What is the result of compiling and running the following code?public class Tester{static int x = 4;public Tester(){System.out.print(this.x); // line 1Tester();}public static void Tester(){ // line 2System.out.print(this.x); // 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 1 (static x must be only accessed inside static methods)

Compile error at line 3 (static methods can't invoke this)

Compile error at line 2 (constructors can't be static)
