Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The Java architects have introduced a new file, module-info.java, similar to the existing package-info.java file, found at the root of the module, for example at src/main/java/module-info.java."

A block of code is set as follows:

    module com.steeplesoft.foo.intro {
      requires com.steeplesoft.bar;
      exports com.steeplesoft.foo.intro.model;
      exports com.steeplesoft.foo.intro.api;
    }

Any command-line input or output is written as follows:

$ mvn -Puber install

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "In the New Project window, we select Maven then NetBeans Application."

Warnings or important notes appear like this.

Tips and tricks appear like this.
