Typing some code and debugging it until it works will not be a best way to write a program.
Hence, the given statement is “False”.
Expert Solution & Answer
Explanation of Solution
Developing a program:
There are many steps to develop the program. It includes Analyze the program, Determine specification, Creating a Design, Implement the Design, Test/ Debug the Program and Maintain the Program.
Steps in software development process:
Analyze the program:
In this phase, the problem is analyzed clearly and figure out what the problem should solve. It requires the clear understating of the problem and the further analysis is made until the programmer really knows what the problem is.
Determine specification:
After analysis, it is responsible for the programmer to decide what will be the inputs and outputs of the program and how they should decide the factor, that how they relate to each other.
Creating a Design:
In this phase, the overall structure of the program is formulated. The main task in this phase is to design the
Implement the Design:
In this phase, the created design is translated into a computer language and put it is into the computer. The implemented algorithm can be translated into
Test/ Debug the Program:
In the phase, the developed program is tested and checks whether it runs properly without any error. The errors are often called as bugs in such cases, it should be tested and fix them. This process of locating and fixing errors is called debugging a program.
Maintain the Program:
In this phase, the program is continued to develop in response to the needs of the users. Most of the programs are never finished for such case it keeps evolving over years of use.

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…
