I already added the background file under the project file but the image is not added to the GUI.
I am very new to JAVA so maybe this is a silly mistake but I really hope somebody can help me with this. I tried other methods but most will give me errrors only this version of code that can rude but the image is not added at all.

How can I clear the JTextField and have it ready for input immediately without requiring a click or other action?

I posted my full code below so you guys could have a solid understanding of what I want. When I click send, the text field clears but is not ready for input. I have to click for the input. I want it to be ready for the input immediately and textfield.setText("") will not work. Any ideas?

To focus text field after setText(""); method you can use the following,
textFieldName.requestFocus();
To center the text field you can use this code,
textFieldName.setHorizontalAlignment(JTextField.CENTER);

Calculator Can't have Decimal

actionPerformed is parsing its inputs as int and operating on them as such. If you want to use floating-point numbers, try using double instead.

Parsing as an integer cannot handle double's or any floating point number (decimal) as such change your actionPerformed to parse double's instead or parse int's:
public void actionPerformed(ActionEvent e) {
if (e.getActionCommand().equals("Sum")) {
ansLabel.setText("" + (Double.parseDouble(num1Text.getText()) + Double.parseDouble(num2Text.getText())));
}
else if (e.getActionCommand().equals("Subtract")) {
ansLabel.setText("" + (Double.parseDouble(num1Text.getText()) - Double.parseDouble(num2Text.getText())));
}
else if (e.getActionCommand().equals("Multiple")){
ansLabel.setText(""+(double)(Double.parseDouble(num1Text.getText())*Double.parseDouble(num2Text.getText())));
}
else if (e.getActionCommand().equals("Divide")){
ansLabel.setText(""+(Double.parseDouble(num1Text.getText())/Double.parseDouble(num2Text.getText())));
}
}

You use
Integer.parseInt(num1Text.getText());
which parses a String to an int.
With
Double.parseDouble(num1Text.getText());
you get a double.
Note that you might want to catch the NumberFormatException, since you most likley don't want your program to stop on malformed user input:
double num1;
try
{
num1 = Double.parseDouble(num1Text.getText());
} catch (NumberFormatException e)
{
// either use a default value or give feedback to the user on what he did wrong
// for example
num1 = 1;
}
If you don't want to print a double value, if only integer values are entered by the user, then you could first try to parse to int, catch the exception (if any) and then parse to double.
Another error in your divison line:
ansLabel.setText(
""+(Integer.parseInt(num1Text.getText())/Integer.parseInt(num2Text.getText())));
You do not check if the second parameter is != 0, otherwise you might divide by 0!
To keep your code more readable you might want to create an extra method for parsing a String to a number:
private static double parseDouble(String s)
{
double num;
try
{
num = Double.parseDouble(num1Text.getText());
} catch (NumberFormatException e)
{
// either use a default value or give feedback to the user on what he did wrong
// for example
num = 1;
}
return num;
}
A possible fix for the division by 0 could be:
double num1 = parseDouble(num1Text.getText());
double num2 = parseDouble(num2Text.getText());
String command = e.getActionCommand();
if (command.equals("Sum"))
{
ansLabel.setText("" + (num1 + num2));
} else if (command.equals("Subtract"))
{
ansLabel.setText("" + (num1 - num2));
} else if (command.equals("Multiple"))
{
ansLabel.setText("" + (num1 * num2));
} else if (command.equals("Divide"))
{
if (num2 == 0)
{
ansLabel.setText("ERROR: Division by zero!");
} else
{
ansLabel.setText("" + (num1 / num2));
}
}

you should use double data type instead of integer for 4 operations

Like this:
public void actionPerformed( ActionEvent e )
{
if( e.getActionCommand().equals( "Sum" ) )
ansLabel.setText( "" + ( Double.
parseDouble(num1Text.getText() ) + Double.parseDouble(
num2Text.getText() ) ) );
// etc.

event mouseclicked in java not working to populate text field

I am making a gui with netbeans. I right clicked a JTable to add event listener for mouse clicked. I added my code to the new method. For the life of me when I click the JTable I get no errors.
Any ideas on what I am doing wrong or how to fix it? if you need to see more of my code let me know. everything besides the connection to the DB is ran out of the driver class.
I moved my program to eclipse to make this easier for me to trouble shoot.
private void tableDisplayMouseClicked(java.awt.event.MouseEvent evt) {
try {
int row = tableDisplay.getSelectedRow();
String tableClick = (tableDisplay.getModel().getValueAt(row, 1).toString());
String sql = " select * from contact where id = ' " + tableClick + " ' ";
pst = conn.prepareStatement(sql);
rs = pst.executeQuery();
if(rs.next()) {
System.out.println("hey dude this method is being called.");
String add2 = rs.getString("Business_Name");

It's difficult to know why you're having issues with the registering a MouseListener, there's not enough context to diagnose the problem.
You should start by placing out put statements in the code to check to see if the method is been called and that the query is returning values.
If all else fails, you should try regsitering the mouse listener manually. See How to Write a Mouse Listener for more details.
You query is also including spaces in the match...
String sql = " select * from contact where id = ' " + tableClick + " ' ";
^------------------^-----
Which will affect the ability for the database to match results to your query. Try removing these
String sql = " select * from contact where id = '" + tableClick + "'";

GRADING SYSTEM using JComboBox for the entry of grades; Jlabel, JTextFirld,JFrame; JButton for events; all in JFrame

here is my code for our finals. a grading system were the grades are all in 24 JComboBox. some with numbers till 10, 20 and 30. each quarter they are computed and shown in a JTextfield. when the four quarters are complete a Jbutton "COMPUTE ALL" calculates the entire data and will show in another frame the student's grade and weather he or she have passed or failed. this code works good with some problems: (1) my Jbutton "CLEAR ALL" doesn't work. it should show the default number "0" when clicked and the Jtextfields must be empty-(THIS ALREADY WORKS "TEXTFIELD TO EMPTY". (2) i want to hide the second frame when the Jbutton for compute all is clicked (f2.hide();f3.show();) but it keeps saying (cannot find symbol
symbol: variable f2cannot find symbol) (3) and lastly in my 3rd frame where the student's final grade and final rating are shown i cant really have it shown in a message dialog stating weather he or she passed or failed. THANKS. sorry for the poor coding.

These were the problems,
1.When you give zero in quotes like "0" its taken as string, whereas Integer is what required.
2.The jFrame f2 was not accessible because it was defined inside another action event.
3.The same was the problem with the variable equiv, thats why it was not accessible in the event of jOptionpane.

Write to text file through a java GUI

I have created a java GUI that works as a 6-question questionnaire. For each of the six question, I have 4 choices , i, ii, iii, iv for the user to choose, and then type out one of the four choices in a text box, then click a button "enter" to go to the next question. After all six questions have been answered, it will jump to a finish page.
I want to write the input value (in the text box) of each question to a text file. So After clicking on the "enter button" to answer all six questions I can see something like "i ii iii i ii iii" in a text file.
Is there a way to do it?
