public abstract class StringInternCache
extends StringCache

A cache for caching often used Strings using String.intern(). The method intern() creates an exact copy of a String object in the heap memory and stores it in the String constant pool. Note that, if another String with the same contents exists in the String constant pool, then a new object won't be created and the new reference will point to the other String. Time complexity of intern() is O(n) where n is the current size of the string pool.
