While the JavaBean API specification does not absolutely require you to name your beans in this fashion, using the industry standard Chapter 2: Creating Your Own Beans 37 naming conventions will enhance your bean’s readability and maintainability. The more experienced reader will immediately see the value in any technique that increases code maintainability. If you are a novice programmer, then please take my word for it: Code maintainability is a valued prize sought after by all experienced programmers.
V Provides verbose output. x Extracts the files from the JAR. M Do not create a manifest file. class This will create an archive file in which the first element (myBean) is the name of the archive, and the second element is the name of the manifest. class extensions. In order to extract these files from the JAR, you would create a folder (in our case “myfolder”). jar A manifest file is simply a plain text file that shows the contents of the JAR. It lists all the files contained in a JAR. If you do not create your own manifest and do not use the M option when creating your JAR file, a manifest file will be created for you.

My own personal feeling is that you cannot have too much exception handling. As you can see, JavaBeans have a lot in common with standard Java programs.
