How do you select CSV file to perform calculations on based on user input?

I'm currently making a user-input based program on Java Eclipse that is supposed perform calculations on data from a local csv file the user selects. The GUI code below is the source code that I have been using to make the GUI for the program. While I have managed to create the GUI, I am having trouble with "combining" the code listed under "CSVReader," which is a class I created, with the code for the GUI so that the user can select the CSV file. The user is supposed to select this CSV file by typing its path name into the text field box on the GUI.
Any help would be appreciated

is the method to create simple login wrong

I am a newbie in Java GUI development and I am stuck in the following code.
I am open to suggestions. I am actually trying to create a simple login that gives OK if the password is matched to the number 3124, and otherwise shows the error message. Please help me.

}
}
});
}
/**

}
/**

frame.getContentPane().add(btnNewButton_1);
username = new JTextField();
username.setBounds(227, 11, 128, 39);
frame.getContentPane().add(username);
username.setColumns(10);
password = new JTextField();
password.setBounds(227, 76, 128, 39);
frame.getContentPane().add(password);
final int num;
num=Integer.parseInt(password);
password.setColumns(10);
JButton btnNewButton = new JButton("login");
btnNewButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
if(num==3124)
{JOptionPane.showMessageDialog(null, "correct");}
else
{JOptionPane.showMessageDialog(null, "wrong");}
}
});
btnNewButton.setBounds(62, 181, 123, 56);
frame.getContentPane().add(btnNewButton);
}
}

You were checking the password even before the user has had the chance to enter anything into the text box. You need to get and check the value of num in the event listener code i.e. in actionPerformed. Also, don't convert the password to int (someone may enter some non-numeric string).
This code below works better.

try {

window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public Testing() {
initialize();
}
/**

*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);

I know its a long one. I've tried to look through the code but I'm not that experienced with Java or coding.
I don't know why the errors there or what to do so if you could help it would be appreciated a lot by a beginner!

I suggest using a good editor or IDE. Any decent editor should allow to "go to matching parenthesis". For example, if you use vi, position the cursor on a brace and type "%" to go to the matching one. You can use this to verify that parenthesis are matching as you expect.
IDEs such as Eclipse or IntelliJ allow you to reformat code, which will also help you spot where you're missing a closing brace. They also offer other invaluable features when programming in Java, so I strongly suggest spending the time to install and learn one.
This said, you're missing a close brace right before the "And here" comment.

You should use an IDE in order to be able to indent your code and see any missing curly braces.

If you use auto-indent from your text editor, you notice that the last '}' is still indented by one tab.
It means there are more { than }.
With a good IDE (e.g. Eclipse) it's easier to find out where it should be added (Once at the end, once before the last /* And here */ comment). Note that the first error shown by Eclipse isn't the right location in this case.

PS: If you just want to use a basic text editor, Java is the wrong language. Either use Java + full IDE (Netbeans or Eclipse), or Ruby/Python with pluma/notepad2/vim/...

The problem, as many others have suggested here, is in the balancing of the braces, meaning each { opens a block of code and thus needs a matching } to close that block of code.
IDEs do make it easier to do this matching for you, many free text editors are available to do this matching for you.
So a few changes to your code:
This line }/* And here*/); delete /* And here*/ and replace it with }.
Next, the main class public class Password needs to be closed on the last line with a }.
Lastly, since the btnEnter2 needs to override the addActionListener abstract method, you have a typo in line public void actionPreformed(ActionEvent e) {, actionPreformed should be spelled actionPerformed to successfully override the addActionListener anonymous method.
The final code should resemble:

Insert } at the start of line 122 and at the end of code to complete classBody.
But you should really consider Roberto Attia's suggestion.

First of all, class names and constructors should start with an upper case letter, like you did it for class Menu, but not for class convert.
A Java programm should have just one and only one main method for all classes. So, delete complete your main method from Convert class, put new Convert(); in the actionPerformed() method of btnConvert in Menu class:
btnConvert.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
new Convert();
}
});
and add frmTitle.setVisible(true); to the end of the initialize() method of Convert class.

First, your class names should begin with a capital letter, so instead of "convert" it should be "Convert.
Create a public method in Convert:
public JFrame getFrame() {
return frmTitle;
}
Then in your button's actionPerformed() method, just:
Convert w = new Convert();
w.getFrame().setVisible(true);

Java GUI not appearing correctly in IDE

I am using windows 8, 64 bit.
I am learning GUI in Java. Generally I use eclipse IDE. I have also installed Net-beans.
I am trying to do a simple GUI program which will add two number and show their result. But the problem is that when I am running the program from IDE it is looking like this. . But when I am running this same class file from command line it is showing correctly. I have test the same code in both eclipse and Net-beans. But the result is same.
Source code for first picture.
import javax.swing.JOptionPane; // program uses JOptionPane
public class Addition
{
public static void main( String[] args )
{
// obtain user input from JOptionPane input dialogs
String firstNumber =
JOptionPane.showInputDialog( "Enter first integer" );
String secondNumber =
JOptionPane.showInputDialog( "Enter second integer" );
// convert String inputs to int values for use in a calculation
int number1 = Integer.parseInt( firstNumber );
int number2 = Integer.parseInt( secondNumber );
int sum = number1 + number2; // add numbers
// display result in a JOptionPane message dialog
JOptionPane.showMessageDialog( null, "The sum is " + sum,
"Sum Integers", JOptionPane.PLAIN_MESSAGE );
} // end method main
} // end class Addition
then I have made another simple program by window-builder which will perform the four arithmetic operattion between two number. But the result is same for this case. Another picture has added named picture two.
source code for second picture.

it is not appearing correctly in IDE, but when the class file is running in command line, it is appearing correctly.
I have updated my JDK.
what may the cause and solution?
