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 0.2095 0.3585 0.1565 0.30The user is supposed to enter the data and press a Calculate button. The program must display the weighted average. Using jGrasp and the Software Development Kit, write a program in response to the following prompt:
