Variable description

Type	Variable Name	Purpose	Scope
String	s1	Holds the	Entire programm
		sentence
String	S2	Holds each word	Entire programm
		from the
		sentence
int	j	Loop control	Modified and
		variable	vowel function
BufferedReader	br	Input object	Entire program
Algorithm

Step 1: Create the variables

Step 2: Take the sentence and store in s1

Step 3: Modify the sentence with each character starts with capital letter

Step 4: break the sentence into words

Step 5: Count the number of vowels in each word

Step 6: Display the word, vowel and consonants (length – vowel) in the word
