How to use this site

This site is not a sequential Java textbook. Instead, it is a Java and SQL encyclopedia.

There are two ways to get help.

  1. On the right, you will find the topics sorted by grades.
  2. On the top right you will find a search bar where you can search by keywords eg class diagram, rounding, tracetables, debug etc
  3.  This site is based on the Java by Example approach – less explanation and more examples. View or download the coded examples and study them, code them, run them, edit them, break them . . . this is how professional coders learn.
  4. There are two “Java by Example” textbooks that are a companion to this website. These textbooks offer an sequential learning experience grade by grade.
