Objects as parameter inside the method.

[Abishek Kumar]

Can any one give me brief details about passing object as a parameter in the methods.
I am trying to understand the concept from books and online, but would appreciate if any one can give me just brief explanation.

For example:

public void method1(Object1 object1){
...
...
}

What is the concept behind passing object as parameter?

Thanks

Hi Abhishek,

Welcome to Ranch. The benefit/concept behind passing an Object as a parameter are:

Object serves as a container in which you can put many bits and pieces inside. The callers would just need to deal with one single item/argument and NOT many.

You can achieve Pass By Reference.

Does that help?

No you can't. You can pass the value of a reference, but as the link you quoted says, you can't implement pass-by-reference in Java.

Yes. You are right CR . I meant to say, you can achieve and NOT implement.

In a way you pass the object (reference) [Yes indeed it is 'pass by value' ], you can get the 'pass by reference' effects. Otherwise, you can't!
