Now

• DrJava Primer
• Expressions and Statements
• Relational and Logical Operators

19
Expressions and Statements

• Summary
• Analogy
• Expression Phrase
• Statement (ends with ) Sentence (ends with
  .)
• Examples

20
Expressions and Statements

• Continuing the analogyyour code will be like a
  story youre telling. You will start with
  expressions which you put together in reasonable
  ways, following the syntax rules, to make valid
  statements. These statements will then be read
  in order from top to bottom (for very simple
  codemore advanced code will be like a choose
  your own adventure story and youll jump around).
  If all works out and you wrote a good story, it
  will produce the appropriate reaction in the
  reader/computer.

21
Relational and Logical Operators

• Relational operators (, etc.)
• Logical operators (AND, OR, NOT)
• tables
