Answer 1

Harsh Agrawal
your mistake
* constructors of outer class is inside inner class i.e bro constructors are inside intro class, which made them functions of intro and a normal function requires return type, so you got the error.

To correct this place both constructors of bro outside intro

Harsh Agrawal
simple rule bro

nestes class of four type
1.static nested class
2.non static nested class
3.local class
4.anonymous class.
----------------------------+--+----------------
there are some rule to-->
most important rule
first treated as data member than treated as class.....
----------------------------+--+----------------

where we used neated class.
when one properites has futher properities like

salary
have da,ta,ha

____________________________________________
bro first try to understand the concept then apply

I provide you a rule okk.
for
non static nested class
1.static declaration is not allowed.(non static nested class)
2.you can access anything of outer class.
3.in non static nested class you can only acces the outer class instance data members
and members function...

___________________________________________
i provide you basic rule of your problem

now creates psvm()
and try to solve.
......
happy coding😊

Answer 9

Harsh Aggarwal if you want to create a class within a class you need to inherit it's properties i.e you need to use the keyword extends or implements
eg:
class Cat extends Animal
