Expert Solution & Answer
Chapter 9, Problem 49CRP
Explanation of Solution
Determine the time taken to retrieve a record from the middle of the file:
The total number of records in a file is 50,000 and the time required to interrogate an entry is 5 milliseconds.
- To find the record from the middle of the line, divide 50,000 records by 2 as given below:
- Thus, the number of records from the middle of a line is 25,000.
- To find the time taken to retrieve a record from the middle of a line, multiply 25,000 records by 5 milliseconds as given below:

In this lab, we'll be practicing what we learned about GUIs, and Mouse events. 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

○
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. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.

You must have a main function and a max function. The function int main() will declare an array with the values {12, 100, 10, 1000, 20, 5}. This array will be passed to the max function. The function int max() will perform the necessary operations to find the largest element of the array. After max () is finished, have main () print the largest value and its index in the array.
