Code is supposed to count number of Words in a String between A-Z and a-z, i am aware there are many methods to do this more efficiently, but i would prefer to do it using the methods shown.
class
// Purpose : 1) Write a program which will input a string from the
//keyboard, and output the number of separate words,
//where a word is one or more characters separated by
//spaces. Your program should only count as words groups
//of characters in the ranges A..Z and a..z

Ok, so I'm just trying to write a basic little program that reverses the letters in someone's name. I thought I had it down, but I guess not. Here's the code, and the error I'm getting is:
java.lang.StringIndexOutOfBoundsException: String index out of range: 11 (in java.lang.String) (11 is the length of the name I'm inputting) import java.io.*; import java.util.*;
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));
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 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 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)+" ");
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;
My problem is that I can't even run the program, because it gives me

I have an issue with an IndexOutOfBoundsException. I am trying to populate a db from another using arraylists and arrays. I can get the data but the program fails when trying to run the inserts. I am trying to perform SQL in batches of 5. I have added a comment to the failing line.
/*Set in code at beginning*/ ArrayList<String[]> privacyList = new ArrayList<String[]>(); ArrayList<String[]> statementBuffer = new ArrayList<String[]>();
/*Some sql is performed and the following String array is populated*/ while (rs.next()) { String[] row = new String[55]; resultSetIsEmpty = false; row[0] = rs.getString("ID");
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};
I have been trying to get this method to work for a few hours now, for some reason I get an IndexOutOfBounds exception every time. Basically I am trying to read a txt file and add the words to an ArrayList as strings separated by a space .
private ArrayList<String> readLinesFromFile(BufferedReader inputFile) throws IOException { String value = null; ArrayList<String> result = new ArrayList<String>(); while((value = inputFile.readLine()) != null){ String[] values = value.split(" "); for (int i = 0; i < values.length; i++){ result.add(values[i]); } } return result; }
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?
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 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 'm trying to draw a button by resizing a simple button background image to fit the size of the text. Everything works well except for the actual drawing of the string. The y value that I give the Graphics object designates the baseline, however I would like to draw the the string above the y. So that the image below doesn't happen.
I gave the graphics object the y of the bottom of the "P" and would instead like to give it the value of the bottom of the "y". Is there a way to do that by reading the String's bounds or something, or is there a way to get the Graphics object to use the passed y value as the definite bottom of the String?
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;
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();
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[][];
The code is supposed to insert HTML formatting on a specified string. (i.e o<b>the</b>r )Most of the code works correctly as I verified the outputs without a while loop. The loop is causing a string out of bounds error. I've tried adding the if statement and also formatting the (result += line) nothing is getting appropriate results...
public static String addFormat(String webpage, String toMatch, String format) { String result = ""; String insert = ""; format = format.toLowerCase(); switch (format){ case "bold": insert = "<b>" + toMatch + "</b>";
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};
