Multithreading Practice Task 1

Readers-Writers

Create class Storage, which contains array with 10 000 000 integers. Class should contain two methods:

• Calculate sum of integers
• Generate and fill array with new 10 000 000 integers

Create class Reader, that should calculate sum of integers of the Storage and print it once in 0-3 seconds.

Create class Writer, that fill Storage with new integers once in 0-5 seconds.

Create 4 Readers that simultaneously prints sum.

Create 2 Writers that simultaneously fill Storage with new integers.

There should be following restrictions:

• 0-4 readers and 0 writers can work with storage at the one moment of time (all writers should wait until readers will finish work)
• 0 readers and the only 1 writer can work with storage at the one moment of time (all readers and other writers should wait until this writer will finish work)
