NursingSelection Program

UML Diagram

The NursingSelection program is a Java application designed to simulate the selection process of students for a nursing program based on various academic criteria. It uses a binary tree to evaluate each student's qualifications and a simple scoring system to determine their eligibility.

Program Architecture

Classes and Nested Classes

The program consists of the following classes and nested static classes:

NursingSelection
- This is the main class that contains the main method and other helper methods such as generateRandomName to support the simulation of the student selection process.
Node
- This nested static class represents the nodes of a binary tree, each holding a criterion, a weight, and references to child nodes.
BinaryTree
- Another nested static class which represents the decision-making structure with a root node and a method evaluateGPA to assess student criteria against the tree structure.
Student
- This nested static class encapsulates student data including name, score breakdown, and total score.

Binary Tree Structure

The binary tree is used to model the decision criteria:

The root node checks if a student has all prerequisites.
The left subtree checks science GPA related criteria.
The right subtree checks non-science GPA related criteria.

Each leaf node represents a terminal criterion with an associated weight.

Student Evaluation

The program generates a list of 1000 students with random names and randomly determined criteria. Each student's qualifications are evaluated against the binary tree structure to calculate their total score.

Code Structure

The code is structured as a single Java file with multiple nested classes to represent the program's logic. It uses standard Java libraries and the org.json library to handle JSON operations.

Requirements

The program requires Java 8 or higher to run.
The program requires the org.json library to generate JSON files. (can be included as a Maven or Gradle dependency if you are using a build tool)

Usage

To run the NursingSelection program:

Ensure you have Java installed on your system.
Compile the Java file:
```
javac NursingSelection.java
```
Run the program:
```
java NursingSelection
```
The program will generate a list of 1000 students and display the top 10 students with the highest scores.
The program will also generate two JSON files:
- selected.json contains the list of selected students.
- rejected.json contains the list of rejected students.
- Each JSON file contains the student's name, total score, and score breakdown.
