Program To Create Basic Procedural Generation Assignment Solution.

Instructions

Objective

You need to write a java homework that implements basic procedural generation in Java. Procedural generation involves creating algorithms to generate content, such as landscapes or levels, on-the-fly rather than designing them manually. In this assignment, you'll explore how to use Java to generate random terrain or patterns, providing a unique experience each time the program runs. Utilize Java's libraries and control structures to define the rules for generating content dynamically. By accomplishing this task, you'll gain a better understanding of Java programming concepts and enhance your skills in algorithmic thinking and problem-solving, which are crucial in software development.
