Using abs () method in java. My compiler doesn't know the method

Question

I have a simple question, but i can't find a solution for it.

I want to use abs() method, but it doesn't work. I'm always getting the error

Cannot find symbol: method abs(int)

I have already tried to use the method by including "import java.math" above the code. But that doens't work too.

Answer 1

Call it as

Math.abs(number)

or import as:

import static java.lang.Math.abs;
