Which one reveals the error of the code below? public class Foo private Circlecew Circle0: public static void main(String args)method10: public void method10 method20: void method20 uscgetRadins)x System.out printin"What is radius"+cgetRadius0) O c must be declared in method2, since c is private and used in method2. O method1 cannot be called in the main method. O The program compiles fine, but it has a runtime error because the private variable c is null when the println statement is executed. O method2 should be declared before method1, since method2 is invoked from method1 O The program has a compilation error in the printin statement where c may not be defined. A class has an instance variable "int x" and a class variable "static int y". An int variable occupies 4 bytes of memory.
