# Performance Task - Project 1

Create a console-based program to manage student data, such as names, grades, and student IDs. The program will store this data in a List of custom `Student` objects.  Appropriately comment throughout your program and provide test cases to verify that your program works as intended. You are not allowed to use functions for this program.

 

**Tasks**:
1. Create a Student class with attributes:
   - `String name`
   - `int studentID`
   - `float grade`

   Include methods to:
   - Get and set values for each attribute.
   - Display the student's details.

2. Create a StudentManager class with a List to store the `Student` objects.
   - Allow the user to:
     - Add a new student to the List.
     - View all students in the list.
     - Find a student by their ID.
     - Remove a student by their ID.
     - Update a student’s grade.

3. Additional features:
   - Sort students by grade or name.
   - Search for students based on different criteria (e.g., by grade, name, or ID).
   - Implement input validation and handle exceptions for edge cases (e.g., entering invalid data).

Example Features:
- **Add Student**: Input name, ID, and grade, and add the student to the list.
- **Display All Students**: Print out all students’ information.
- **Update Grade**: Update the grade of an existing student by their ID.
- **Remove Student**: Remove a student based on their ID.
