Use while loop in Java Language
Write the method xyzMiddle().
*
* Given a String str, does "xyz" appear in the
* "middle" of the string. To define middle, we'll
* say that the number characters to the left and
* right of the "xyz" must differ by, at most, one.
*
* Examples:
* xyzMiddle("AAxyzBB") returns true
* xyzMiddle("AxyzBB") returns true
* xyzMiddle("AxyzBBB") returns false
*
* @param str the String to examine.
* @return true if xyz is in the "middle" of str.

/**
* Write the method named repeatSeparator().
*
* Given two String inputs, word and separator,
* along with a third int input count, return a
* big String consisting of count copies of word,
* each separated by separator.
*
* Note: This is a very common
* fencepost algorithm, because just like building a
* fence, you need 11 fenceposts to hold up 10 sections
* of fence.
*
* Examples:
* repeatSeparator("Word", "X", 3) returns "WordXWordXWord"
* repeatSeparator("This", "And", 2) returns "ThisAndThis"
* repeatSeparator("This", "And", 1) returns "This"
*
* @param word the first String parameter.
* @param separator the second String parameter.
* @param count the number of times to repeat word.
* @return a new String as described here.

// TODO - Write the repeatSeparator method here.
/**
* Write the method named sameStarChar().
*
* Given a String str, return true if for every
* '*' (star) in the string, if there are chars
* both immediately before and after the star,
* they are the same.
*
* Note: This is a little tricker than it looks.
* One way to look at the problem is to see in
* what circumstances you should return false.
* You only return false if the characters on
* either side of the * are different. That means
* that if there are no characters in front of,
* or behind the *, then you should return true, not false.
*
* Examples:
* sameStarChar("xy*yzz") returns true
* sameStarChar("xy*zzz") returns false
* sameStarChar("*xa*az") returns true
*
* @param str the input String to process.
* @return true if the characters before and after are the same.
