Question
Sketch a class hierarchy of employees from two departments, Sales and Accounts Receivable. Show the attributes (data variables) and functionality (methods/functions/operations) of each. Show an abstract superclass, and place attributes and functionality that is common to both subclasses in this superclass. Override functionality, as is appropriate, in your subclasses.
This assignment requests a class diagram showing 1) encapsulation and 2) inheritance. Make sure you provide enough attributes and functionality to properly model the classes in your hierarchy. (Please Use Lucidchart )
Explanation / Answer
//Sketch for class hierarchy of employees
interface Sales
{
public void setDeptType(int type);
public int getSalesItems();
public void setSalesItems(int Items);
public void purchaseItems(int no);
public int avaliablityItems();
}
interface Accounts
{
public void setDeptType(int type);
public void getTaxAccounts();
public void getNonTaxAccountDetails();
public void getEmpSalaryAccounts();
}
//Department class inherits Sales and Accouns interfaces
class Department implements Sales,Accounts
{
String deptCode;
String deptName;
int soldItemsCount;
int deptType;
int totalItemsCount;
double totalEmpSalary;
public Department(int type)
{

}
public void setDeptType(int type)
{

}
public String getDeptName()
{
if (deptType == 1)
deptName ="Sales";
else

return deptName;
}
public int getSalesItems()
{
return soldItemsCount;
}
public void setSalesItems(int totalItemsCount)
{

}
public void purchaseItems(int no)
{
if(totalItemsCount < no)
System.out.println(" Items are not avaliable... !");
else
totalItemsCount -= no;
soldItemsCount +=no;
}
public void getTaxAccounts()
{

}

{

}
public void getEmpSalaryAccounts()
{

}
}
// Employee Class extneds Department
class Employee extends Department
{
String empId;

{

}
public String getId()
{

public void getEmployeeDetails()
{

}
}
public class HelloWorld{
public static void main(String []args){
Employee obj=new Employee("S001","Kumar",17899,"New Yark","1234567891",1);
obj.getDeptName(); // return Emp Department Name
obj.getEmployeeDetails();
obj.getTaxAccounts(); // It will taxable account deatils
obj.purchaseItems(5); //purchase items list
System.out.println("Total Sold Items " + obj.getSalesItems());
}
