The following code contains one compilation error, find it?public class Test {Test() { } // line 1static void Test() { this(); } // line 2 public static void main(String[] args) { // line 3Test(); // line 4}}

At line 4

At line 2, constructor call

At line 1, constructor Tester must be marked public like its class

At line 3, compilation error, ambiguity problem, compiler can't determine whether a constructor
