Answer 1

I have tried here in Code Playground. It works for me. In order to enter A B C value, you need space. For example: 2.2 3 5

Answer 2

it tells me" java.util.nosuchelementexception"
and "looks like your program needs input
split multiple inputs in separate lines"

Answer 3

I think use import java.util.* and check by using system.out.print

Answer 4

A, B, C are Double but you asking the Console for nextInt two times (B & C)
