BlueJ Program On Number Of Words Beginning And Ending With A Vowel In A Sentence

Write a program to accept a sentence which may be terminated by either’.’, ‘?’or’!’ only. The words may be separated by more than one blank space and are in UPPER CASE.

Perform the following tasks:

(a) Find the number of words beginning and ending with a vowel.

(b) Place the words which begin and end with a vowel at the beginning, followed by the remaining words as they occur in the sentence.
