Q) Develop a java application that creates one account and performs the fallowing operations ?



1)      balance enquiry
2)      deposit
3)      withdraw
4)      view details
A)
Account
accno
name
balance
type
getbalance()
Deposit()
Withdraw()
Viewaccountdetails()
Account is class name
accno , name , balance , type are Properties(general terminology) / attributes (UML terminology)  /  instance variables (java terminology)
Instance methods (java terminology) / operations (UML terminology)   /behavior

// save as ExecuteAccount.java

//Execute account
class account {
       int accno;
       String name;
       float balance;
       String type;
       void storeaccountdetails()
       {
              accno=1001;
              name="krishna";
              balance=8000;
              type="savings";
       }
       float getbalance()
       {
       return balance;
       }
       void viewaccountdetails()
       {
              System.out.println("account :"+accno);
              System.out.println("A/c holder name :"+name);
              System.out.println("Balance (Rs) :"+balance);
              System.out.println("A/c type :"+type);
       }
       void deposit(float amt)
       {
              balance = balance+amt;
       }
       void withdraw(float amt)
       {
              if(balance>amt)
              {
                     balance= balance-amt;
                     System.out.println("please collect Rs :"+amt);
              }
              else
                     System.out.println("can't withdraw. Insufficient funds");
       }
}

class ExecuteAccount
{
       public static void main(String[] args) {
       account acc= new account();
       acc.storeaccountdetails();
       acc.viewaccountdetails();
       acc.deposit(40000);
       acc.withdraw(15000);
       float bal = acc.getbalance();
       System.out.println("A/c balance is (Rs) :"+bal);
       acc.withdraw(12000);

       }

}

Output :
account :1001
A/c holder name :krishna
Balance (Rs) :8000.0
A/c type :savings
please collect Rs :15000.0
A/c balance is (Rs) :33000.0
please collect Rs :12000.0

Q) Explain about nested classes?

A) ->defining a class with in another class is known as nesting of the class. Ex: class A {        class B        {                      } //nested class, and inner class.because it is not static class. } //enclosing class or outer class. ->static class is declared in inside an another class then it does not become an inner class. Note: non-static nested class is known as “inner class”. In the above example class B is nested but not an inner class. Ex: class D {        static c        {                      } //nested class, but not an inner class , because of static class. } //outer class. ->we have three different kinds of inner classes. 1) Member inner class 2) Meth...
