Custom Query Methods

Suppose you have an Employee entity with one Age field. Which of the following custom query methods will you use to find all the employees who are younger than the specified age?

Hint:

• Think of the naming convention for custom methods that you were taught in this module.
• Let's say there is no field with the attribute name 'X' in the Employee class. Then, is the method's declaration findByX valid?

1) List findEmployeesYoungerThan(int age) 

2) List findByAgeLessThan(int age) 

3) Employee findByAgeLessThan(int age) 

4) List findAgeLessThan(int age) Provide right solution
