ESc101 Laboratory Assignment 
	        	 Thursday of Week of 1/11/04

The assignment consists of two parts A and B. In part A, you have to run the programs 
given and give explanation for the results obtained. In part B you have to write a 
Java Program.

=======
PART A 
=======

1)
	class A
	{
	    private int i,j;
	
		  A(int x, int y)
		  {
			i = x;
			j = y;
		  }
		  A()
		  {
			i = 0;
			j = 0;
		  }
		  void setA(int x, int y)
		  {
			i = x;
			j = y;
		  } 
		  int getAi()
		  {
			return i;
		  }
		  int getAj()
		  {
			return j;
		  }
			
	}


	class B extends A
	{
	    private int total;
	    	
		  B()
		  {
			total = 0;
		  }
		  void setTotal()
		  {
			total = i + j;
		  } 
		  int getTotal()
		  {
			return total;
		  }
	}


	class prog1
	{
		public static void main(String args[])
		{	
			B obj = new B();
			obj.setTotal();
			System.out.println("\n Value of total = " + obj.getTotal());
		}				
	}

------------------------------------------------------------------------------

2)

	class A
	{
	    private int i,j;
	
	    	
		  A(int x, int y)
		  {
			i = x;
			j = y;
		  }
		  A()
		  {
			i = 0;
			j = 0;
		  }
		  void setA(int x, int y)
		  {
			i = x;
			j = y;
		  } 
		  int getAi()
		  {
			return i;
		  }
		  int getAj()
		  {
			return j;
		  }
			
	}


	class B extends A
	{
	    private int total;
	    	
		  B()
		  {
			super();
			total = 0;
		  }
		  B(int x, int y)
		  {
			super(x,y);
			total = 0;

                  }
		  void setTotal()
		  {
			total = getAi() + getAj();
		  } 
		  int getTotal()
		  {
			return total;
		  }
	}


	class prog2
	{
		public static void main(String args[])
		{	
			B obj = new B(10,15);
			obj.setTotal();
			System.out.println("\n Value of total = " + obj.getTotal());
		}				
	}

----------------------------------------------------------------------

3) 
	class superclass
	{
		int i;
	     	
	     void calc(int x)
		 {
			System.out.println("\n The value = " + (x+i));
		 } 
		  
		 int getsuperi()
		 {
			return i;
		 }
		 void setsuperi(int x)
		 {
			i = x;
		 }
			
	}


	class subclass extends superclass
	{
		
	 	  int i;

		  void calc(int x)
		  {
			System.out.println("\n The value = " + (super.i + i + x));	
		  }
		  void calc(float x)
		  {
		  	System.out.println("\n The value = " + (super.i * x + i));
		  } 
		  int geti()
		  {
			return i;
		  }
		  void seti(int x)
		  {
			i = x;			
		  }
	}


	class prog3
	{
		public static void main(String args[])
		{	
			subclass ob = new subclass();
			ob.seti(20);
			ob.setsuperi(35);
			superclass sup_obj = ob;
			sup_obj.calc(10);
			superclass obj2 = new superclass();
			obj2.calc(4);
		}				
	}

--------------------------------------------------------------------

4)

	Add the following statement to the main function in the above program 
        after the last statement. Run the program and justify the outcome.
	                sup_obj.calc((float)4.0);

PART B
=======

Write a program with four classes. Deposit, SimpleInterest, CompoundInterest, and ProgramClass. The 
classes SimpleInterest and CompoundInterest are sub classes of class Deposit.

The class Deposit has DepositNumber, AccountHolder, Amount, RateOfInterest, NumOfYears as member data and a member 
function ComputeInterest.The function ComputeInterest is overridden in classes SimpleInterest and ComputeInterest. 
It calculates the Interest depending on the Interest Calculation Method : Simple Interest or Compound Interest.

In the ProgramClass, write code to take information about 10 Deposits as input from the user 
including information about whether the interest should be calculated as Simple Interest or Compound Interest, 
compute respective objects, and save them in a single array. 

Compute the Interest for each deposit depending on its type using a loop. Then display the Interest calaculated 
for each deposit.
