It may not have all of the necessary functionality of the final product.
However, it gives the client a look and feel of what the final product might be like.
This is a relatively cheap way to determine if full-production should go ahead.
A Modular Approach
Rather than writing a Java program which only has a main function, a program can be broken down into a variety of functions which perform specific tasks.
When a function is needed, it is called!
There are some advantages to this approach:
Improved Code Readability and Maintainability By breaking down the code into smaller, manageable modules, each handling a specific part of the functionality, the code becomes easier to read, understand, and maintain.
Enhanced Reusability Modules can often be reused across different parts of the application or even in other projects, saving time and effort by not rewriting code for similar tasks.
Easier Debugging and Testing Isolating specific functionality into modules simplifies identifying and fixing bugs, as each module can be tested independently, allowing issues to be traced more effectively.
Concurrent Development Modular design allows multiple programmers to work on different modules concurrently (at the same time), speeding up development and enabling collaboration on large projects.
Scalability and Flexibility As requirements evolve, modular programs can be expanded or modified by adding, replacing, or updating individual modules without impacting the entire system.
public static void instructions(String[] sheepNames) {
System.out.println("Today's racers are: ");
//loop through the array of Strings and display each String
for(int i = 0; i<.length; i++) {
System.out.println((i+1) + " : " + sheepNames[]);
}
System .out.println("They will race 1000 meters. You will predict the winner. Let's start!");
