Design 3 UML Diagrams of my java code

Need in only 1 day only 3 UML diagrams for my existing java code. These diagrams will include a Class Diagram,Informal and Formal sequence Diagram as required and need to comply with specific standards of mentioning the controller and command patterns used in code. I understand the code and only require the diagrams; no detailed explanations are needed. I want the diagrams to look professional, so relevant attention to detail for standards compliance is necessary.
