Question

Using jGrasp and the Software Development Kit, write a program in response to the following prompt:

Design a GUI program to find the weighted average of four test scores. The four test scores and their respective weights are given in the following format:

testscore1 weight1
...

For example, the sample data is as follows:

75 0.20
95 0.35
85 0.15
65 0.30

The user is supposed to enter the data and press a Calculate button. The program must display the weighted average.

Remember to follow proper form and design in your response.
