I created a CircleShape super class, and made circle to inherit CircleShape, then inherited sphere class from circle

Now the user should choose upto 10 objects b/w circle and sphere and find the area.

I used CircleShapeRef to store the objects. Is my syntax correct?

These are the errors I am getting when I executed:
javac testcircle.java


testcircle.java:18: ']' expected
circle CircleShapeRef = new circle();
^
testcircle.java:18: illegal start of expression
circle CircleShapeRef = new circle();
^
testcircle.java:28: ']' expected
sphere CircleShapeRef = new sphere();
^
testcircle.java:28: illegal start of expression
sphere CircleShapeRef = new sphere();
^
4 errors

I think I fixed the problem.....

Yeah, looks like it's just a syntax error, not a logic problem.
