 Q1) Design a class for Bank. Bank Class should support following operations; a. Deposit a certain amount into an account b. Withdraw a certain amount from an account c. Return a Balance value specifying the amount with details [10 marks] 

import java.io.*;

class Bank

{

    int acno;

    String name;

    double balance; 

    

    public Bank(int ano,String n,double b)

    {

        acno=ano;

name=n;

balance=b;

    }

    

   public void viewBalance()

   {

System.out.println("Account Number : " +acno ); 

       System.out.println("Name: " + name);     

       System.out.println("The balance is: " + balance); 

   }

  

   public void deposit(double amount)

   {

       balance += amount; 

   }

   

   public void withdraw(double amount)

   {

balance-=amount;

   }   

}

class Slip7_1

{

public static void main(String args[]) throws IOException

{

Bank s=new Bank(1,"abc",500);

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

int ch;

do

{

System.out.println("Enter \n1.View Balance\n2.Withdraw\n3.Deposit\n4.Exit");

ch=Integer.parseInt(br.readLine());

   switch(ch)

   {

case 1:s.viewBalance();break;

case 2:System.out.println("Enter Amount to Withdraw");

double amt=Double.parseDouble(br.readLine());

s.withdraw(amt);

break;

case 3:System.out.println("Enter Amount to Deposit");

double amt1=Double.parseDouble(br.readLine());

s.deposit(amt1);

break;

    }

}while(ch!=4);

}

}


 Q2) Write a program to accept a text file from user and display the contents of a file in reverse order and change its case.

// Demonstrate FileReader.

import java.io.*;

class ReverseFile

{

public static void main(String args[]) throws Exception 

{

FileReader fr = new FileReader("Sample.txt");

BufferedReader br = new BufferedReader(fr);

String s,s1="";

while((s = br.readLine()) != null) 

{

s1+=s+"\n";

}

System.out.println("********File content in reverse order********");

StringBuffer sb=new StringBuffer(s1);

System.out.println(sb.reverse());

System.out.println("********File content in Upper case********");

System.out.println(s1.toUpperCase());

fr.close();

}

}
