Mobile Details Management
Create a class Mobile with the below private attributes:
iMEICode – String
isSingleSIM – boolean
processor – String
price – double
manufacturer – String
Write getters and setters as required
Create class Solution (here I used Main) with main method. Implement two static methods –
getCountOfValidIMEIMobiles and findMobileWithMaxPrice in Solution class
getCountOfValidIMEIMobiles:
This method will take array of Mobile objects as input parameter and return the total count of mobiles that has iMEICode with 15 digits and has single SIM provision.
If no mobiles satisfy the given conditions, return 0
findMobileWithMaxPrice:
This method will take an array of Mobile objects, double parameter – discountPercentage, and a String parameter – manufacturerName as inputs.
The method will update price of all mobiles of the given manufacturer name by applying the given discountPercentage. it will return the mobile object of the given manufacturer that has the maximum price after applying discount. This method would return null if the above conditions not satisfy.
Finding newPrice,
newPrice = old price – (old price * discountPercentage)/100;
Note:
1. All String comparisons are case insensitive
2. A mobile has single SIM provision if the attribute isSingleSIM has a true value
3. IMEICode of mobiles can begin with 0. eg: 000008888888999 is a IMEICode with 15 digits.
4. All mobiles provided in the input have unique price.
The above mentioned static methods should be called from the main method.
For getCountOfValidIMEIMobiles, the main method should print the count of mobiles as it is.
For findMobileWithMaxPrice, the main method should print the IMEICode and price of the returned Mobile object. eg; 000008888888999@4421653. If the returned object is null, then it should print “No mobile found”
