Try this: public static double circleArea (double r){ double area = 0; if (r>=0){ area = Math.PI *Math.pow(r , 2.0); } return area; } or this: public static double circleArea (double r){ if (r>=0){ return Math.PI *Math.pow(r , 2.0); } return 0; } Your area variable has scope within the {} brackets which is why you have a problem compiling the return area; which is after the closing }.
