inheritance of variable in groovy

Maybe it is the late hours :) But can any one tell why parent class does pull variables from the child

Foo {
   public String myString = "My test string of Foo"

   public printOutString () {
       println this.myString
   }
}

Bar extends Foo {
   public String myString = "My test string of Bar"
}

Foo.printOutString() //prints out "My test string of Foo" as expected

Bar.printOutString() //prints out "My test string of Foo" as not expected thought it would take the String from Bar instead

There is no field inheritance in Groovy nor in Java. You can override the value of the field, as the linked question's answer suggest:

class Foo {
   public String myString = "My test string of Foo"

   public printOutString () {
       myString
   }
}

class Bar extends Foo {
   { myString = "My Bar" }
}


assert new Foo().printOutString() == "My test string of Foo"
assert new Bar().printOutString() == "My Bar"
