        for(int i=0; i<Emp.size();i++)
        {   
            Employee e = (Employee)Emp.get(i);
            System.out.println(e);
            
        }
        Emp.forEach(i -> System.out.println(Emp));
        
        for(Employee i : Emp)
        {
            System.out.println(Emp);
        }
        
        
    }
    }

Answer 1

emp.add(e1); etc is missing

you have created the employee objects, but you did not add them to the list. thus the list is blank, and not printing anything

Answer 2

add Employee in your ArrayList.

     ArrayList<Employee> Emp = new ArrayList<>();
        Employee e1 = new Employee(101, "Ravi", "Delhi", "2000");
        Employee e2 = new Employee(102, "Vineet", "Mangalore", "5000");
        Employee e3 = new Employee(103, "Punit", "Mumbai", "3000");
        Employee e4 = new Employee(104, "Shruti", "Banglore", "6000");
        Employee e5 = new Employee(105, "Ritu", "Hyderabad", "8000");
        Emp.add(e1);
        Emp.add(e2);
        Emp.add(e3);
        Emp.add(e4);
        Emp.add(e5);

hope , it will resolve your issue.

Answer 3

This is because your ArrayList Emp is empty. You have created the Employee object but you have not added it to Emp. add it to Emp like Emp.add(e1).
