Reading From Text File - Array Index Out Of Bounds Exception

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?

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?

Index Out Of Bounds Exception

Jul 13, 2014

I can't even run the program, because it gives me index out of bounds exception but what exactly went wrong.

I feel that even after it's able to run it will be totally wrong, but one thing at a time /*Write a method called longestSortedSequence that accepts an array of integers as a parameter and returns the length of the longest sorted (nondecreasing) sequence of integers in the array.

For example, in the array {3, 8, 10, 1, 9, 14, -3, 0, 14, 207, 56, 98, 12}, the longest sorted sequence in the array has four values in it (the sequence -3, 0, 14, 207), so your method would return 4 if passed this array. Sorted means non-decreasing, so a sequence could contain duplicates. Your method should return 0 if passed an empty array.

*/ public class ten {
public static void main(String[] args) {
int[] arr = {3, 8, 10, 1,9, 14, -3, 0, 14, 207, 56, 98, 12};
longestSortedSequence(arr);
System.out.println(longestSortedSequence(arr));

2D Character Array - Can Compare To Index Out Of Bounds?

Nov 11, 2014

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"....

Array Index OutOfBounds Exception While Moving Creature Through 2D Array

Oct 13, 2014

I am receiving an ArrayIndexOutOfBoundsException for the following code, which moves a creature through a 2D array maze. I have altered the clauses of the first if statement for the four direct methods (north, south, east, and west) multiple times (i.e. x + 1 >= 0 && x > 0 && x - 1 > 0 && x < array.length...etc). However, while the code occasionally runs, more often than that it returns this exception. Catching the exception seems like a poor workaround though if worst comes to worst I'll do that.

I included only the relevant functions of the code:

public boolean goNorth(char[][] array) {
boolean success = true;;
x = getX();
//x = this.x;
y = getY();
//y = this.y;
if ((x - 1 >= 0 && x - 1 < array.length)
&& (y >= 0 && y < array[x].length)) {

Creating Conway Game Of Life - Index Out Of Bounds?

Mar 3, 2015

The question pretty much says it all. My problem seems to be when adding the neighbours, I am always getting a Index out of Bounds problem. I know this is because the code is reaching for the edge of the table, for example if the column, i = 0 and the statement says to perform i - 1 and return it, then we are going to have a problem.

Similarly with anything like j = 20, j + 1 (as the grid only has 20 spaces). I understand the problem, but I am unsure of how to solve it. I have tried messing around with the if statements, but I continue to get the 'out of bounds' problem...

import javax.swing.*;
public class GameOfLife {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
int cellChoice = 0;
int newCells = 1;
int generation = 1;
int neighbours = 0;

Sort And Match Items In A Collection Of Arrays - Index Out Of Bounds

Apr 8, 2015

I am working on a class that sorts and matches items in a collection of arrays. In the end, elements common to all 3 arrays should be printed. The idea is that as the first array is compared to the second it stores the matched items in tempArray. When all items are compared the tempArray should overwrite the checked array, and the process continues until all arrays are checked. I have set all the checking in a do loop that should run while the value is <= to the array length. This allows all items in the reference array to be checked. I get an index out of bounds message but not where I would expect it. I have tried varying the condition in the do while loop in the match method, but it did not change the result. There may be other issues I have not addressed with solving the algorithm, but this one has me stumped and I am not able to progress.

package testing;
public class TestMatchMain {
public static void main(String[] args) {
Comparable[] innerCollection0 = {1,2,3,4,5};
Comparable[] innerCollection1 = {1,1,5,6,7};

Airline Two Dimensional Boolean Array

Feb 23, 2015

I have a boolean array that looks like this

boolean seat[][] = new boolean[2][3];

I reserved one row for first class and another for economy class. This code works just as I want but my question is how can I loop through it so I don't need all the if statements? I tried it many ways. I tried something like this but I cant get it to work.

for (int row=0;row<seat.length;row++{
for (int col=0;col<seat[row].length;col++){
if (seat[0][col]==false){
seat[0][col]=true;
System.out.println("You have number 0" + row + in first class);

How To Avoid String Index OutOfBounds Exception

Feb 16, 2015

The method I am trying to successfully write is startsWith(String s1, String s2)

The intention of the code is to return true if s2 starts with the string s1, and false otherwise. For example,

x.startsWith("Maplestory","Maple"); Should return true.

This code partially works, depending on the values entered into it. When it is supposed to return true, it does do this. When it is meant to return false, I get a StringIndex OutOfBounds Exception.
 
public class CC02{
String remove1(char c, String s){
String to_return="";
while(true){
if(s.equals(""))
return to_return;

[Code] ....

The method I have written uses one other method from my code, which is "reverse". Any way to return false without getting this error.

Char Array Goes Out Of Bounds

Jan 16, 2014

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.
