- boolean:
- A data type with only two values,
trueandfalse. - relational operator:
- An operator that compares two values and produces a
booleanindicating the relationship between them. - logical operator:
- An operator that combines boolean values and produces a boolean value.
- short circuit:
- A way of evaluating logical operators that only evaluates the second operand if necessary.
- De Morgan’s laws:
- Mathematical rules that show how to negate a logical expression.
- conditional statement:
- A statement that uses a condition to determine which statements to execute.
- branch:
- One of the alternative sets of statements inside a conditional statement.
- chaining:
- A way of joining several conditional statements in sequence.
- nesting:
- Putting a conditional statement inside one or both branches of another conditional statement.
- flag:
- A variable (usually
boolean) that represents a condition or status. - recursion:
- The process of invoking (and restarting) the same method that is currently executing.
- recursive:
- A method that invokes itself, usually with different arguments.
- base case:
- A condition that causes a recursive method not to make another recursive call.
- binary:
- A system that uses only zeros and ones to represent numbers. Also known as “base 2”.
