Explanation / Answer

import java.util.*;

class Account
{
private String name;
private String account;
private double accountBalance;
Account()
{
accountBalance=0;
}
Account(String nm,String acc,double accBal)
{
name=nm;
account=acc;
accountBalance=accBal;
}

double showBalance()
{
return accountBalance;
}

boolean debitInfo(double amount)
{
accountBalance=accountBalance-amount;

if(accountBalance<0)
{
return false;
}
else
{
return true;
}

}

void creditInfo(double amount)
{
accountBalance=accountBalance+amount;
}
}

class TestAccount
{
public static void main(String args[])
{
int i;
String nm, acc;
double accBal;
Scanner sc=new Scanner(System.in);
Account act[]=new Account[4];

for(i=0;i<=3;i++)
{
System.out.print("Enter Name : ");
nm=sc.next();
System.out.print("Enter accout number : ");
acc=sc.next();
System.out.print("Enter Balance : ");
accBal=sc.nextDouble();
System.out.println(" ");
act[i]=new Account(nm,acc,accBal);
}

int accountNo;
int choice;
double amount;

while(true)
{
System.out.print(" Which account you wish to process? : ");
accountNo=sc.nextInt();

for(i=0;i<=3;i++)
{
if((accountNo==(i+1)))
{
System.out.print(" Choose your operation : 1. Show Balance 2. Debit 3. Credit 4. Exit ");
choice=sc.nextInt();

switch(choice)
{
case 1:
System.out.println("Your Balance is "+act[i].showBalance());
break;

case 2:
System.out.print("Enter amount : ");
amount=sc.nextDouble();
if(act[i].debitInfo(amount)==true)
{
System.out.println("Your new Balance is "+act[i].showBalance());
}
else
{
System.out.println("Insufficient amount");
}
break;

case 3:
System.out.print("Enter amount : ");
amount=sc.nextDouble();
act[i].creditInfo(amount);
System.out.println("Your new Balance is "+act[i].showBalance());
break;

default:
System.out.println("Thank You!!");
System.exit(0);
}

}
