Java

Write a class definition of a class named 'Value' with the following:

• a boolean instance variable named 'modified', initialized to false
• an integer instance variable named 'val'
• a constructor accepting a single parameter whose value is assigned to the instance variable 'val'
• a method 'getVal' that returns the current value of the instance variable 'val'
• a method 'setVal' that accepts a single parameter, assigns its value to 'val', and sets the 'modified' instance variable to true, and
• a boolean method, 'wasModified' that returns true if setVal was ever called.
