    Default Not Able to getInstanceOf Object

    Default Not Able to getInstanceOf Object

    Hi guys,

    I am trying identify whether particular object is an instance of the Object,I am using this in the blackberry java application,I am using Eclipse IDE,Even though Object shows it as RenderDetails,But it is not getting under the condition of instanceof Operation,

    com.app.MyObjectDetails@db8a08fa--getting this as Eclipse debugging

    if i check as

    if (Object instanceof MyObjectDetails)
    S.o.p("MyObject")---->i am not getting here


    Any Ideas what could be the problem,?

    Regards
    Rakesh shankar.P

    Your MyObjectDetails class does not override the toString method of Object.

    Could you write a small pgm that compiles and executes to demo the problem?

    Naming a variable with the same name as a java class is confusing: Object.

    Hi,I cannot directly replicate that issue,If I am checking the instanceOf scrollField (OtherFieldwhich is an Object),it is working perfectly.


    ScreenField--It is a sort of Form(basically a manager,Like a JFrame) which is added to some other Manager,which instance is creating a problem.


    class ScreenField extends Manager{

    ScreenField(Manager mgr)
    {
    VerticalfieldManager vfm=new VerticalFieldManager();
    vfm.add(add new LabelField("test");
    this.add(vfm);
    mgr.add(this);
    }



    }
    Since ScreenField contains some other manager,that could be reason of the error?

    Hard to say what the problem is without a SSCCE.
