I'm new to java and I write a simple "Five in a row" game. I have a fixed 13*13 board which contains 169 buttons in an arraylist. Everytime player clicks the button the game set a value of 'x' or 'o' to the arraylist name value. And I have a method named isWon() to check if the it is won or not after player click the button. The game sometime gets and index out of bound exception when checking for whose win.
ArrayList<Character> value = new ArrayList<>();
constructor()
{
for (int i = 0; i < 169; i++) {
value.add(' ');

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)) {

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.

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;

The method I have written uses one other method from my code, which is "reverse". Any way to return false without getting this error.
My problem is that I can't even run the program, because it gives me

I created and an Array of integers how can I get randomly get/pick the index of each array element.
View Replies View RelatedI searched online for this error and found out it's because the array is smaller than the index but I am not sure how I can fix this error....

int i = DEFAULT_ZERO;
Lamborghini[] carWithinHPRange = new Lamborghini[i];
for (Lamborghini lambos : inventory){

I tried
Lamborghini[] carWithinHPRange = new Lamborghini[i+5];
//which works sometimes because once I boost up the range and so there'll be more result then the error came up again....
My project was to create an array holding 10 integers and populate the array with 10 random numbers. Then ask the user to guess the number. Prompt the user with a while loop if their input is out of range. Determine if the users number is in the array, and display which index location the number is in. I got most of the code done but am having trouble displaying the index location.

I want to find a certain element in array I have to scan through the array index starting from 0 until I find the number I am looking for. Even in data structures which use hashing like HashMap and Hashtable we will have to scan through the keys until we find the key we are looking for. So what is the use of hashing over index based searching? I mean how is hashing an advantage over an array?

I'm trying to iterate through an array of integers and find the start position of the part of the array containing the most consecutive 1s.
For example given the array {1,3,1,1,1,1,5,3,2,1,1}, the method should return 2 and given {1,4,5,1,1,1,5,1} the method should return 3.
So far, I've managed to retrieve the element where the consecutive 1s begin. However, I'm unsure how to get the index of this element and this implementation doesn't work if there is more than one set of consecutive 1s.
public class GetIndex {
public static int getPosition(int[] myArray) {
int index = 0;
int tracker = 0;
int mostOnes = 0;
