Question

Write a program to use a class Account with the following specifications:

Class name: Account
Data Members: int acno, float balance
Member Methods:
Account (int a, int b): to initialize acno = a, balance = b
void withdraw(int w): to maintain the balance with withdrawal (balance − w)
void deposit(int d): to maintain the balance with the deposit (balance + d)

Use another class Calculate which inherits from class Account with the following specifications:

Class name: Calculate
Data Members: int r,t ; float si,amt;
Member Methods:
void accept(int x, int y): to initialize r=x,t=y,amt=0
void compute(): to find simple interest and amount
si = (balance*r*t)/100;
a=a+si;
void display(): to print account number, balance, interest and amount.
main() function need not to be used.

Answer 1

public class Account
{
    protected int acno;
    protected float balance;
    
    public Account(int a, int b) {
        acno = a;
        balance = b;
    }
    
    public void withdraw(int w) {
        balance -= w;
    }
    
    public void deposit(int d) {
        balance += d;
    }
}

public class Calculate extends Account
{
    private int r;
    private int t;
    private float si;
    private float amt;
    
    public Calculate(int a, int b) {
        super(a, b);
    }
    
    public void accept(int x, int y) {
        r = x;
        t = y;
        amt = 0;
    }
    
    public void compute() {
        si = (balance * r * t) / 100.0f;
        amt = si + balance;
    }
    
    public void display() {
        System.out.println("Account Number: " + acno);
        System.out.println("Balance: " + balance);
        System.out.println("Interest: " + si);
        System.out.println("Amount: " + amt);
    }
}
