In this portion of the pre-work, you’ll read about basic concepts of the Java language. All of this material will be reinforced in the classroom; however, working through this before the bootcamp begins will help you keep up with the pace of the bootcamp instruction, and that instruction will assume that you’ve completed this pre-work.

Required steps

1. Read the following pages of Java Building Blocks.

   • Introduction
   • Types
   • Literals
   • Variables
   • Operators
   • Statements

   Each page includes some examples using JShell, a Java REPL (Read-Evaluate-Print-Loop shell). Please work through these examples. JShell can be launched from a Windows command prompt, Windows PowerShell prompt, or OS X or Ubuntu terminal window

2. After completing the previous step, go to the comments section at the bottom of this page, and post a comment on this pre-work item. Consider the following questions in your comment:

   • What aspects of the Java language do you find most confusing, so far?
   • What unresolved questions do you have (if any)?
