    Moving thread to New To Java, as that's a better home than the JDK sub forum.
    Please do not ask for code as refusal often offends.

    At the end of that code snippet, st refers to a new String "helloworld" and the two other Strings "hello" and "world" are to be destroyed by the garbage collector (if possible).

    kind regards,
