* * To change this license header, choose License Headers in Project Properties. * To change this template file, choose Tools | Templates * and open the template in the editor. */ package battleship; import java.awt.Dimension; import java.awt.EventQueue; import java.awt.GridBagLayout;
[code]....
I can call the clas in my main jFrame but I want to close the class after a certain time.
Write an instance method, contains, that has one explicit parameter of type Rectangle. The method should return true if every point of the rectangle determined by the explicit parameter is on or within the rectangle determined by the implicit parameter. It should return false otherwise.
My java class doesn't execute a shell sript, I had given the java io file permission read and execute over the script shell to the user who execute the java class, also I executed the script shell in the console each RAC server using oracle user session and the srcript shell works. My team DBA told me that " The user server process is oracle". My script shell resides in all RAC server file system the last result looks as follows:
/home/mydir/dir2/mybin/compacta_archivo.sh No Funcionando!! java.io.IOException: /home/gi91591/reppostpago/bin/compacta_archivo.sh not found
[Code]....
of course, the script file exist on my file system, it has the suitable permission as the test result i got each time I executed on the console. My Oracle version is 11.2.0.3.0 on Rac ASM.
I want to have two threads running in my class, one will be downloading info from a website then putting the thread to sleep for a little bit, then repeating. The other will be sending information to a website then putting the thread to sleep for a little bit, then repeating. Is it possible to do this in my main class? I already have one thread using run() for downloading the info and sleeping can i make another?
I've been into java for about 4 months now, No complaints so far, it's pretty awesome! So I understand Polymophism pretty good, I did some Animal classes and it worked out neatly.
However. I just can't seem to find my way in OOP when trying to implement in on a Calculator Class I wrote. As you mind know, a calculator can be separated into many classes. But I actually just want it to be separated into some OO like: | Calculator | CalcGUI | CalculatorFunctions | CalcRun.
I tried separating the single Calculator class, however, my calculator Buttons didn't work after that, anymore..
I am trying to create a second class in a single java file (first time trying this) and want to use data from the first class in the second class but I am not able to do it. What am I missing :
package simplecommissioncalculation; import java.util.Scanner; // import java.util.Scanner public class SimpleCommissionCalculation { public static void main(String[] args) {
I am currently working on a dice game. I have a private method called rollDice and it performs the action of rolling two dice. For my project, I need to create another method called playerRolls and I am supposed to invoke the rollDice method in the playerRolls method and perform actions based off of that. My question right now is how do I invoke a method into another method of the same class?
I have created an application using hibernate and struts.In which a form is created where the user will enter all its personal details(for e.g name ,phone no. and address).
Here for address I have used textarea and whenever user enters the address, sometimes it can be a long string also.
So the problem is if a long string is entered then while displaying that ,address comes on single line and the page is stretched.
how to break this single string into mutiple lines in java class?
In the class below I'm trying to create a class that will accept dates in various formats and create a range. The first constructor is easy because I send it the begin date and end date as Date objects. Now I want to send a month(and year) in a constructor and derive the begin and end dates from it. In my constructor that accepts the month/year I need to put the this(startDate, endDate) at the top to be allowed, but the parameters are not built yet.
package com.scg.athrowaway; import java.util.Calendar; import java.util.Date; public class DateRange { private Date startDate; private Date endDate;
I have found out the area that causes this, my toString, but I want to know if there is something built in or not that will allow me to print it such that I can continue printing it at the same row level as its neighbor, even though I create a new line for each individual column? Here is the code that I try to print out the entire cube:
