Day#4 of Java Programming Practice- Two Simple programs

Today's program turned out to be quite simple , so I completed two of them. the first problem is to replace each letter of the string to its subsequent letter and change the case of all vowels in the resulting string to capital. All characters other than alphabets should be left as is.

Today's problem is finding longest word of a sentence.The twist being, in case any of the words has punctuation marks, the punctuation should be ignored while calculating the length of that word.

This problem also seemed simple and I didn't take much time to write this one. In fact I decided to move on to the next problem again today and post two of them together. But on reading the next problem I felt that I will be able to do it better once I am through with regular expressions. So, taking a break to read through the topic of regular expressions before diving into the next problem.   Here is the problem and my solution of the day.
