@dhrutisundarbiswal5150 6 месяцев назад

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 ?

Hi Naveen the 27 java classes by you are enough for selenium to work in real time also?? Pls respond

@RahulJha-bu7cv 5 лет назад

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.

Hi what is the use of constructors ? and why do we use them in JAVA and Selenium ? I understood the concept and wrote the notes and executed the code Thanks In Advance

@SiddharthTheRock 6 лет назад

I am also having same query.

@sharankonka7701 5 лет назад

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)

Hi Naveen, don't think you even need to say "If you like my video" at the and I guess its by default that everyone loves your teaching lol. My two cents.
