Java input problem

Question

I will create a simple program that converts inch to cm.
It gets user data in double and multiplied it by 2.54 and stores it to a variable.

But the problem is when I use Scanner and multiple it by 2.54 it says that you can not store a scanner value into a double!

My question is when should I must use .nextDouble or is there a short way to convert sccaner to double?

Ps: I read this program in js with no problem.

Answer 1

Scanner sc = new Scanner(System.in);
double cm = sc.nextDouble();

This is how you get input, wonder how you got problems.
