 Q1) Write a program to display the Employee(Empid, Empname, Empdesignation, Empsal) information using toString(). [10 marks] 

class Employee

{  

 int Empid,Empsal;

 String Empname,Empdesg;  

 

  Employee(int Empid,String Empname,String Empdesg,int Empsal){  

 this.Empid=Empid;  

 this.Empname=Empname;  

 this.Empdesg=Empdesg;

  this.Empsal=Empsal;

 }  

 public String toString()

{

 return Empid+"\t "+Empname+"\t "+Empdesg+"\t "+Empsal;    

  } 

}  

class Slip6_1

{

public static void main(String args[])

{  

   Employee s1=new Employee(101,"abc","Manager",20000);  

   Employee s2=new Employee(102,"def","Fitter",12000);  

    System.out.println("Roll No   Name Designation Salary");   

   System.out.println(s1);

   System.out.println(s2); 

}  }

Q2) Create an abstract class “order” having members id, description. Create two subclasses “Purchase Order” and “Sales Order” having members customer name and Vendor name respectively. Define methods accept and display in all cases. Create 3 objects each of Purchase Order and Sales Order and accept and display details.
