I have an doubt In c++ we cant initialize the variables present in class, so we use constructors In java since we write each and every line inside a class, we can directly write int a =5; in this case we dont need constructor rght, so why should we use constructor in java?

[@SimpleSnippets]

So instead of me answering this one, I request you to try it out yourself. create a simple java class and in that class create a data member lets say x and give it a value x = 5 in the class itself without declaring a constructor. Now in the main function when you create an object, try to change that variable value of 5 to something else. See if it allows. It wont. Try the same program but this time assign value to the data member from the constructor and then later try to change it, I am sure it will allow you to change that. Thats the difference. 😇

We can't take user input in parameterized constructor ?

[@roopagaur8834]

Nice explanation. Kindly clear my doubt ,see one class one simple method with parameter in a program. For this i ll create object of class and i ll call that method, default constructor does intialization , then why to use parameterized constructor

[@roopagaur8834]

Also in simple manner also i can assign value int a= 5 and i can use sop(..) then why to separately use constructor for that, I understand your video types and all, but not the exact purpose kindly reply
