Optimal page replacement algorithm in java software#

Write a JAVA program to simulate producer-consumer problem using. LRU Page Replacement Algorithm in OS The page that has not been used for the. The Optimal Page Replacement Algorithm cannot be implemented in a general purpose operating system because it is impossible to compute reliably how long it will be before a page is going to be used, except when all software that will run on a system is either known beforehand and is amenable to static analysis of its memory reference patterns. Reference = Integer.parseInt(br. Write a JAVA program to simulate page replacement algorithms. Ref_len = Integer.parseInt(br.readLine()) ("Please enter the length of the Reference string: ") Supports FIFO, LRU, and OPTIMAL algorithms. page-replacement-algorithm,implementations of FIFO and LRU algorithms.
