Nested Loops I

Nested Loops II

class String - we have been using the class String for a while, examine the methods that can performed upon a String object. Observe that the class String is contained within the package lang and automatically imported for our use in Java programs.

class Integer - examine the class Integer, including the methods that can performed upon an Integer object. Observe that the class Integer is contained within the package lang and automatically imported for our use in Java programs.

class Paragraph - how can we search the list of sentences?

class ArrayList - examine the list of methods available (including those inherited from another class or in other words, "those passed on to us by another class") for the method iterator.

interface Iterator

classes Calendar, Day, Month, & Year - nota bene: it is known that an error exists within this solution, practicing debugging by finding and fixing the error.
