FindProjector.java

/*
--------------------------------------------------------------------------------
Create a class Projector with below attributes:

    projectorId   - int
    projectorName - String
    price         - int (per unit)
    rating        - int
    availableIn   - String (Amazon, Flipkart, TataCliq)

- The above attributes should be private.
- Write getters, setters and parameterized constructor as required.

--------------------------------------------------------------------------------
Create class Solution with main method.

Implement one static method - findMaximumPriceByRating in Solution class.

findMaximumPriceByRating method:
    - The method will return the maximum priced Projector object from array of Projector objects
      whichever has rating greater than the given rating and which is available in TataCliq.
    - If no Projector with the above conditions is present in the array of Projector objects,
      then the method should return null.
    - Note : No two Projector will have the same price.
    - All the searches should be case insensitive.

--------------------------------------------------------------------------------
The above mentioned static method should be called from the main method.

For findMaximumPriceByRating method:
    - The main method should print the projectorId from returned object if the returned value is not null
      else it should print "No such Projector".
      Eg: 1001
      where 1001 is the projectorId which has the maximum price.

--------------------------------------------------------------------------------
Before calling these static methods in main, use Scanner object to read the values of four Projector objects
referring attributes in the above mentioned attribute sequence.

Next, read the value of one int parameter for capturing rating value.

--------------------------------------------------------------------------------
Consider below sample input and output:

Sample Testcase 1:

1001
