The String.intern() method returns the canonical (or unique) representation of a given string. Once created, this shared representation is cached and any subsequent calls to String.intern() for the same string will return the cached representation. This method is often used when performance is critical as it reduces memory usage by avoiding unnecessary duplicate strings.
