Print Array Asterisk Bar Chart

Jul 6, 2014

I am trying to get this program to take 5 integers from a user and print a bar chart made of asterisks. The only way I've been able to access the values stored in the array is when my loops are nested, but this keeps my output from printing the way I would like it to.

It prints:
Enter a number:
2
**
Enter a number...and so on

I want it to take the values say(2,3,5,8,4) and do this:
**
***
*****
********
****

public static void main(String[] args) {
// TODO Auto-generated method stub
Scanner in = new Scanner(System.in);
int[] barArray = new int[5];
for(int i =0; i < barArray.length; i++){
System.out.println("Enter a number: ");
barArray[i] = in.nextInt();
for(int j = 0; j < barArray[i]; j++){
System.out.print("* ");
}System.out.println("");
in.close();
}
}

first question: is the code clean and the method correct?

2nd question: i get an error when i try to print the newInt Array for no apparent reason.

Java Code:

public class viereinsdiezweite {

I am new to programing and I am making a dice game where I have to roll two dice and add the total together for each dice (2, 3, 4 ect.) I have all the program finished except one thing.

How would I use the * character that shows the total percentage each number was rolled. Each * will represent 1% of the total rolls. Instead of saying there were ( 4 ) 2's rolled i have to put ( **** ) 2's rolled.

Convert Array Of Integers To Array Of Characters And Then Print It Out

Feb 13, 2014

I have double checked this code over and over and I just can't find the problem.

What I'm trying to do is take a file and input it into an 2D array.

Ultimately, I should convert the array of integers to an array of characters, then print it out. The file contains a set of ASCII values.

After printing it out, I should then create methods to manipulate the image produced.

Using 2D arrays is a requirement for this exercise.

I think that somehow I'm overcomplicating this and the solution is a lot more simple than I think, but I can't think of what to change.

The error I am getting is:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 40
at main.main(main.java:17)

Java Code:

import java.util.*;
import java.io.*;
public class main {
public static void main(String[] args)
throws FileNotFoundException {
String[][] data = new String[22][40];

Sort Array List Print?

Nov 23, 2014

I am having an issue trying to print different types of arrays using one method. Eclipse tells me to convert my print method for each array type:

change method 'printList <e>' to 'printList(ArrayList<Double>)'
change method 'printList <e>' to 'printList(ArrayList<Character>)'
change method 'printList <e>' to 'printList(ArrayList<String>)'

I would like to accomplish printing all four different arrays using one print method. How to accomplish it or provide examples or links to examples?

How To Pass Array From Servlet To JSP And Print

Dec 12, 2014

I'm trying to pass an integer array,

int[] fibSequence;

From my Fibonacci servlet to a jsp page called "result" but when I pass the array in the redirect I get the following output:

[[I@63cf2179]

I figured out that this is because the array is being converted to string before it is passed over and then converted again on the jsp page.

How I can pass the array over and print the contents, ie an array of integers?

This is how I'm sending the array in the result page:

resp.sendRedirect(("result.jsp?fibSequence=" + fibSequence));

And this is how its being retrieved and printed on the result.jsp page:

<%String[] fibSequence = request.getParameterValues("fibSequence");%>
<input type="text" name="fibNum" value="<%=java.util.Arrays.deepToString(fibSequence)%>" size="40px" style="font-size:30pt;height:60px">

Print Array Output On Different Lines

Nov 19, 2014

I've to read in an array of 1000 random numbers, and then my program sorts them depending on whether the user chooses bubblesort, selectionsort, etc...My code all works fine, my problem is with the actually output display. I have method that displays the content of the array that I call for the unsorted array, and for the sorted array. So at the moment the output to the user looks like:This program sorts an array of numbers by your choosing.

Array before sorting:
148
626
817
4
312
652
643
134
etc... for 1000 numbers

----------------------
1. Bubble Sort
2. Selection Sort
3. Insertion Sort
4. Merge Sort
5. Quick Sort
----------------------

Please enter your sort choice: 4

Array after sorting:
1
3
4
4
5
6
6
7
etc... for 1000 numbers

is there a way that I can display the unsorted and sorted array's content on various lines like so:

150 312 149 31 392 384 66
498 909 35 602 568 897 131
654 645 274 264 895 281 462
244 171 958 649 740 351 344

I just think it'll look nicer if I can do it like that.My display method looks like this:

//method to display array
public static int[] displayArray(int[] array){
//display array
for (int i =0; i < array.length; i++)

Program Should Print Array As Output

Jul 11, 2014

Write a program to create an integer array of size 20. Then, the program should generate and insert random integers between 1 and 5, inclusive into the array. Next, the program should print the array as output.

A tremor is defined as a point of movement to and fro. To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.

Then, the final array should be printed as output. There is no user input for this program.Your program must include, at least, the following methods:

-insertNumbers, which will take as input one integer array and store the random numbers in it.
-createTremor, which will generate the random number as the location and return it.

A sample run of the program is shown below:

Sample output #1:
Array:1 2 2 3 1 5 4 2 3 4 4 2 1 1 3 2 1 4 3 2 1
Random position: 5
Final Array:1 2 0 0 0 5 0 0 0 4 4 2 1 1 3 2 1 4 3 2 1

Multiply Every Number In Array By 2 And Print It Out

Nov 2, 2014

My assignment is to write some code that will multiply every number in an array by 2 and print it out. This is using a site zyante which is a interactive online book kind of thing.

I have tried For (i=0; I < 8; i++) with like userVals = userVals * 2) }

And it doesn't like that so i'm guessing i am no where close to right. The chapter doesn't give me any example of doing anything close to this so i am completely lost on what i have to do.

This is the program :

import java.util.Scanner;
 public class NegativeToZero {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ELEMENTS = 8; // Number of elements

Enter In Sales Amount And Then Get It To Display Asterisk Per 100 In Sales

How would I get my program to display a * for every 100 dollars in sales that the user enters in so: for example the user enters in store 1: $ 400 in sales for the store I want it to display store 1:****

The first part of my code allows the user to enter in whatever values the stores have in sales. The Second half of the code starts at line 19 is my best guess on what I need to do I just am not sure how to get it to display what I need it to.

Unable To Print Out Randomly Generated Array

Nov 19, 2014

i am trying to print out a randomly generated array, but i only get

[I@7852e922

i did some research and the "[" is for arrays, "I" is for the int and "@" is the hash. and the rest is some sort of hex. I need to override this in a way, but i can't seem to find out how.
this is my current code:

import java.util.Random;

public static void main(String[] args){
int myint[] = fyll();
System.out.println(myint);

Unable To Print Repeating Integers In Array

Aug 5, 2012

I have a problem where i have to write some code to read through an int array and print out the different integers and how many times they occur. For example:

if the array contained the numbers 1,4,2,3,5,4,4,7,5,4,3,6,8,6,4,

i would need the print to appear something like this

integer: 1, times: 1
integer: 4, times: 5
integer: 2, times: 1

etc

as the array is read sequentialy from element 0 to the end. the program should find the integer value in the first element (increment a counter by 1) and then search all other elements to see if the integer reoccurs (counter++ for each time it reappears). obviously the counter would be the 'times' value in the second column.

My problem is i can get this accomplished yet i cant get the program to recognise when it has already registered an integer in a previous element and skip to the next element looking for a new integer. SO for each element in the array it prints the integer and then searches the entire array for the integer again and increments the counter accordingly. so in essence there is a line printed for each integer the number of times it actually occurs.

I simply wish to have my code to find an integer and the number of times it occurs. and then disregard the elements it has registered the previous integer in.

Also, keep in mind that i am NOT permitted to use any new data structures/arrays for storing/remembering values. I can only use int and double variables throughout.

what i have so far is this: with the array being customerID[] :

Java Code:

int num;
int counter;
for(int count = 0; count < customerID.length; count++)
{
counter = 0;
num = customerID[count];
for(int count2 = 0; count2 < customerID.length; count2++)

[Code]...

The output for the int array 1,1,3,0,3,2,0,4,1,3, looks something like this:

Integer: 1, Times: 3
Integer: 1, Times: 3
Integer: 3, Times: 3
Integer: 0, Times: 2
Integer: 3, Times: 3
Integer: 2, Times: 1

[Code]...

and as you can see lines are repeated for each time the same integer occurs in a new element. i just need my code to skip an element if the integer has been previously encounterd and recorded. i.e i need it to look more like this :

Integer: 1, Times: 3
Integer: 3, Times: 3
Integer: 0, Times: 2
Integer: 2, Times: 1
Integer: 4, Times: 1

with the first encountered integer being checked throughout the array and then moving to the next integer/element which is not the same as any previous.
