Question

Analyze the following code. Public class Test {int x; public Test(string t) {System.out.println ("Test");} public static void main(String[] args) {Test test = null; System.out.println (test x);}} A. The program has a compile error because test is not initialized. B. The program has a compile error because x has not been initialized. C. The program has a compile error because you cannot create an object from the class that defines the object. D. The program has a compile error because Test does not have a default constructor. E. The program has a runtime NullPointerException because test is null while executing test x. Analyze the following code. public class Test {public static void main(String[] args) {double radius; final double PI = 3.15169; double area = radius "radius" PI; System.out.println("Area is" + area);}} A. The program has compile errors because the variable radius is not initialized. B. The program has a compile error because a constant PI is defined inside a method. C. The program has no compile errors but will get a runtime error because radius is not initialized. D. The program compiles and runs fine.
