Java Graphics
(Bonus
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
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. I suggest using the BorderLayout for a panel
containing the buttons, and a GridLayout to hold the drawing panel and button panels.
Regardless of how…

- In a client-server system for a hypothetical banking application, the clients are ATM machines, and the server is the bank server. Suppose the client has two operations: withdraw and deposit. Use the broker architectural pattern to document an initial architecture design for this system: a. Draw a class diagram for this system. Use a client-side proxy to encrypt the data using an encrypt operation and a server-side proxy to decrypt the data. b. Discuss how you plan to apply redundancy tactics on the server. Additionally, identify the quality attribute that this tactic will achieve and discuss any potential side effects of applying it.arrow_forwarda.

Suppose we want greater availability of the server. Discuss what kind of tactics should be used to achieve that.arrow_forwardImplement a C program to find the largest element in a given array. 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. Do not hard code your solution! If we test your code with different array values, we should still get the correct output.
