[Introduction] String intern in Java 6,7,8 – String Pool This article will discuss how the String intern method is implemented in Java 6, and what this method does in Java 7 and Java 8 Adjustment. String Pool String Pool (Named String Normalization) This parameter is not of much help in Java 6 because you are still limited to the fixed PermGen memory size. The rest of the discussion will simply ignore the fact that in Java 6 you must set a larger -XX:StringTalbeSize value (compared to the default 1009) if you want to use String.intern() more often - otherwise this method will quickly reduce to 0 (pool size).
