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: "Among them, you will find a folder named lib, which is the folder of interest."

A block of code is set as follows:

    classVals = new ArrayList<String>(); 
      for (int i = 0; i < 5; i++){ 
        classVals.add("class" + (i + 1)); 
    }

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

@relation MyRelation 
 
@attribute age numeric 
@attribute name string 
@attribute dob date yyyy-MM-dd 
@attribute class {class1,class2,class3,class4,class5} 
 
@data 
35,'John Doe',1981-01-20,class3 
30,'Harry Potter',1986-07-05,class1

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: "Select System info from the Administration panel."
