Part A. Add the following methods to the Bug4 class of Homework 6C:

• public void move(int n)

  moves the bug n times

• public int moveToBoundary()

  keeps calling move until the bug hits a boundary, returning the number of times the bug had to move to get there.

• public int moveTo(int x, int y)

  keeps calling move until the bug is at position (x, y), returning the number of times the bug had to move to get there. If the bug has moved more than 4 * (maxx + 1) * (maxy + 1) times, return -1. (There are only that many distinct (direction, position) combinations that the bug can assume. If it's not at the desired location by then, it must be in a cycle.)

Part B. In the Word class of Lab 8, add methods

• public void replaceEachConsonantWithX()
• public void replaceEachConsonantGroupWithX()
• public void replaceEachInteriorConsonantGroupWithX()

For example, the word reassuring will be turned into XeaXXuXiXX, XeaXuXiX, and eaXuXi.

Draft: Just implement replaceEachConsonantWithX

Part C. In the Word class of Lab 8, add methods

• public void printLeftTriangle()
• public void printRightTriangle()
• public void printShifts()

that print patterns such as the following

reassuring           g        reassuring
reassurin           ng        eassuringr
reassuri           ing        assuringre
reassur           ring        ssuringrea
reassu           uring        suringreas
reass           suring        uringreass
reas           ssuring        ringreassu
rea           assuring        ingreassur
re           eassuring        ngreassuri
r           reassuring        greassurin
