Mar 12, 2017 · Main difference is: Decorator is used to decorate individual objects at run-time. Adapter is used to add features to the class and therefore to ALL of its objects. It's true that Adapter targets the class and therefore to ALL of its objects. However, the intent of Adapter is NOT to add feature, but to convert old feature to a new interface.
Jun 2, 2010 · It allows the interface of an existing class to be used as another interface. Example : MouseAdapter. Key differences: Facade defines a new interface, whereas Adapter uses an old interface. Adapter makes two existing interfaces work together. Facade produce a simpler interface Adapter changes an existing interface.
Feb 10, 2016 · 15. Class Adapter is plain old Inheritance, available in every object-oriented language, while Object Adapter is a classic form of an Adapter Design Pattern. The biggest benefit of Object Adapter compared to Class Adapter ( and thus Inheritance ) is loose coupling of client and adaptee. edited Jun 2, 2015 at 20:50.
Jul 10, 2018 · Adapter versus Bridge. The Adapter and Bridge patterns have some common attributes. Both promote flexibility by providing a level of indirection to another object.

Bridge separates invariable part of behaviour (outer) from variable or platform-dependent part (inner). And by interface variation between inner and outer objects: in Proxy interfaces are the same.
Aug 16, 2010 · Adapter adapts a given class/object to a new interface. In the case of the former, multiple inheritance is typically employed. In the latter case, the object is wrapped by a conforming adapter object and passed around. Facade is a simple gateway to a complicated set of functionality. You make a black-box for your clients to worry less.
Dec 6, 2016 · And decorator when a single line is added on top, like @wrap(wArgs); myFunction(args), with the second being syntactic sugar for the first. "Wrapper class" is a phrase that pre-dates design patterns, and bridge, adaptor and decorator are all design patterns that you implement by writing a wrapper class.
May 23, 2017 · 49. The main difference: Class Adapter uses inheritance and can only wrap a class. It cannot wrap an interface since by definition it must derive from some base class. Object Adapter uses composition and can wrap classes or interfaces, or both. It can do this since it contains, as a private, encapsulated member, the class or interface object ...
