// This file contains several sample problems discussed in lecture.  This

// on your own.

import java.util.*;

public class Methods {
    // Write a method called digitSum that takes an integer n as a parameter
    // and that returns the sum of the digits of n.  Assume that n is >= 0.

    // Write a method called roll7 that simulates the rolling of two dice until
    // their sum is equal to 7.  The method should print each roll and its sum
    // and show a count of how many rolls it took to get to 7, as in:
    //     3 + 5 = 8
    //     2 + 1 = 3
    //     1 + 4 = 5
    //     3 + 4 = 7
    //     sum of 7 after 4 rolls
    // You may assume that an import on java.util is included in the program so
    // that you can construct a Random object.  You must exactly reproduce the
    // format of this sample execution.

    // Write a method called hasOddDigit that takes an integer as a parameter
    // and that returns true if it has an odd digit, false if it does not.

    // Write a method called stutter that takes a string as a parameter and
    // that returns a new string where each letter of the original string has
    // been replaced with two of that letter.  For example, stutter("hello")
    // should return "hheelllloo"

    // Write a method called called season that takes two integers as
    // parameters representing a month and day and that returns a String
    // indicating the season for that month and day. Assume that months are
    // specified as an integer between 1 and 12 (1 for January, 2 for February,
    // and so on) and that the day of the month is a number between 1 and 31.
    // If the date falls between 12/16 and 3/15, you should return "Winter". If
    // the date falls between 3/16 and 6/15, you should return "Spring". If the
    // date falls between 6/16 and 9/15, you should return "Summer". And if the
    // date falls between 9/16 and 12/15, you should return "Fall".

    // On your own: write a method called reverse that takes an integer as a
    // parameter and that returns the reverse of the number.  For example,
    // reverse(38042) should return 24083.

    // on your own: Write a method called noSpaces that takes a String as a
    // parameter and that returns a new string that contains the nonspace
    // characters of the original.  For example, noSpaces("how are you?")
    // should return "howareyou?" (see textbook page 236 for a solution)

    // on your own: Write a method called reverse that takes a string as a
    // parameter and that returns a new string that has the same text in
    // reverse order.  For example, reverse("hello") should return "olleh"
