Describe String intern() methodology

As indicated by Oracle records, when the intern methodology is summoned, if the String steady pool as of now contains a string equivalent to the String object as controlled by the equals(Object) technique, at that point the string from the pool is returned. Generally, the String object is added to the pool and a reference to the String object is returned. The errand of intern() technique is to put String (that is passed to the intern methodology) into the string steady pool.
