E and PI are not functions, they're static fields (data members). That code will output their values correctly. You don't have to import anything, the Math class is in the java.lang package, which is imported by default. (It's the only package imported by default, I believe.)

Java Math Operators and Math Class
A commonly used math operation on variables is to set the variable equal to its own value plus another value. Here is how that looks: ... The second line of this example sets the sum variable equals to its own value (before being assigned the new value) + 20. Which means 10 + 20. Since adding a value to a variable is a very common operation, Java contains a built-in operator for that specific purpose.

You don't have to import anything here. The java.lang.Math class should already be available as java.lang package is imported by default
