Answer 1

There is a thing in java...that...suppose you have a method...of certain class

now u just created an obj. of that class in void main
perfectly fine

now u called obj.method()...it works

now suppose u have inner/sub/nested classes..like the one u hav..
certainly u cant have 2 main methods...
okay
now u cant call a method outside a method...

i mean>>
line 6...b.think() produces no error as it is called in a constructor...(which is by default a method also...)

now line 11....n.cell()..produces error..
because its not in any method or constructor..

just do this...

Brain( ){
n.cell( );
}

//in a constructor...and your code will work

Answer 2

is that the whole sorce code?
