Description: In this assignment you allow the user to choose between 4 patterns. Once a pattern has been chosen the user can also specify the desired size a new Java project that includes 2 files: Pattern.ja Class Pattern: The class Pattern includes 4 methods that print one pattern each. Each pattern includes a parameter called size that corresponds to the number of rows. The patterns above are all of size 5 Here is the UML class diagram of class Pattern Pattem No fields and no constructors are specified (the Java compiler will provide a default constructor) pattern1 size int All methods are underlined. This indicates that they belong to the type and not to a pattern? Size int) specific instance. The methods should be called on the type. No instance of class pattern3 size int Pattern should be created. pattern4 Size int Requirements: 1. Each pattern looks exactly like displayed above when called with size 5 (same number and type of characters) 2. The size of the pattern displayed corresponds to the size passed as an argument 3. Use nested loops to print the patterns (no switch statements or if statements Recommendation: Develop the algorithms by following a step-wise refinement approach that was introduced in the video and practiced in class. Be diligent when drawing the tables and write down the number of circles, spaces, slashes etc. for each of the lines
