Flip Function - Making Coin Stop On Random Heads Or Tails
Nov 19, 2014
I cannot figure out why my buttons don't work. I believe my problem is in the flip function. I am very new to programming and I am about as good at code logic as I am at real logic lol. Also I am lost on how to go about making the coin stop on a random heads or tails.
Coin cF;
void setup() {
size (600, 600);
cF = new Coin(0,0,0);
}
void draw() {
background(100,100,100);
//Coin(int lX,int lY, int cSize)
//location(int l_x, int l_y)
//flip()
I am supposed to write a static method that simulates a flip of a weighted coin by returning either heads or tails each time it is called. The coin is twice as likely to turn up heads as tails. My idea was to of course use a random class
Random flip = new random
and somehow initialize it so 3 numbers are called and create if statements so that when 0 and 1 are called heads returns and when 3 is called tails is.How do I put all this together?
and then maybe some cheeky text about how the machine stole your money.
The actual coding for me however is very difficult as I really don't know how to convert the string input from the user into usable numerical and substrings for the calculations.
I have some basic skeleton code worked out, but its only designed to run once.
import java.util.Scanner; public class CoinStar { Scanner input = new Scanner(System.in); public static void main(String[] args) { /** this first section is supposed to take the string from the user and separate it into two substrings, * one integer, one word string *
So I have a program for a project that permutes a random series of numbers using Java's Rand function. Basically I use a seed and a number of items I want in the arrangement of numbers, and the program makes a permutation with no two numbers being repeated. Only arrays can be applied to it, so I've been hard at work finding a solution.
Here's the code so far:
public static int permutation[]; public static void permute(int numOfItems, int seed){ permutation=new int[numItems]; Random rand = new Random(seed); permutation[0]=rand.nextInt(numItems-1);
[Code] ......
So basically I'm wanting the program to make a randomized list of numbers from the number of items I pass to the Permute method with no duplicates. I'm having some level of success with what I have written, as it gives me a randomized list when printing the output, but for some reason the first for statement in code never terminates fully, but instead runs indefinitely when generating the last integer.
For example, if I want to put 10 with a seed of 0 into it and make a list from 0-9, it will print 74283510, which is only 8 different integers. permutation[0] is manually set at the beginning of the method, which accounts for one more, but that's still only a list of 9, so I'm just wondering why the last integer is not being generated and why the program keeps looping and not terminating? I'm know for sure it's something I'm overlooking.
I have to random shuffle an array of Card Objects which does the funcion of a deck. Heres the code:
Java Code:
public void barajear(){ int j; for (int i=0;i<52;i++){ j=Baraja.random(51); if (this.mazo[j]==null){ this.mazo[j]=this.arreglo[i]; }else{ --i; } } } mh_sh_highlight_all('java');
so bassically theres an array called "arreglo" which has the cards in order and the function "random" its an rng of numbers from 0 to 51.what i'm trying to do it's to take the cards from the ordenated array and put them randomly in the other but only if it's empty.(the array "mazo" has alredy been initialized with null).it worked at first, but now, after compiling succesfully i tried to run it and the cmd just...
How do I record the number of times all runs of heads occur. Ex.
Length Number of runs of heads 1 --------------------3 2 --------------------2 3 --------------------0 4 --------------------1
public static void main(String[] args) { int [] coinToss = new int[TOSSES]; int longestRun = 0; int run = 0; for(int i = 0; i < coinToss.length; i++) coinToss[i] = toss();
What's a simple way to flip an Image along the vertical or horizontal? I've searched high and low and surprised to find that I can't find something short and compact.
I do not understand how I can alter my paintComponent. Is it possible to set my paintComponent to an Image variable, and then flip the image with Math.Radius?
I am trying to create a program that asks you the number of times you want a coin to be tossed, and then outputs the number of times it "landed" on heads in that inputted number of times. I want it to output something like "number of heads:". Instead my program outputs multiple lines saying "number of heads: *a number*" or "number of tails: *a number*".create the output I want by modifying my program?
Java Code:
import java.util.Scanner; public class Lab04 { public static void main(String [] args) { Scanner in; in = new Scanner(System.in);
I am having trouble creating a driver for the following program. im new to creating interfaces and i need to make this work.
Lockable interface:
Java Code:
public interface Lockable { boolean locked(); public void setKey(int key); public void lock(int key); public void unlock(int key); } mh_sh_highlight_all('java');
what im trying to do is modify the Coin class to override the toString() method so that it indicates whether the coin is face up or face down. For example, "The coin is face up." This is what i have so far:
public class Coin { public static void main(String[] args) { Coin coin = new Coin(); for (int i = 0; i < 1; i++) { coin.flip(); System.out.println(coin);
I'm having some issues getting this code to reject negative numbers. What I'm doing wrong.
import java.util.Random; import java.util.Scanner; public class ForLoop { public static void main (String [] args) { Random randomNumber = new Random();
I am trying to flip a coin 1000 times and make the driver class count the number of times a head and tails appear. However, I am having some trouble trying to figure out the error:
package Week5; import java.util.Random; public class Coin { private int heads; private int tails; private int face;
[Code] ....
I was able to print out the generated numbers, but java will print either heads or tails a thousand times and count that as 1000 and nil for the other probability...
So my goal is to use the graphics class to draw this shape: [URL] ....
so far I've managed to draw the bottom half, but now I want to utilize the copyArea() method to flip the bottom half and copy it to produce the upper half of the shape: [URL] ....
and this is what I wrote to produce the bottom half:
import java.awt.Graphics; /* * 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. */
public class MyFrame extends javax.swing.JFrame {
/** * Creates new form MyFrame */ public MyFrame() { initComponents();
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road. If you choose to cross, the outcomes for 0-2 are "You crossed safely." For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street." For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working. I have up to here:
import java.util.Random; public class test4 { public static void main(String[] args) { Random random = new Random(); for(int i =0; i < 1; i++){ int num = random.nextInt(10) + 1; System.out.println("The number of cars on the street are: " + num + "Do you wish to cross the road?"); } } }
In the code that I am currently trying to do, I want to make it so that the program loops until the randomly generated number is 1, to a maximum of 4 loops.I have figured out how to make it stop at a randomly generated 1, but I can't quite figure out how to make it stop at four loops if it doesn't reach the 1 before the maximum number of loops.
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;
how many integers the user wants to use. The user will enter for example a 4. The user inputs a 2, 4, 6, and 10. So then we get our outputs...Then the code will ask if you want to run this program again. My question is, if the user inputs a -1 for example 2, 4, 6, -1....the code will not continue. I wanted to use a while loop, such as while (scores != -1) but it doesn't work.
Enter the amount of integers you want to use4 Intenger # 1 2 Intenger # 2 4 Intenger # 3 6 Intenger # 4 10 You entered 2.0 4.0 6.0 10.0 Average = 5.5 Variance = 8.75 Standard Deviation = 2.96 Do you have another set of numbers?
I made a check4 application with Java.It correctly works but sometimes the application just stop itself during the execution.I never had a problem like this. The application just stop itself and i can't even quit using the closing button..
I am developing application called java compiler... It takes java program as input and compiles and run it, gives output. but if input program has infinite loop then how can identify and stop process execution.
I am making a project that should play, stop, and loop three different songs (not at the same time). I am calling this SoundPlayer class from my main class:
import javax.sound.sampled.*; import java.util.*; public class SoundPlayer { List<AudioInputStream> songs = new ArrayList<AudioInputStream>(); int currentSong, currentPlayType;
[Code] ....
When my class calls setPlayType(2), which should make it play, I get the following runtime error:
java.lang.NullPointerException at SoundPlayer.playSong(SoundPlayer.java:32) at SoundPlayer.setPlayType(SoundPlayer.java:64) at MainPanel$AListener.actionPerformed(MainPanel.java:60) (...)
Line 32 is if(clip.isOpen()), but I'm pretty sure I instantiated clip properly in the constructor.
What I mean is, I have this set and it is supposed to take out all the duplicates. If I enter aaabbbcccd the output should be abcd, but instead my code just outputs the last word, or in this case letter entered.
import java.util.*; public class setdemo { public static void main(String[] args)
I am making a WebCrawler, and I am trying to work out a way to stop duplicate links from getting put in however ArrayList.contains() doesnt seem to be working for me can someone look at my code and see if I am doing something wrong? I have also tried variations of it such as
!link.contains(newLink) and !link.contains(newLink.getLinkUrl())
I am trying to program a slot machine and as of now, I am trying to make my slots spin and randomly stop on one of the graphics. Right now, I am having difficultly making the animation/slot stop randomly.
Previously, I tried using a randomly set timer that would cancel the execution, but the image did not appear/stop on the screen.Right now, I am using a random generator and a while to say that if it is a certain number, then stop the image.Here's what I tried:
I have a Stream instace which produces values using an infinite Supplier (it supplies values taken from an electronic sensor -- so unless the battery is low, the sensor will provide "for ever").
The stream is processed by a Collector using Stream.collect() (e. g. imagine that the values from the sensor should be averaged; in fact what it does is a bit more compliacted maths).
The problem is that the collector does not produce a result but hangs up, as the supplier does never stop providing more sensor values.
So what I need is a limitation rule that stops the stream. While there is a Stream.limit(long) method, it actually does not solve my problem as in my case it is not practical to stop after a particular count, while I actually want to stop streaming when the sensor value exceeds a particular limit etc. (hence, voids an arbitrary rule).
To sum up, what I need is Stream.limit(Predicate), i. e. the stream will stopped once the predicate becomes true.
Unfortunately I did not find anything like that in JRE 8.
Is that planned for JRE 8.1 or JRE 9.0? Or is there a known (and sophisticated) workaround?
