if and the boolean data type

The notes.

• revisit the if statement
• introduce boolean expressions
  1. the value of a boolean is either true or false.
  2. relational operators compare numbers and produce a boolean value. >, <, >=, <=, ==
  3. logical operators take boolean values and produce a new boolean value. &&, ||, !,
• boolean variables: can be assigned the value of a boolean expression.
• methods can return a boolean type.
