CS – 234. Lab 6 – Iteration 2/27/25 & 3/4/25

Write a class, that has methods to do the following:

a) Receives an integer value and returns a string with:

a. all the digits separated by a space

b. followed by the sum of all the digits. If this sum is greater than 10 then this process is repeated until the sum is less than 10.

Ex: parameter value is 8886

returns a string when output should look like

8 8 8 6 = 3 0 = 3

b) Receives a String (word) and returns:

a. the word with all letters capitalized.

b. Followed by the word with only the first letter capitalized.

Ex: User inputs WiNona

The returned string should look like:

WINONA Winona

c) Receives a sentence and returns:

a. the words in the sentence – one word per line

b. the number of words in the sentence

Ex: Use inputs Winona is a beautiful city in Minnesota

Output should look like

Winona

is

a

beautiful

city

in

Minnesota

The sentence has 7 words.

Test these methods with sample values passed to the methods.

Then write an application that opens an input file “lines.dat” that contains many sentences, one sentence per line, and outputs for each line the sentence followed by the number of words in that sentence.
