Hi Naveen, Can you please explain how we are deciding we need to create static or non static, like what is the advantage for creating static, in this video I just came to know that how we have to access the variable and how we can call methods, on which parameter are deciding for static and non static.

Hi Naveen, i am a functional manual tester with 12 years experience. I am studying Java for the first time to lean selenium. Your videos are very easy to understand. Thanks a lot for your time.

Awesome video Naveen. Well explained as always. Here's a question, I got..
Static method surely helps save memory as no object needed to call, isn't it ?? If this is so, can't we use the static method all over the java program?

Quick question.
What is difference between global variable and instance variable? Are both same? Also what is class variable ?

Apne bola static method ko do tarike se call kr skkte hai 1.directly 2.using class name. but jab maine dono tarika use kiya to usme bs "ram" print hua. Int ki value print hi nai ho rhi. usko kaise print kre. Hope you understand my question. Please help me ASAP. thanks in advance.

letters (program what you write) are not visible as in the previous sessions. all previous 8 sessions were clear. Could you please see, if that can be changed.

but sir google said "non-static methods can access any static method and static variable also, without using the object of the class". how???

Hi naveen, i have a question. Can we use the values of static variables in objects of that class.suppose i make 3 oblects and wants to have the value of x which is static and y which is non static...can we call these by 2 by obj.x and simply obj.y.and i value of y would be equally shared in all objects or what?
