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, and user input are shown as follows: "In our code, we have a TransferServiceImpl class, and its constructor takes two arguments:"

A block of code is set as follows:

    public class JdbcTransferRepository implements TransferRepository{ 
      JdbcTemplate jdbcTemplate; 
      public setDataSource(DataSource dataSource) { 
        this.jdbcTemplate = new JdbcTemplate(dataSource); 
    } 
     // ... 
   } 

New terms and important words are shown in bold.
