What are caching mechanisms?
Caching is a mechanism to improve the performance of any type of application. Technically, caching is the process of storing and accessing data from a cache. A cache is a software or hardware component aimed at storing data so that future requests for the same data can be served faster.
What is basic operation of the cache?
The basic operation of a cache memory is as follows: If the word is found in the cache, it is read from the fast memory. If the word addressed by the CPU is not found in the cache, the main memory is accessed to read the word. A block of words one just accessed is then transferred from main memory to cache memory.

How do you implement a simple cache in Java?

- int capacity;
- public lru(int capacity)
- {
- this.cache = new LinkedHashSet(capacity);
- this.capacity = capacity;

There are three different categories, graded in levels: L1, L2 and L3. L1 cache is generally built into the processor chip and is the smallest in size, ranging from 8KB to 64KB. However, it’s also the fastest type of memory for the CPU to read.
What is LRU in Java?
LRU (or Least Recently Used) is a cache eviction strategy, wherein if the cache size has reached the maximum allocated capacity, the least recently accessed objects in the cache will be evicted.
