Analyze the following code: public class A { private int x; public static void main(String[] args) { int y; System.out.println(x); } } The program has a compilation error since 'x' is non-static and therefore cannot be referenced in the main method. The program compiles and runs fine. The program has a compilation error since variable 'y' is not initialized and therefore causes errors. The program has a compilation error since variable 'x is private and therefore cannot be accessed in the main method
