Define Employee class in package p1, with id, name and income fields. Define id and name as public, do not define get/set methods for them. Encapsulate 'income' attributes in such a way that, the test code (i.e. where we create the Employee object) should only be able to read the value of income (when test code reside outside the package p1). If the test code resides in package p1, it should also be able to update/set the value of the 'income' field.
