Chapter 3, Problem 4PP
Program Plan Intro
To calculate the percentage of student's score and displayround-off the value and display the value up to 5 decimals.
Program Description:
Starting with the main method, the following steps are taken −
- Variables − marksGot, totalMarks and prcnt are declared of float type.
- Obtained marks and total marks are inputted through user.
- Percentage is calculated and stored in the variable prcnt.
- Rounded-off value of prcntto the nearest whole number is displayed using ceil function.
- Precise value up to 5 decimals of prcnt is displayed using setprecision function.

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose.
