In which region intern strings are stored?
intern() is an interesting function in java.lang.String object. intern() function eliminates duplicate string objects from the application and has potential to reduce overall memory consumption of your application.. JVM Memory has following regions: Heap region (i.e. Young & Old generation), Metaspace and others regions. In this video let's learn through practical examples, in which region, the intern string pool is stored.
