Constructor is used to initialize an object. So each time when you create an object of class you are internally using constructor to create an object. Ex : if the class name is A, then to create object class of this class you will doing as follows... A a = new A(); correct?? Here A() is constructor (Which you wrote after new keyword)

@RahulJha-bu7cv 5 жыл бұрын

I must say its more than enough and not because of 27 classes, its because the way Naveen has explained. With his video tutorial I understood existing framework and already automated few modules of my project in last one month. Received appreciation from customer and they never get to know when I joined my project I was having no knowledge of java and selenium. Big thanks to Naveen. Go for all these videos you will be thankful to Naveen for entire life like me.

I have a question ,since by using this keyword in side the 3rd constructor we are assigning local variables value to global variable Name and age, can we call directly and see there value by using C.name and c.age ?
