Parts of a for-statement include the initialization statement, test for continuation, and increment
The do-while statement may be used for iteration
The key difference between a while-statement and do-while statement is at which point the test for continuation is evaluated
The for-each statement may be used for iterating over elements of an ArrayList
The for-each statement may be used for iterating over elements of a HashSet
Iterate over the elements of a HashMap by iterating over the elements of its key set and using keys to access HashMap elements.
There are limitations when using a for-each statement to iterate over a Collection including the inability to modify the collection while iterating
The switch-statement is an alternative way to branch program control flow
The case label is part of a switch-statement that starts a new branch when the switch expression evaluates to a value equal to the case label value
The default branch handles the case when no case label values match
Each code block in a switch-statement must end with a break statement, otherwise execution continues to the statements in the next case, ignoring the case label value.
Stacking case labels without a break statement between is a way to execute one block of code for multiple label matches
The conditional ternary operator is a way to produce different values based on the boolean value resulting from a conditional expression
The ternary operator syntax (? :) has three operands
The ternary operator is like an if-else-statement written and evaluated as a single expression.
