tcs ira 29November 2021 java coding question solution.

 Question:

Create the class Bank with below Attributes.

bankId-int

bankName-String

numberOfCustomers-int

city-String 

write parametrized constructor as well in Bank Class.

Create class Solution  with main method.

Implement 2 Static methods-findAvgNumberOfCustomersByCity and 

getSecondLowestNumberOfCustomersBank in Solution class.

findAvgNumberOfCustomersByCity method-This method will take two input

parameters.Array of Bank Objects and String Parameter city and will return

the average number of customers of bank from array of Bank Objects for the 

given city.

   If no banks with given city present inside the array of the Bank Objects,

then the method should return 0.

The main method should print the average of the number of Customers if the 

returned value is greater than 0.Else main method will print "Bank not Found".

getSecondLowestNumberOfCustomersBank method- This method will take 1 input 

Parameter that is Array of Bank Objects and return Bank Object having the 

second lowest Number of Customers among the Bank Objects only if the number

Of Customers in that Bank is an even number.

   If no bank with above condition is present in the array of Bank Objects,

 then the method should return null.

   The main method should print bankId,bankName,numberOfCustomers and city

from the returned bank Object if the returned value is not null.

else the main method method will print "Bank not Found".
