I am working on this Java program and am having issues getting my code to run, but am not getting a compiler error. Where is my mistake?

public class Test {

//Output circle1

System.out.println(" Circle 1 = ");

print(circle1);

//Output circle2

System.out.println(" Circle 2 = ");

print(circle2);

//Output the larger circle

print(" The larger circle is: ");

print(Circle.max(circle1, circle2));

//Rectangle Objects

Rectangle rectangle1 = new Rectangle(3, 5, "blue", true);

Rectangle rectangle2 = new Rectangle(4, 7, "yellow", true);

//Output rectangle1

13.5 (Enable Geometricobject comparable) Modify the Geometricobject class to implement the Comparable interface, and define a static max method in the Geometricobject class for finding the larger of two Geometricobject objects. Draw the UML diagram and implement the new Geometricobject class. Write a test program that uses the max method to find the larger of two circles and the larger of two rectangles
