:A (protected) integer instance variable named 'val

  • Given the class 'ReadOnly' with the following behavior :A (protected) integer  instance variable  named 'val'.
  • A constructor that accepts an integer and assigns the value of the parameter to the instance variable 'val'.
  • A method  name 'getVal' that returns the value of 'val'.

 

 

  • Write a subclass named 'ReadWrite' with the following additional behavior :Any necessary constructors .
  • a method  named 'setVal' that accepts an integer  parameter and assigns it the the 'val' instance variable .
  • a method 'isDirty' that returns true if the setVal method was used to override the value of the 'val' variable .

 

This is what I have:

 

class ReadWrite extends ReadOnly { super(int val); void setVal(int val){this.val = val;} boolean isDirty() {if (setVal()(return true)) else return false;}}4-13-2017 3-21-31 PM.jpg
