Explanation / Answer

Note:I observed some mistakes in the questions.

1.Didnt mentioned the positionTitle in the UML diagram.

2.In UML diagram given the method declaration as void setPositionTitle(String) .means this method will not return anything.But why In Question 'e' mentioned that this method should return positionTitle.

Actually setter method will not return anything.This is used to set the value of the instance variable .positionTitle.
