Given the following Area class, how would I call the calcAreaSquare method in AreaTest. java with square with side length of 6? public class Area { ... public static double calcAreaSquare(double x) { return x * x; } }

You can call the static method using the following statement:

double area = Area.calcAreaSquare(3.5);

Explanation:

In  Java, a static method can be called by directly using the Area class name and followed with a dot syntax as shown above. This will invoke the calcAreaSquare() method and act on the input 3.5 and return the output to the variable area.  

Calling a static method doesn't need to go through a class instance.
