What is the result of compiling and running the following code?public class Tester{static int x = 4;int y = 9; public Tester(){System.out.print(this.x); // line 1printVariables();}public static void printVariables(){System.out.print(x); // line 2System.out.print(y); // line 3}public static void main(String... args) { // line 4new Tester();}}

Compile error at line 2 (must access x by writing Tester.x)

Compile error at line 1 (static x must be only accessed inside static methods)

Compile error at line 4 (invalid argument type for method main)

Compile error at line 3 (static methods can't make reference to non-static variables)

Declaration and Access Control
Suppose a class has public visibility. In this class we define a protected method. Which of the following statements is correct?

This method is accessible from within the class itself and from within all classes defined in the same package as the class itself.

This method is only accessible from inside the class itself and from inside all subclasses.

From within protected methods you do not have access to public methods.

In a class, you cannot declare methods with a lower visibility than the visibility of the class in which it is defined.
