Part A:
Programming project 5.22 on page 205

Part B:
Programming project 5.26 on page 205

Part C:
Fill in the rest of the following class and use it in a main() which exercises its functions.

public class SimpleDate {
// Member variables
  private int month = 1;
  private int day = 1;
  private int year = 1;

// Constructors
  public SimpleDate() {}

  public SimpleDate( int someDay, int someMonth, int someYear) {
    if( dayMonthAgreement( someDay, someMonth) {
      day = someDay;
      month = someMonth;
    }
    if( someYear > 0) {
      year = someYear;
    }
  }

//  The toString function, which is why we built this!
  public String toString() {
    // Write the rest of this code.  Make the string look like "April 2nd, 1984"
    String answer = monthAsString() + " ";
    answer += // put the day here
    answer += // add on the year here.
    return( s);
  }

// Private utility functions:
  private String monthAsString() {
    String answer = ³Unspecified Month²;
    switch( month) {
      // Write the rest of this code
    }
    return( answer);
  }

  private boolean dayMonthAgreement( int aDay, int aMonth) {
    if( (aMonth < 1) || (aMonth > 12)) {
      return( false);
    }
    switch( month) {
      // Write the rest of this code
    }
    return( true);
  }

  private String dayWordEnding() {
    String answer = "";
    switch( day) {
      // Write the rest of this code
    }
    return( answer);
  }
}
