I think you're calling the constructor like s[i].Student() which is incorrect.

Java will assume that Student() is a method and not a constructor. Since you don't have a method normal Student() method in your class, for sure, it will not be found.

Remember, constructor is not just a plain method. It's a special method to instantiate objects.

Also you don't need a class Main, take your method main and put it inside your class Student, remove this line:

s[i].Student();

And the program runs fine

You just don't need that line: s[i].Student();

The Student() constructor is called when you write new Student().

Read this about constructors in Java.

On line 35 you are correctly instantiating a class with the constructor, 

s[i]=new Student();

On line 36 you're incorrectly (and for no apparent logical reason?) calling a constructor like a method. Remove this line:

s[i].Student();
