What Is Constructor In Java And Constructor Overloading With Real Time Examples

[@reshmap7520]

Hello Mukesh, Another excellent lesson. You are class apart on KZbin. You make it so easy to understand the concept. Cant thank you enough🙏

[@Mukeshotwani]

Hi Reshma, thank you so much for such a nice comment. It made my day. Keep learning.

[@afsalsb7876]

Ohh my god, no video better than this in youtube about constructor,शाबाश

[@Mukeshotwani]

Thanks Afsal bhai..

[@sourabhyadav596]

Whole series is really helpful for me... great work

Hey Mukesh, thanks for the tutorial! Could you please clarify the following? rest all are clear.. 1. @1:45, can you explain with example why constructors cannot be synchronized and what happens if we try to make them as such? 2. @17:46, why did you write result = marks; and not this.result = marks; as result being a non static variable. Is it because the rule to write non static variables directly in non static methods also apply for constructors?

[@Mukeshotwani]

HI Imran, I really appriciate your dedication for learning, for first point The JVM ensures that only one thread can invoke a constructor call at a given point in time. That is why no need to declare a constructor as synchronized and it is illegal in Java. Second point- Video coming for this on Wednesday. Quick point- if global variable and local variable have different name then no need of this keyword.

Hi Mukesh, thanks for this video. clear explanation of the concept. Please also upload list of frequently asked java programs.

Yes will try my best Rashmi

Hello Sir, I got confused with scenarios like the default constructor creates when we create the object then what is need of creating the constructor as separate ???

[@tapaskhandai]

Hi Mukesh, Could you please make a video on the constructor role in POM. How it works? Why we need to create a constructor in every page? What will happen if we dont create constructor?

[@pranalilanjewar4293]

Hi Mukesh, Thanks for the above video, I understand the Constructor concept but i have question here , when we have to use this constructor in real scenario?

[@Mukeshotwani]

Hi Pranali, First link of Selenium itself we can implement this. Example WebDriver Driver=new ChromeDriver() DesiredCapabilities caps = new DesiredCapabilities(); caps.setHeadless(true); WebDriver driver = new ChromeDriver(caps)

[@ankitshrivastava1772]

Hi, Mukesh can we create any method inside the constructor?

[@Mukeshotwani]

Nopes, you can call method from cons and you can also another cons from same class (using this) and base class cons using super.

[@hamzaahmed6131]

Hi Mukesh thanks for a clear explanation of constructor, can you please make another video on copy constructor concept as well

[@Mukeshotwani]

Sure Ahmed will make soon on this, but we dont use copy constructor in real time in Selenium

[@atulthorat5670]

Thank you Mukesh!

[@Mukeshotwani]

Thanks Atul, Now a days seems you are not watching youtube 😂

[@divyangjani7600]

sir one thing is copy constructor.. can you explain what is it?

[@Mukeshotwani]

Hi Divyang copy constructor accept an object of the current class and initialize the values of instance variables with the values in the obtained object public Student(Student std){ this.name = std.name; this.age = std.age; }

[@9745754904]

Wats the use of counstructor

[@Mukeshotwani]

watch the video till end,I have explained by taking Selenium example

[@9745754904]

@@Mukeshotwani yes mukesh, my doubt was if setheadless is implemented in a function rather that in a constructor , and if we acess that by creating object, then there is any use of constructor.sorry if I. Asked any silly, just clarify all. Doubts

[@Mukeshotwani]

Hi Jino setHeadlessMethod is part of ChromeOption class and ChromeDriver has one constructor which accepts ChromeOption object as parameter

[@theRandom_Guy151]

Why does a constructor name is always the same as class name. Why cant we use a different name?

[@Mukeshotwani]

Hi Dipankar if you use other name it will become method
