Answer:
1. More access to data
2.convenience
3. Easy creation of BI solutions
4. Report creation
5. Saves time
Explanation:
A data warehouse can be described to be an electronic storage system that contains large amount of facts and information which sources for and also maintains data from different sources; either external or internal.
The most important reason for a data warehouse is for it to store great amounts of data to be used for query and also to be used for analysis.
Why do we use a data warehouse?
1. Users have more access to data due to the integration of various sources of data. It makes use of real time data facts
2. You can conveniently store and also create metadata
3. Business intelligence solutions can easily be created using data warehouses.
4. Users can easily create their own reports
5. Data warehouses makes accessing different data sets faster. It is a time saver as business users are not going to spend time trying to retrieve data from various sources.
Answer:
Attached are screenshots of the working code - baring in mind this only works on mutable Collection types. (ones that can be changed) if you use Collections that don't support this you may experience an Unsupported Operation Exception - but this is expected.

Using Java streams as an alternative for some answers.
Answer:
An algorithm is a specific procedure for solving a well-defined computational problem. ... It requires an understanding of the alternatives available for solving a computational problem, including the hardware, networking, programming language, and performance constraints that accompany any particular solution.
Answer: False
Explanation: Functional requirement is the requirement in the operating system that gives the description of the functioning and specific action that is done by system.
Thus, receiving the data rapidly is not the form of functional requirement as it does not specifies any function that is to be done and receiving of data is already being done and at faster rate in future.
Performance requirement is the factor that is required for defining that how well a system should perform the function.So, reviving data at rapid rate is performance requirement.So, the statement given is false.
