Prerequisites: Java Swing
Write a program to build a GUI application which provides the details of the college student, about his course and the fees that need to be paid. The fee is calculated and saved in a text file. The program must also be able to print the receipt.
Approach: The concept is based on the GUI(graphical user interface). The idea is to use Java Swing and AWT. Therefore, we need to define all the methods based on functionality. The methods in the program are as follows:
- Receipt: The prime functionality of this method is to display all the data that is entered in the text fields, the course to be taken and the final amount that needs to be paid. These operations can be done by adding ActionListeners to the button named as receipt.
- Reset: The functionality of this method is to clear the information that is already visible to in the text areas and in the text fields and to add new student’s details and print the fees of that particular student. It can be done by adding ActionListeners to the button.
- Print: The functionality of this method is to print the fee receipt if the printer is available. We can do this by adding ActionListener to the button. The entire information in the text area is named as area2 and is saved in a file in the computer under the name of java.txt. It will also show a dialog box as Data saved successfully.
Below is the implementation of the above approach:

Output:
- When the above program is run:
- When all the details are added in the respective fields:
- When the receipt button is pressed:
- When the data is stored in a text file:
- When print button is clicked, the following options are shown. If the printer is available, then it can be directly printed.
- Preview of the document if the printer is available:
