Invoking Parent Class Constructor Program:-
class Employee1{
public String name;
public float salary;
public Employee1(String name,float salary){
this.name = name;
this.salary = salary;
}
public void showDetails(){
System.out.println(”Name: ”+name+” Salary: ”+salary);
}
}
public class Manager1 extends Employee1{
public String department;
public Manager1(String department){
super(”Mahmud”,50000F);
this.department = department;
}
public void showDetails(){
super.showDetails();
System.out.println(”Department:”+department);
}
public static void main(String[]args){
Manager1 m = new Manager1(”Engineering”);
m.showDetails();
}
}
