For bonus credit of 2 points, do one of the following String3 exercises: equalIsNot or countYZ. A hint for equalIsNot : adapt the code from countHi. A hint for countYZ : the logic in your loop will be cleaner if you start by adding a space (" ") to the end of the parameter string and converting it to lower case. You have to complete the main set to get any bonus.

You will find the following String methods to be the most helpful. You will not necessarily need to use all of them.

• char charAt()
• int indexOf(String str)
• int indexOf(String str, int fromIndex)
• int lastIndexOf(String str)
• int lastIndexOf(String str, int fromIndex)
• int length()
• String substring(int beginIndex)
• String substring(int beginIndex, int endIndex)
• String toLowerCase()
