Question 2: Given the list of employees, count number of employees with age 25?

Answer:
You can use combination of filter and count to find this.

List<Employee> employeeList = createEmployeeList();
long count = employeeList.stream()
.filter(e->e.getAge()>25)
.count();

System.out.println("Number of employees with age 25 are : "+count);
