The Unified Modeling Language does not include any design patterns. It is a "visual" language for describing object-oriented designs and other things. It consists mainly of elements and relationships, and also notations for creating diagrams.
A part of the documentation for object-oriented design patterns includes UML-based diagrams which serve to provide examples of how the pattern can possibly be implemented. Keep in mind that these are only examples to help you think.
Also, in English, you should use capital letters when using an acronym such as 'UML'. In English, the first letter of the first word of a sentence is always capitalized. And finally, sentences that are questions should end with a question mark '?' not a period.
I suggest in addition to UML, you should work on improving your written English. This is a very important aspect in any software engineering career, maybe even more important than UML.
