Question

Q:Write a Java application which allows the user to enter student information

The user will enter full name, address, city, province, postal code, phone number and email in text field controls. The student’s major (Computer Science or Business) will be selected from two radio buttons.
A combo box will display the list of courses for each program whenever the user selects the desired program.
A course will be added to a list box whenever the user selects a course from the corresponding combo box. Make sure that the user cannot add a course several times.
Additional information about the student will be provided from a group of check boxes (such as involvement in various activities, etc).
All the information about the student will be displayed in a text area component. Use simple SWING layout managers, such as FlowLayout, BorderLayout, and GridLayout to create the SWING GUI of this application. Provide the titles for the data that will be displayed in the text area.

Note:I know how to do most of the things from question but i do not know how to implement layouts.
