I must write a interface to enter course information for transfer students. The created data file should be sequential in nature, with the student's name, his/her ID number, the course number from the previous college, and the accepted course number at the current college. The code I wrote so far is as follows:

I am battleling to insert spaces where the people can insert information and also for the last line "Local Course Number:" to show on the application.

Please tell me what I am doing wrong.

Edited 7 Years Ago by ~s.o.s~: Added code tags, please learn to use them.

I can't see where you add your fields to secondRow.
One small point: when you catch an IOException you just exit. This will leave you with no information about what went wrong or where. You should do a printStackTrace for the exception before exiting so you know what happened.

I included the secondRow information, however it's still not working.

Please help. I need to send my assignment in and I am really battleling. My assignment needs to be in by Monday..

Edited 3 Years Ago by mike_2000_17: Fixed formatting

1. "still not working" tells us nothing. You MUST explain exactly what errors you get, or in what way the result differs from the expected result.
2. Post your code with tags so we can read it.[code=java] tags so we can read it.

I am not receiving any errors when compiling, however when I "Run Java Application" it runs but its not showing the way it should. The Name, Student ID, Transfer Course Number and Local Course Number must show under each other and there must be spaces for the people to insert text. I tried everything I know but I cannot see where I made a mistake. Please help.....

As JamesCherrill said, we will not read your code the way you posted it. Use code tags. When you create a new post click the code button and put your code between the tags

Here is the code that I am battleling with. Please help me...

Once again:
Your code is huge, we are not your teacher to read the whole thing.
1) What errors do you get?
2) At which line?
3) What does it do, and what it is supposed to do?

As mentioned previously. The program run successfully, however it is not showing as it's suppose to show. The Name, Student ID, Transfer Course Number and Local Course Number must show under each other and there must be spaces for the people to insert text. I tried everything I know but I cannot see where I made a mistake. Please help.....

After running the code, I noticed that you declared the JTextFileds but you didn't add them to any JPanel

//Add fields to rows
		firstRow.add(nameLabel);
		secondRow.add(studentIDLabel);
		secondRow.add(transfercourseNumberLabel);
		secondRow.add(localcourseNumberLabel);

		//Add rows to panel
		fieldPanel.add(firstRow);
		fieldPanel.add(secondRow);

You add the labels but I didn't see any code the does the same for:

JTextField name = new JTextField(35);
	JTextField studentID = new JTextField(40);
		JTextField transfercourseNumber = new JTextField(40);
		JTextField localcourseNumber = new JTextField(45);
