I am trying to print out all of the values of an array and the average. I am getting part of the printout but I am also getting an array out of bound error message. what I am doing wrong?
int [][] points = new int [2] [3];
points [0][0]= 3;
points [0][1]= 2;
points [0][2]= 4;
points [1][0]= 2;
points [1][1]= 2;
points [1][2]= 2;
int totalPoints = 0;
int totalShots = 0;
I have been working on this program for a while and now i seem to be stump it throws an outof Bound array exception error, this program is a matrix multiplication program and spits out the resulting matrix using multithreading. i have a running one and result is
2 -1 0 1 0 3 -1 1 3
but this program's result is:
2 0 0 1 0 0 -1 0 0
it reads a txt document as an commandline arguement the text file reads just like this below:
3 2 2 3 1 0 0 1 -1 1 2 -1 0 1 0 3
the following is my code:
import java.util.*; import java.io.*; public class P3 { public static int matrix1[][]; public static int matrix2[][];
I have two codes of needed to run but after processing, the said above error is preventing it from getting the general output of the code.I can't seem to find my errors or I don't have any clue at all, if perhaps you know, here's the codes:
Error : PHP Code:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0 at simpleOutput.main(simpleOutput.java:13) public class simpleOutput { public static void main(String args[]){ int n = Integer.parseInt(args[0]); for(int i = 1; i <= n; i++){ } for(int i = 1; n <= i; n++){ System.out.print((i*n)+" ");
I am trying to avoid an out of bounds error for my heap array by checking to see if the current values left and right child are greater than the size of the array and then ending the execution of the code. However, I am still getting an out of bounds error even with that condition.
public void trickleDown(){ System.out.println("TRICKLE DOWN"); boolean repeating = true; int temp, leftChild, rightChild, leftIndex, rightIndex, parent = 0; while(repeating){
I am writing a java program that takes a FROM image, a TO image, and a ratio (this is a slide bar in the GUI). Here's my code: Java Code:
public static BufferedImage rollUp (BufferedImage from, BufferedImage to, double ratio) { BufferedImage finalBufferedImage = new BufferedImage(from.getWidth(), from.getHeight(), from.getType()); int packedColor = 0; for (int r = 0; r < from.getHeight(); ++r) { for (int c = 0; c < from.getWidth() ; ++c) {
[code]...
So from 0 to 1 (ratio is a double between 0 and 1) the image will "roll up". The effect works completely in the GUI, but the console freaks out at about 0.33 ratio.. This program runs for testing in a class Main and uses a class Splittinimage.. this method is in class TwixPix. When the main class is run, a box pops up with a combo box and a slider. You pick an effect (in this case, roll up) and then slide the slider to set the ratio. The image below those two things performs the effect that was selected. Imagine a PowerPoint presentation slide effect.
Goal this time is to take a charArray, copy it into another charArray while reversing the things in it.
E.g. charArray["!ollaH"] into charArrayNew["Hallo!"]
My first idea was to revert the stuff in the Array with a ! cause i saw earlier that u can work with that too revert booleans. Sadly i didnt happen to make it work.
Next thing i thought of was a for loop to go trough the charArray and copy every section into charArrayNew just at the opposite end.
Java Code:
import java.util.Arrays; public class aufgabe43 { public static void main(String[] asgr){ char[] charArray
[Code] .....
Eclipse doesn't show any errors, and as u told me last time i did include import java.util.Arrays; to output the array in the end.
When i try to compile the code eclipse returns with an error
Java Code:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 68 at aufgabe43.main(aufgabe43.java:8) mh_sh_highlight_all('java');
Which I frankly don't understand since the array . Length is exactly the same.
I'm very new to java code I'm currently learning about loops I've tried to write this for a statement in the program I'm making but its not working. I keep getting this message
LoanQualifier.java:26: error: illegal start of expression if (salary >0||<=250000) ^ LoanQualifier.java:28: error: illegal start of type if (yearsOnJob >0||<50)
I have a servlet that adds entries to a table and when there is a duplicate it redirects to an error page and I'd like to make it display the duplicate entry id.The problem is when I try to get the parameter and show the error (the duplicate entry id) on my jsp error page it shows null instead of the appropriate number.this is my servlet:
It seems that all of my arrays in the class Calculations are out of bounds, and I do not seem to know why.
Java Code:
/** public class DataAnalyzer { public static void main (String[] args) { //This creates an instance of ReadFiles ReadFiles aReadFiles = new ReadFiles(); Calculations aCalculations = new Calculations();
class test{//class public static void main(String[]args) { String booking [][]= new String [30] [6] ;//two dimensional array System.out.println("Enter the seat column you want");//column entry char column=Keyboard.readChar(); System.out.println("Enter the seat row you want");//row entry int row=Keyboard.readInt();
I am having trouble with an array out of bounds exception. I understand what the error means (that I am trying to access part of array that does not exist). But I do not see the error in my code.
Java Code:
public class bubbleSort { public static void main(String []args) { int i; int array [] = {12,9,4,99,120,1,3,10};
I have a 2-D character array and I was wondering if I can compare a given index to an out of bounds index and what would I have to write? For instance
if(array[0 - 1][0 - 1] == 'indexoutofbounds'){ **// I know that 'indexoutofbounds' is probably not the right wording** stuff happens }
If I can do this what would I actually have to write in where it says 'indexoutofbound' ?
I will be using this for many indexes so it wont always be [0 - 1][0 - 1] it could be [4 - 1][3 - 1] in which case it wouldn't be out of bounds and wouldn't move onto "stuff happens"....
I am trying to uncover why I am getting an error message when trying to view a panoramic photo on my wordpress website.We are using the PTviewer plugin.This is the error message when you load the page: URL....I recently took over as webmaster for this site am not sure how the previous developer decided to set this up.Here is the raw code:

I am getting the error message as Exception in thread "main" java.lang.Error: Unresolved compilation problems: NewExcel cannot be resolved to a type for the line NewExcel test = new NewExcel(); in the below code to read the columns from an excelsheet "test.xls".

I am making a very simple 2D array game where the player is asked what size they would like the game board to be. After entering, it displays the board and the player 'P' starts at index [0][0]. After that, they are asked for an action, which can be "up", "down", "left", "right", or "exit". I will be including some extra later (like a treasure at the end, or random obstacles), but for now this is what the game consists of.
I was instructed to "do nothing" when/if the player attempts to go out of bounds. I am trying to simply print an error, such as "Out of bounds! Try again.", then prompt the player again for an action. I even tried to make a boolean method to catch it, but to no avail.
I don't want the exception to occur at all. I just simply want the error message to print to the player and ask for another action. I would prefer not to use try/catch, or try/catch/finally since I already tried that and it still gave the exception error.This program consists of two classes. I will show the class containing the main first, then the client-server type class second.
import java.util.Scanner; public class Driver { public static void main(String[] args) { World world = new World(); boolean keepPlaying; keepPlaying = true; boolean isOutOfBounds; isOutOfBounds = false; int height = 0; int width = 0; int x = 0; int y = 0;
I need to read from a text file given to us that has a list of books with authors names and book titles separated by an @ symbol for our delimiter. Here is the code I have right now, but it throws an ArrayIndexOutOfBoundsException at line 7...and I am unsure why?
import java.io.*; import java.util.*; public class Driver { public static void main(String[] args) { new Driver(args[0]);
[Code] ....
I realize that it must have something to do with my command line argument...but I am unsure what. Am I not entering the file name correctly?
I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code
//import statements import java.util.*; //for scanner class // class beginning public class Guess { public static void main(String[] args ) { //Declare variables area int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;

What's wrong with my Java program? When I open it using appletviewer, the applet opens but stays blank and an error message appears in Terminal.

I am assigned to create a program "Simpletron" that the only language understands it is Simpletron Machine Language or SML. I figured out the most but I get the message "No main methods, applets, or MIDlets found in file" when compiling the program. I pasted my program so that you can see.
