Count Results By Transforming Numbers Into Symbols?
Oct 23, 2014
i am trying to turn an int number etc. 6 into 6 symbols the result would be "------". how can i transform int=6 into "------"? what function do i have to use to do this count?
public class Diagram {
public static void skrivDiagram() {
Random rand = new Random();
int[] frequency = new int[13]; {
for (int roll = 1; roll <= 100; roll++)
[code]....
Here i want to transform the frequency[face] into "-".
I have been working on this for hours and cannot get it to work properly. The program is to count the number of characters contained in both strings and display the results. It is also to display the final statement, but only once. This version has a complete statement for each matching character.
import java.util.Scanner; public class CountMatches { public static void main(String[] args) { String firstStr = (""); String s1 = firstStr;
I've been working on a program where you can interact with the computer and play a guessing game of numbers between 1 and 100. It's mainly finished, I just need to add in my comments and stuff. My one problem about it that I cannot figure out is trying to get the results to give the correct int. At the end of the game, it's supposed to return the user information about how well they did like this:
Overall results: total games = int total guesses = int guesses/game = double best game = int
best game should give you the least amount of guesses you had during a particular round of the game. Here is what I have so far:
import java.util.*; public class Guess { public static final int MAX = 100; public static void main(String[] args) { intro(MAX); Scanner console = new Scanner(System.in); int tempBestGame = 0;
The purpose of this program is to import via keyboard Numbers.txt and calculate the mean and standard deviation to Results.txt.I am able to get the mean calculate but when I open the Results.txt the standard deviation is 0. I don't know what is wrong with my code, but I believe it has something to do with the scanner being close. Here is the error message i receive after inputting Numbers.txt.
java.lang.IllegalStateException: Scanner closed at java.util.Scanner.ensureOpen(Unknown Source) at java.util.Scanner.hasNext(Unknown Source) at StatsDemo.main(StatsDemo.java:48) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at edu.rice.cs.drjava.model.compiler.JavacCompiler.runCommand(JavacCompiler.java:272)
Java Code:
import java.text.DecimalFormat; //for number formatting import java.util.Scanner; //for keyboard input import java.io.*; //for using files public class StatsDemo { public static void main(String [] args) throws IOException
import java.util.Scanner; public class CountStringNumbers { // show the number of Strings that were numbers . . .. public static void main(String []args){ int count = 0; int countNumbers=0; Scanner input=new Scanner(System.in);
[code]...
can count the numbers from 0-9 if the user puted but if it is 10 it doesnt count it , and i need to write all the numbers to have that option. . . . Is there an easy way that includes all the numbers? like if(word.equals(number)){<<<???? (numbers) i know htat doesnt work but is there anything similar ?? ??
countNumbers++; } System.out.println("Type Something , , , and to end the the termination type STOP"); word=input.nextLine(); count++; } System.out.println("You wrote "+count+" lines wich from those lines "+countNumbers+" were numbers and the programe terminated "); } }
import java.util.Scanner; public class main { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int number; System.out.println("Input a number");
[code]....
What i want to do is that if the number is greater than 50 to count until 100. else if the number is less than fifty to count for example from 36 to zero.
I'm trying to make a program that will count each letter like if I put the word
e-1 h-1 l-2 o-1
The problem I'm running into is that if I put something like How now, brown cow? It should give me something like this
b - 1 c - 1 h - 1 n - 2 o - 4 r - 1 w - 4
but it doesn't instead the whole program crashes because of the punctuation marks and the spacing. Is there a way for me to fix that? All I know is that it has something to do with the alphabet[pos(letter)]++;
import java.util.Scanner;
public class CharCount { static Scanner keyboard = new Scanner(System.in); //this method should allow the user to enter a line of text (that should all be lower case) and then go to the printResults method public static void main(String[] args) { String text, character; int count; char letter; int[] alphabet; System.out.println("Enter a line of text:"); text = keyboard.nextLine().toLowerCase();// any text entered will be lower case alphabet=countLetters(text);
I'm trying to generate random 100 numbers, from 0 to 9, in an array using Math.random, but it only outputs 0s which is very confusing to me. Also, I need to be able to count how many different integers there are like 0s, 1s, 2s... 8s, 9s.
Here's my code, I only got as far as the array then got stumped on the counting part.
import java.util.Arrays; public class countDigits { public static void main(String[] args) { //Create random generator and values int numbers = (int)(Math.random() * 10); int arrayCount = 1;
I'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21 22 44 66 44 23 11 111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0; int range1 = 0, range2 = 0, range3 = 0, range4 = 0; int count1 = 0, count2 = 0, count3 = 0, count4 = 0; while (mark >=0 && mark <=100) {
[Code] .....
"The problem is with the while loop, the one above is something I was experimenting with "
I need to write a program that checks whether a Java source-code file has correct pairs of grouping symbols and the program must implement the Stack<E> class to solve this problem.
Here is the file: [a({b,c}x{d,e})%x] (1+(2-3)/4+[(a-({b+c}*5)/2)+e] (a{b(c]}a)
I tried something like this, but I'm not exactly sure what I am doing wrong:
import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; import java.util.Stack; public class Driver {
My professor is a man who enjoys making his students form large, but often simple symbols with smaller letters. That might not have clarified much, so let me demonstrate:
VVVVVVV VVVVV VVV V Or... X X X X X X X X X Or lastly... O O O O O O O O
My problem is, that I've always been bad at figuring out the logic behind these.
I can kinda' see it (somewhat) in my head though... I'd need a double for-loop which depend on the sizes, one that monitors the spaces and one that monitors the symbols, with some conditionals in there. How to make symbols like this, using letters, in Java.
I have an array with the following characters {'E', 'L','E','P','H','A','N','T','P','O'}
now, I need an array that will store the first array such that only the occurence occurs e.g {'E','L','P','H','A','N','T','O'} Notice that the characters 'E' and 'P' occur twice and as a result were not repeated the second time in the new array.
How would one go about this using the counting elements technique?
I tried this but not sure how to use the counting elements technique.
char [] arr = new char{'E', 'L','E','P','H','A','N','T','P','O'}; char[] bucket = new char[(arr[0] * arr.length)]; for (int i = 0; i < len; i++) bucket[arr[i]]++;
i am trying to run a command in terminal the code is below if i run the command in terminal it works fine however when i run it from netbeans with code below nothing gets printed. however if i run a different command such as (ip addr) it works fine?
public static void a() throws IOException{ ArrayList lister=new ArrayList(); Runtime rt = Runtime.getRuntime(); Process proc = rt.exec("ps -ef | grep firefox");// the command i am trying to run to get pid of application InputStream stderr = proc.getInputStream();
I need to print certain information from an arraylist depending on the arguments the method has. I'm trying to print the last 3 methods from the database class but nothing is printing and I don't know what the problem is.
package hw3; import java.util.*; public class Driver { public static void main(String[] args){ /* Comments required PersonFileReader pfr = new PersonFileReader("person.dat"); ArrayList<Person> testData = pfr.readData(); Database db = new Database(testData); */
[Code] .....
On the driver class I just print what the methods from the database class do.
I develop a little app in javaee6 and jsf2. I have a search page which has a search form with 2 fields and a search button when i click search button the results should be displayed in searchresults page.
Issue: searchresults page is is not displaying records though it fetched records from table I'm able to achieve this using search bean as session scope but i want to use the scope as Requestscope.
how to display results in a PLAIN_MESSAGE. My program is converting hex to decimal and displaying the results. Here's the code:
package pkgfinal; import javax.swing.JOptionPane; import java.util.Scanner; public class Final { public static int Convert(String userInput, int base){ int running_sum = 0;
I have the code here to populate a GUI. I have the math and then print out and return a single number. I have tried to use setText in the class CalculateButtonHandler.
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class RectangleProgram extends JFrame { private JLabel lengthL, widthL, areaL, perimeterL, averageL;
I wrote this small program to take an octal number from the user and convert it to decimal form.
import java.util.Scanner; public class Decimal { public static void main (String args []) //gets octal number from user, later prints conversion { int octal;
[Code] .....
Some conversions work. For example, 77 will be correctly converted to 63, and 77777777 will be converted to 16777215. However, some conversions do not work. An example of this is 775002 gets converted to 74898.
I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.
I don't see any nodes that I add. Not sure why getting this error.

I am having the hardest time trying to figure out how to display an array in a 1-window GUI.
I can display 1 book separately, by basically ignoring the array and creating a new object for each book, but I need all 5 books to display in one window, and that's where I'm lost. I'd really like to use the arrayI built to generate the books in the GUI. The information of each book appearing horizontally, and the different books appearing vertically.
// Bookstore.java // This program displays information on multiple books
