i am a beginner in java, and i am trying to understand the problem in what my friend wrote, the problem from what i think is that the array size are different. if anyone can help it would be much appreciated.
the problem

and here is where i think the problem is
public void actionPerformed(ActionEvent e)
{
Random randomNumbers = new Random();
studentarray = new Object[numofstudent];
quizarray = new Object[numofstudent][numofquiz]; //quizarray = new int[numofstudent][numofquiz]; (original)
for(int i=0; i<numofstudent; i++)
{
quizarray[0][i] = baseid+i;
System.out.println(quizarray[0][i]);
//studentarray[i] = baseid+i;
for(int j=1; j<numofquiz+1; j++)
{
int number = randomNumbers.nextInt(100);
quizarray[j][i] = number; // row column
System.out.println(quizarray[j][i]);
}
}
You define:
quizarray = new Object[numofstudent][numofquiz]
But then access it using
quizarray[0][i]
Where i is < numofstudent. I think you just want:
quizarray[i][0]

I am trying to create a simple program just using the built-in Math methods, but everytime I run it I get a floating decimal error, so I wonder what a floating decimal is and how error occurs.
Here is my code:
private void btnCalculateActionPerformed(java.awt.event.ActionEvent evt) {
double dblSquareRoot = Double.parseDouble(lblSquareRoot.getText());
double dblRandomNumber = Double.parseDouble(lblRandomNumber.getText());
double dblSquareNumber = Double.parseDouble(lblSquareNumber.getText());
double dblRoundUp = Double.parseDouble(lblRoundUp.getText());
double dblRoundDown = Double.parseDouble(lblRoundDown.getText());
lblOutputSquareRoot.setText("" + Math.sqrt(dblSquareRoot));
lblOutputSquareNumber.setText("" + Math.pow(dblSquareNumber, 2));
lblOutputRoundUp.setText("" + Math.ceil(dblRoundUp));
lblOutputRoundDown.setText("" + Math.floor(dblRoundDown));
}
private void btnGenerateActionPerformed(java.awt.event.ActionEvent evt) {
double dblRandomNumber = (Math.random() * 101.0);
txtRandomNumber.setText("" + df.format(dblRandomNumber));
txtSquareRoot.setText("" + df.format(dblRandomNumber));
txtSquareNumber.setText("" + df.format(dblRandomNumber));
txtRoundUp.setText("" + df.format(dblRandomNumber));
txtRoundDown.setText("" + df.format(dblRandomNumber));
df.format = "###.00";
}

It looks like you're trying to parse strings from the labels instead of the text fields. Take a look at the variable names.
Here is the code of mouse entered event of label 1 . And the exception is occuring .I have already worked on previous version but I don't why this happening now.
private void jLabel1MouseEntered(java.awt.event.MouseEvent evt) {
ImageIcon n_cig;
n_cig = new ImageIcon(getClass().getResource("masterproject/Cfull.png"));
jLabel1.setIcon(n_cig);
}
private void jLabel1MouseExited(java.awt.event.MouseEvent evt) {
ImageIcon n_cig;
n_cig = new ImageIcon(getClass().getResource("masterproject/No Cigarretes.png"));
jLabel1.setIcon(n_cig);
}
And the exceptions are here

The reason that you get a NullPointerException is because for some reason the image file that you're trying to specify cannot be located. So the getResource() method returns a null.
Create a utility function to handle these kind of exception in future
public ImageIcon createImageIcon(String path,
String description) {
java.net.URL imgURL = getClass().getResource(path);
if (imgURL != null) {
return new ImageIcon(imgURL, description);
} else {
System.err.println("Couldn't find file: " + path);
return null;
}
}
Check using this function that wheather or not you are able to access the image or not
I'm Trying to run this code to get the ResultSet row by row into an Array so i can put them in a jTable. I don't get why i get this error, i'm new in this.
I would be totally thankfull if you could help me.
try {
int pos = 1;
for (int r=0;r<rsCount;r++){
String[] na = null;
res.absolute(pos);
int a=1;
while(res.next()){
na[a]=res.getString(a+1);
a+=1;
}
pos+=1;
for(int c=0;c<8;c++){
tabla.setValueAt(na[c], r, c);
}
}
} catch (SQLException ex) {
Logger.getLogger(Reporte.class.getName()).log(Level.SEVERE, null, ex);
}
}

Your string array is not being properly instantiated. You need to instantiate it like:
String[] na = new String[100];
If you don't know how big the array is going to be you might want to consider using an ArrayList
ArrayList<String> na = new ArrayList<String>();
then each string can be added with:
na.add(res.getString(a+1));
I have had a few problems trying to get this table to show in NetBeans. Here is the code that I am trying to use. I am aware that the loop is wrong and will fix that at a later date.
I get a runtime error with the following code and I can't work it out.
Object[][] data = null;
String[] columnNames = {"Type", "Grade", "Height", "Width", "Length", "Reinforced Bottom", "Reinforced Corners", "Sealable", "Quantity"};
JTable table = new JTable();
public void showTotalOrder(){
for(int i=0; i<boxes.size(); i++){
for(int j=0; j<1; j++){
data[i][j] = boxes.get(i).getName();
data[i][j+1] = boxes.get(i).getGrade();
data[i][j+2] = boxes.get(i).getHeight();
data[i][j+3] = boxes.get(i).getWidth();
data[i][j+4] = boxes.get(i).getLength();
data[i][j+5] = boxes.get(i).getReinforcedBottom();
data[i][j+6] = boxes.get(i).getReinforcedCorners();
data[i][j+7] = boxes.get(i).getSealable();
data[i][j+8] = boxes.get(i).getQuantity();
}
}
JOptionPane.showMessageDialog(this, table);
}
I believe the problem is with the last line of this method.
The error i receive is:

Given this stack trace:

...
You get a NullPointerException because of data array is initialized to null:
Object[][] data = null;
Please have a read to:
What is a Null Pointer Exception, and how do I fix it?
Creating, Initializing, and Accessing an Array
Good time, everyone. I have a bad issue in my code. When I compile it, it doesn't works like I expected and returns me too many exceptions.

First one at kazemirdo.KazemirdoMatcher.KazemirdoMatcherAct(KazemirdoMatcher.java:53) refers:
public void KazemirdoMatcherAct() {
requestWords = kC.getRequestBuffer();
int j = 0;
// Searchs the matches
for (String match : requestWords) { // Refers right here.
p = Pattern.compile(match + "\t.*");
for (int i = 0; i < morphBuffer.length; i++) {
if (morphBuffer[i] == null) {
buffer[j] = morphBuffer[i+1];
}
else {
m = p.matcher(morphBuffer[i]);
if(m.find()) j++;
}
}
}
}
Second exception refers to place, when I'm calling KazemirdoMatcherAct() method.
But others.. I can't understand, really.
What I do wrong?
Whole code, if needed: http://fpaste.org/62123/18201713/
Maybe you can System.out.print the requestWords in KazemirdoConverter,see what is the String request.
