Null Pointer Exceptions On First Attempt At JButtons

Dec 12, 2014

I am designing/coding a blackjack GUI program and I'm trying to add function to my JButtons. Problem is, I now have 2 NullPointerExceptions.

public class GameConsole {
Player user;
Player dealer;
Deck playingDeck;
ValidateInput validate = new ValidateInput();

[Code] .....

I am trying to do. I am getting the following exception/stack trace at line 14 in userTurn()

Exception in thread "main" java.lang.NullPointerException
at blackjackControls.GameConsole.userTurn(GameConsole.java:163)
at blackjackControls.GameConsole.gamePlay(GameConsole.java:87)
at blackjackControls.Main.main(Main.java:7)

and then the program continues and after I click the button I get :

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at blackjackControls.GameConsole.userTurn(GameConsole.java:163)
at blackjackControls.ResultPanel$1.actionPerformed(ResultPanel.java:34)
at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2028)
//and then about 30 more "at" lines

Why am I getting these exceptions and how do I fix it?

Program A Star Algorithm Using JButtons - Null Pointer Error

May 30, 2014

I am trying to program the A star algorithm using JButtons. Now I have some tweaking to do but I have to get past the errors first.

I am getting the following errors:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at AStar.findEndButton(AStar.java:40)
at Screen$1.actionPerformed(Screen.java:59)
at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018)
at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2341)

[Code] ....

In my AStar class you will see these buttons which is an instance of matrixButtons

MatrixButtons[][] current;
MatrixButtons[][] endButton;
MatrixButtons[][] startButton;
MatrixButtons[][] nextCurrent;
MatrixButtons[][] temp;
MatrixButtons bestNextMove;

I really need them to handle several different methods. A full example of the full program is below.

import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
 
import javax.swing.*;
public class Screen

Null Pointer Error

Oct 15, 2014

So I'm trying to add two numbers using a stack class I made myself. I have a main class with a main method in which I use three stacks on holds one number one holds the other and then I sum one digit at a time keeping in midn that there may be a carry before putting the result on a third stack.

My problem is I'm getting a null pointer error when it should be putting an integer into the top of my stack which is index 0, I've checked my code and can't see why it would be doing this.This is my main method in my main class

import java.util.*;
import java.io.*;
public class CS25driver {
public static void main(String[]args) throws FileNotFoundException {
 
[code]...

my input file looks like a single line of input stating the problem followed by two lines of input which need to be summed.this is the error I'm getting

Exception in thread "main" java.lang.NullPointerException
at StackClass.push(StackClass.java:38)
at CS25driver.main(CS25driver.java:55)

Another Null Pointer Exception

Aug 14, 2014

It is supposed to create an array of random strings and sort them according to their HTML numbers. It creates the array correctly and even compiles correctly, but has a null pointer exception when it comes to the sorting. (I have cut out other parts of the program that were irrelevant).

the lines that produces the null Pointer Exception is line 24. if(array[i].charAt(0)>array[maxIndex].charAt(0))...and 53.stringSelectionSort(stringArray);

import java.util.Arrays;
import java.util.Random;
/**tests the array.sort() subroutine vs. a
'selection sort' that I will write. a random list
of integers is used first and times are recorded to
determine which one is more efficient. A random list
of strings is also tested.**/

How Should Null Pointer Exception Be Avoided In A Program

Aug 6, 2014

How should null pointer exception be avoided in a program. Should each and every place of access of a variable be checked for null and if null is there own customized exception should be thrown. Is this approach correct for avoiding null pointer exception.

Null Pointer Exception When Trying To Write To File

Aug 14, 2014

I've been closely following a tutorial series, and as far as I can tell my code is exactly the same, but not functioning.

The app throws a nullpointer exception here on "controller.saveToFile(fileChooser.getSelectedFile ());"

// Export data item
exportDataItem.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if (fileChooser.showSaveDialog(MainFrame.this) == JFileChooser.APPROVE_OPTION) {
try {
controller.saveToFile(fileChooser.getSelectedFile());

[Code] ....

There are no errors popping up in the code, and I dont understand why there is a null pointer exception when Im saving this file.

Prevent ComboBox From Being Used - Getting Null Pointer Exception

Should the piece of code below set prevent the comboBox from being used? All it does at the minute return a null pointer exception.

I want it to be true if it equals export which is does and it's populated fine but when I try and hide it if the condition equals import it returns a null pointer?

CompareTo Statement - Null Pointer Exception

Apr 16, 2014

I am getting a NullPointerException at my compareTo statement in this section of my code. Why this is popping up?

public static int findPos(String theArray[], String playerName, int arrayCount)
{
int index;
int pos;
for(index = 0; index < arrayCount; index++) {
while ((index < arrayCount) && (playerName.compareTo(theArray[index]) > 0)) {
index++;
}
}
pos = index;
return pos;
}

Error is also creeping up on the line highlighted in a comment as "THIS LINE", and is linked to the compareTo error above.

while(yesOrNo == 'Y' || yesOrNo == 'y')
{
switch(option)
{
//Add a Player and their Stats to the Array

Go Fish Program And Null Pointer Exception

Mar 23, 2015

I'm new to Java programming (taking a beginner's class) and our assignment is to program a game of Go Fish. I've got all my classes written (Card, CardPile, Player and GoFish). Now the problem is that I'm getting a NullPointerException when I run the GoFish class. The error seems to occur when I ask the program to check whether the player whose current turn it is, has a book (meaning 4 cards of the same value) in their hand. My idea was to run through the values 1 to 13, first checking to see if the value appeared in the player's hand:

if(players[currentTurn].hasCard(hasValue))

And if true, then remove all the cards matching the value from the player's hand, add to a new array of cards and then check to see if this array is of length 4 i.e. a book. If not, return the array of cards to the player's hand.

Here's the error message:

java.lang.NullPointerException
at CardPile.searchValue(CardPile.java:88)
at Player.hasCard(Player.java:15)
at GoFish.main(GoFish.java:98)

It references the following lines of code:

In GoFish.main:

// At the end of each turn, check to see if player currentTurn has made a book.
boolean hasBook = false;
int hasValue;
for (hasValue = 1; hasValue <= 13; hasValue++) {
// Runs through player's hand and removes all cards of the same value between 1 and 13 and places in a new array.

[Code] ....

I cannot figure out why I am getting the null pointer exception error!!!

Run Time Error As Null Pointer Exception While Compiling

Apr 12, 2015

I have an input text file as file.txt where, it consists of only real values separated with commas, and arranged as rows as columns as mentioned below :

1,2,3,4,5,6,10,5,8,9
1,4,7,8,9,0,6,4,3,2,1
2,4,5,8.1.3.4.6.7.9.0

the number of rows is 100 and the number of columns are 9, that is they are fixed.Above is just an example, the file consists of decimal values.What I require is for each column of values I need to find out it's average or mean, that is in above example,

for 1st column:(1+1+2)/3
for 2nd column(2+4+4)/3
for 3rd column(3+7+5)/3,,,,,,,like this till the last column.

So I need to take the input from the .txt file, calculate the column average of each column and the average of each column must be displayed as output. I have done a bit of coding, but it is giving a run-time error as NullPointerException.I will forward my code as attachment, the reading of file, is done as string in java and then it must be converted to double values, also to read the comma separated input from a file I have used the split().

Swing/AWT/SWT :: Null Pointer Exception When Retrieving Data From Table

Mar 31, 2015

I am trying to export data from a jtable to a pdf report but every time i try running the code it gives me this exception:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at GUI.QC_receiving_book.printButtonActionPerformed(QC_receiving_book.java:309)
at GUI.QC_receiving_book.access$600(QC_receiving_book.java:26)
at GUI.QC_receiving_book$7.actionPerformed(QC_receiving_book.java:165)
at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2018)

[Code] ....

I tried avoiding the null exception by using the if statement but it didn't work. The row I choose from the table is full meaning there are no empty attributes. and all the data are imported from a mysql database to the table as String so there can't be any casting errors.

This is the part of the source code with the problem and i will also post the printing method. I tried debugging the class and when stepping into the first if statement it opened the jTable.java file and pointed at the getSelectedRow() method and this sentence "variable information not available.source compiled without -g option"

private void printButtonActionPerformed(java.awt.event.ActionEvent evt) {
if(samplesTable.getSelectedRow() >= 0){
int row = samplesTable.getSelectedRow();
System.out.println(row);
for(int x=0;x<samplesTable.getColumnCount();x++){
String value = samplesTable.getModel().getValueAt(row, x).toString();

Remove All Numbers From Queue And Push Onto Stack Until Operator Is Reached - Null Pointer Exception

Apr 26, 2015

This method keeps throwing a NullPointerException. Not only that, but its not doing what I want it to do.

Heres the code:

/*
Remove all the numbers from the queue and push onto the stack until an operator is reached
*/

private static void processQueue() {
// Check what is at the front of the queue. If an operator is found or the queue is empty, exit method.
while(queue.front() != null || !queue.front().equals("*") || !queue.front().equals("/") || !queue.front().equals("%")
|| !queue.front().equals("+") || !queue.front().equals("-"))
{
stack.push(queue.removeFront()); // push the operand onto the stack
}
}

Here is the method that calls the processQueue() method

/*
Process the mathematical expression using a stack and a queue
*/
private static double processExpression() {
// insert all elements from the stack to the queue for processing
while(stack.top() != null) {
queue.insertBack(stack.pop());
