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));

Finding Longest Zig-Zag Sequence In Array

Oct 26, 2014

From a given array of positive and negative numbers, I have to find the longest SUB-Array which represents a Zig-Zag sequence...

A Zig-Zag sequence means that one number is possitive, the next one negative, the next one possitive, and so on and so on...

Like this: -1, 4, -5, 6, -9, 2, -9 etc....

So that means, if the array looks like this:

1, 4, -2, -5, 6, -9, 1, -4, 9, -8, 7, 4, -3

the longest sub-array which fulfills the requirement is (the part in bold):

1, 4, -2, -5, 6, -9, 1, -4, 9, -8, 7, 4, -3

and I only need it's length, which in this case is: 8

Finding Longest Increasing Sequence Not Giving Proper Result

Jan 28, 2015

Okay so I need to be able to read a file and then be able to find the longest sequence of increasing numbers.

So if the file was this, (this is Ass1Q2_test4.txt)

97 47 56 36 60 31 57 54 12 55
35 57 41 13 82 80 71 93 31 62
89 36 98 75 91 46 95 53 37 99
25 45 26 17 15 82 80 73 96 17
75 22 63 96 96 36 64 31 99 86
12 80 42 74 54 14 93 17 14 55
14 15 20 71 34 50 22 60 32 41
90 69 44 52 54 73 20 12 55 52
39 33 25 31 76 45 44 84 90 52
94 35 55 24 41 63 87 93 79 24

the output should be,

(5,0) with cost 12
(6,0) with cost 14
(6,1) with cost 15
(6,2) with cost 20
(7,2) with cost 44
(7,3) with cost 52
(7,4) with cost 54
(6,3) with cost 71
(5,3) with cost 74
(4,3) with cost 96

Greatest path is of length 10.

Now, the code that I have works, kind of. Instead of recurring several times at each point, it only recurs once.

So say I'm looking at (1,1). With (1,1) being 57. The area around it looks like this.

97 47 56
35 57 41
89 36 98

Now when I look at it, there are several paths it can take. It can go 57, 97 or 57, 89 or 57, 98. However, I'm pretty sure that it just uses the first one that corresponds with the first if statement that is valid. So I start checking north of the value, then northeast, then east, then southeast, which at southeast is where I find my first greater than value. After it finds it's first valid number, it then continues from that number, instead of checking if there are other longer paths stemming from the original value.

In conjunction with that, you can see that the printout just returns all paths from each value. Which isn't what I want. I need a way to store the longest current path, then check each path after to see if it's longer. If it is, it's replaced, if not, it stays the same.

I've also attached Ass1Q2_test4.txt

JCF Show Sorted Table With Index

I am new to java or at least the collection series. My job is to make a method like this:

public void frequency(int[] arr)

And should contain numbers like: [ 2,5,2,9,7,1,100,2,3,5,77,9,1,2,6,5 ]

Now the next part i should sort the tabel and show how many times each number shows in the array:

with the index.

What is the best easiest way in collection?

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"....

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};
