    Default nullify object

    Is there any way I can nullify an object after having created it in a more generic sense rather than specifying its specific name.

    e.g. 'object one = new object()' can be nullified by 'one = null',
    instead of this I want something along the lines of 'this = null' in the constructor or introduce some break in the constructor to stop an object being created if a criteria is not met.

    How can I go about doing this?

    I understand your advice though can't work me as I use an environment called bluej, where objects are created outside the program code so I can't really force the user to try use a try and catch when they simple create an instance of a class. Thank you for trying.

    There are many examples in the Java SE. See the URL class for example.
