Create class Solution with main method. Implement two static methods - findPriceForGivenBrand and getPhoneIdBasedOnOs in Solution class. findPriceForGivenBrand method: This method will take two input parameters - array of Phone objects and string parameter brand. The method will return the sum of the price attribute from phone objects for the brand passed as parameter. If no phones with the given brand is present in the array of phone objects, then the method should return 0. getPhoneIdBasedOnOs method: This method will take a String parameter os, along with the array of Phone objects. The method will return the phone object, if the input String parameter matches with the os attribute of the phone object and its price attribute ...
