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 4 (invalid argument type for method main)

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

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

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

Choose the correct statementpublic class Circle{ private double radius; public Circle(double radius){ radius = radius; }}

The program has a compilation error because it does not have a main method.

The program will compile, but we cannot create an object of Circle with a specified radius. The object will always have radius 0.

The program has a compilation error because we cannot assign radius to radius.

The program does not compile because Circle does not have a default constructor.
