Please help me code the following in: JAVA

Please create the code in as basic way as possible, so I can understand it better :)

Full points will be awarded, thanks in advance!

Program Description Write a program that demonstrates the skills weve learned throughout this quarter. This type of project offers only a few guidelines, allowing you to invest as much time and polish as you want, as long as you meet the program requirements described below. You can write a simple game (e.g., tic-tac-toe, Battleship), a simulation (e.g., a zero-dimensional energy balance model of the climate), or an application (e.g., a mortgage calculator). Your main requirement is that you demonstrate six of the following features in your software program and that you comment and document your code well 1. Functional Decomposition: Use methods (a.k.a., functions) to break up a large program into 2. Looping with Repetition Control Structures: Use two of the following structures: for, while 3. Nested Loops: Use a loop within a loop in your program. Note that this is automatically 4. Branching with Selection Control Structures: Use multiple (i.e., more than one) if/else and/or meaningful chunks, using input to and output from those functions where appropriate do/while, foreach accomplished when using Multi-Dimensional Arrays switch statements in your code. (You dont need to use both kinds of statements. if/else means any kind of if/else statement.) File I/O: Read from or write to a file in your software. Examples of this include be reading in a preset pattern for the computer opponents answers in a game of rock/paper/scissors, or writing a file that logs each move the player makes, effectively recording a history of the game Using Multiple Classes: Build and use more than one class in your project. Note that a class that only has a main method and does not have any instance variables or methods does not count as a class 5. 6.
