Design your own Java Class that includes at least 3 data fields, 2 constructors and 4 methods. When designing your class, pick an object that you are familiar with and make it your own, realistic, yet simple design with reasonable data fields and methods. Draw the UML class diagram using PPT or any other graphical editing tool, then, implement the code in Java. Be sure your code compiles and runs as expected. Name your Java file Yournamehw1.java. Name your Java test file Yournamehw1test.java.
