    Default Hi , need clarification on how to get the object from one class to another class

    Hi iam a new user,

    Right now im working in selenium and i have knowledge on java basic programming and little bit
    about oops.Here is my question

    1. I have a class "SeleniumCore" , from class B i have inherited the object and the actions are successfully performed.

    2. My folder structure is like

    SeleniumCore - >ClassB (Action performed) ->Class C ->Class D

    From class D i want to invoke the SeleniumCore object.
    when i invoke and run at class D the object shows the null value and which means that not able to take the
    initial object value.

    Kindly help me to understand the oops concept here

    Thanks,
    Sha

    An object can be passed to another class through a constructor of the second class:

    ClassA classA = new ClassA();
    ClassB classB = new ClassB( classA );

    classB has the object classA to do with as it pleases.

    Another way is to use setters:

    ClassA classA = new ClassA();
    ClassB classB = new ClassB();
    classB.setClassA( classA );

    Hope this helps.

    In ClassD you can created object of SeleniumCore class's object. In following code I have created object of class SeleniumCore in class ClassD and printed it ,
