content coupling in Java	you directly modify an instance variable of an instance variable	since any modification of data should be easy to find and easy to understand	Ensuring everybody follows the rule that says not to modify the instance variables of objects that are themselves stored in instance variables of another objects Using the immutable or read only interface design patterns Making all instance variables private, and provide accessing methods such as getVal, and setVal. If you do this, you then have confidence that the only places where the variable is accessed and modified are in these methods	that if you want to reuse one component, you will also have to import all the ones with which it is coupled	content coupling	hard to assess	9.2 - Principles Leading to Good Design	you modify a public instance variable in a way that designers did not intend
