How many Caching mechanisms in java?

[SmallCat1]

I know LruCache and ASimpleCache. anything else??

Unlimited number.
You can implement as many as you want.
I implemented TheCache, ACache, MyCache, YourCache, OurCache, DefaultCache, NonDefaultCache .
I started with nullCache in File NullCache, but a camel refused to compile it. That was my first camel case.
Currently I am refactoring SimpleCache to ComplexCache, but it got so complicated that I fear I will never finish it.

A few popular java caches are Java Caching System by Apache at commons.apache. org/jcs and Ehcache at www.ehcache.org.

JCS, the foundation of JCS is the Composite Cache, which is the pluggable controller for a cache region.

LRU Memory Cache
Indexed Disk Cache
JDBC Disk Cache
TCP Lateral Cache
RMI Remote Cache

Here is the most common list, you can check it out in the Googlee if you want.
