Write A Java Programme That Will Be Used As A School Finance System

Write a Java programme that will be used as a school finance system. Write a program to print the area of a rectangle by creating a class named 'Area' having two methods. The first method named as 'setDim' takes length and breadth of rectangle as parameters, and the second method named as 'getArea' returns the area of the rectangle. Length and breadth of rectangle are entered through the keyboard. Write a program that would print the information (name, year of joining, salary, address) of three employees by creating a class named 'Employee'. The output should be as follows: Name Year of joining Address Robert C- WallsStreat Sam D- WallsStreat John B- WallsStreat

Write A Java Programme That Will Be Used As A School Finance System

This paper presents a comprehensive Java implementation for a school finance system, integrating multiple functionalities such as calculating the area of a rectangle and displaying employee information. The objective is to demonstrate object-oriented programming principles through well-structured classes, user input handling, and formatted output. The solution encompasses three core tasks: creating a class to compute the area of a rectangle, developing an employee information display, and constructing a school finance system foundation.

Introduction

Java programming provides robust features for building diverse applications, including financial and administrative systems for educational institutions. In this context, designing modular and reusable classes enhances maintainability and scalability. The tasks outlined include implementing a rectangle area calculator and an employee information system, each serving to practice class design, method implementation, and user interaction in Java.

Task 1: Calculating the Area of a Rectangle

The first task involves creating a class named 'Area' with two methods. The setDim method accepts length and breadth of the rectangle as parameters and sets these dimensions within the class. The getArea method calculates and returns the area based on the stored dimensions. User input is obtained via the keyboard through a Scanner object, and the resulting area is displayed on the console.

Implementation:

public class Area {


private double length;


private double breadth;


public void setDim(double length, double breadth) {


this.length = length;


this.breadth = breadth;


}


public double getArea() {


return length * breadth;


}


}


public class RectangleAreaCalculator {


public static void main(String[] args) {


Scanner scanner = new Scanner(System.in);


Area rectangle = new Area();


System.out.print("Enter length of the rectangle: ");


double length = scanner.nextDouble();


System.out.print("Enter breadth of the rectangle: ");


double breadth = scanner.nextDouble();


rectangle.setDim(length, breadth);


System.out.println("The area of the rectangle is: " + rectangle.getArea());


scanner.close();


}


}

Task 2: Displaying Employee Information

The second task is to create an Employee class with attributes for name, year of joining, salary, and address. Instantiate three objects of this class with the specified information and print their details in a formatted manner. This demonstrates object instantiation, attribute assignment, and output formatting in Java.

Implementation:

public class Employee {


String name;


int yearOfJoining;


double salary;


String address;


public Employee(String name, int yearOfJoining, double salary, String address) {


this.name = name;


this.yearOfJoining = yearOfJoining;


this.salary = salary;


this.address = address;


}


}


public class EmployeeInfoDisplay {


public static void main(String[] args) {


Employee emp1 = new Employee("Robert", 2015, 50000, "WallsStreat");


Employee emp2 = new Employee("Sam", 2016, 55000, "WallsStreat");


Employee emp3 = new Employee("John", 2017, 60000, "WallsStreat");


System.out.printf("%-10s %-15s %-10s %s%n", "Name", "Year of Joining", "Salary", "Address");


System.out.printf("%-10s %-15d %-10.2f %s%n", emp1.name, emp1.yearOfJoining, emp1.salary, emp1.address);


System.out.printf("%-10s %-15d %-10.2f %s%n", emp2.name, emp2.yearOfJoining, emp2.salary, emp2.address);


System.out.printf("%-10s %-15d %-10.2f %s%n", emp3.name, emp3.yearOfJoining, emp3.salary, emp3.address);


}


}

Task 3: School Finance System Skeleton

While the assignment mentions creating a school finance system, explicit functionalities are not detailed beyond the previous tasks. A foundational approach involves designing core classes such as SchoolFinance with methods for managing financial data, adding student or staff records, and generating reports. Given the scope, a simple placeholder class can illustrate how such a system might start, emphasizing extensibility and object-oriented design principles.

public class SchoolFinance {


// Placeholder for future implementation of financial management features


public void addTransaction(String description, double amount) {


// Logic to add a financial transaction


}


public void generateReport() {


// Logic to generate financial report


}


}

Conclusion

Implementing modular classes such as Area and Employee promotes code reusability, clarity, and ease of maintenance. The integration of user input handling and formatted output demonstrates effective Java programming practices. Extending this foundation towards a complete school finance system would involve developing additional classes, interfaces, and data management functionalities, catering to the specific financial operations required by educational institutions.
