Answer 1

If you do not remove it then it will be a local variable and it's scope will be limited to the constructor block.

But if you remove int then the instance variable x which is declared outside the constructor will be modified.

Answer 2

Because x is an instance variable and they have default values, it is 0 for int type.

Edit: To get 5 as output, kindly remove the "int" inside both constructors.
c=5; & x=c;
