How to use Splitter class of net.serenitybdd.cucumber.util package

class Test{
    private static int x = 1;
        static class A{
        private static int y = 2;
        public static int getZ(){
            return B.z+x;
        }
    }
    static class B{
        private static int z = 3;
        public static int getY(){
            return A.y;
        }
    }
}

class TestDemo{
     public static void main(String[] args){
        Test t = new Test();
        System.out.println(Test.A.getZ());
        System.out.println(Test.B.getY());
    }
}

public class OuterClass {
     private String someVariable = "Non Static";

     private static String anotherStaticVariable = "Static";  

     OuterClass(){

     }

     //Nested classes are static
     static class StaticNestedClass{
        private static String privateStaticNestedClassVariable = "Private Static Nested Class Variable"; 

        //can access private variables declared in the outer class
        public static void getPrivateVariableofOuterClass(){
            System.out.println(anotherStaticVariable);
        }
     }

     //non static
     class InnerClass{

         //can access private variables of outer class
         public String getPrivateNonStaticVariableOfOuterClass(){
             return someVariable;

     }

         //can access any variable declared inside the Static Nested Class 
         //even if it private
         String var = OuterClass.StaticNestedClass.privateStaticNestedClassVariable; 
         System.out.println(var);
