Memory Sequence Game - Java Program for Console Based Game

This program represents the Memory-Sequence game where the player can choose a particular difficulty and play the game accordingly. In this game random sequences of numbers are presented to the player and then the screen is wiped clean. Finally, the player is asked to repeat the sequence exactly as it was displayed to him. In the steps to develop this console based application I had to face a handful of problems. However, solving these problems helped me to learn some necessities about Java programming and game designing concepts.

Program Reflection
This program represents the Memory-Sequence game where the player can choose a
particular difficulty and play the game accordingly. In this game random sequences of numbers
are presented to the player and then the screen is wiped clean. Finally, the player is asked to
repeat the sequence exactly as it was displayed to him. In this way, the length of the sequence is
increased from 3 to 15. Once the user succeeds to answer all 15 questions, the new Highest score
is set and a Congratulation message is displayed.
In the steps to develop this console based application I had to face a handful of problems.
However, solving these problems helped me to learn some necessities about Java programming
and game designing concepts. One very remarkable problem that I had to face was in the
execution of the Screen Clear statement. The following command new ProcessBuilder("cmd",
"/c", "cls").inheritIO().start().waitFor(); was producing run-time errors when the program was
being executed using the Eclipse IDE. Therefore, I did a bit of research and realized that the
Eclipse console does not allow commands to clear its console memory buffer and hence this
command was invalid there. Finally, I had to re-execute this code using BlueJ and the expected
output was produced. The program is also executing perfectly in the Windows Console
environment.
