Question

Instructions

Today, all input and output has been taken care of for you. All you need to do is finish off the function wordCount that calculates the number of words in a string.

Function Details

Input

• Input has been handled for you. A string will be read in.

Processing

• Complete the wordCount function. Note that you have been given Java comments describing its expected parameters and return value.

/**
 * wordCount (String) -> int
 * Calculates the number of words in a given string
 * @param ?? (str): String of words
 * @return Number of words in the string (int)
 */

• The method takes in a string. It then calculates the the number of words in that string and returns that value.
  

  HINT: This can be done by first splitting the string into individual words using the String.split() method. Then you just need to count how many objects the array holds (and there is an array method for that as well!

Output

• Output has also been taken care of for you.

Sample input/output:

Answer 1

Program

filename: WordCount.java

public class WordCount{

/**
* wordCount (String) -> int
* Calculates the number of words in a given string
* @param inputString String of words
* @return Number of words in the string (int)
*/
public static int wordCount(String inputString) {
int count = 0;
int inWord = 0;
for (char letter : inputString.toCharArray()) {
  
//non-space means were "in a word"
if (letter != ' ') {
inWord = 1;
} else {
// space is the delimiter, but we only want to count a word if
// we were previously "in a word"
if (inWord == 1) {
count++;
inWord = 0;
}
}
}
// Just in case we were "in a word," but never encountered another space
if (inWord == 1) {
count++;
}
return count;
}

public static void main(String args[]){
String input = "I have really enjoyed teaching this class and all of you!";
System.out.println("wordCount(\"I have really enjoyed teaching this class and all of you!\") : " + wordCount(input));
}
}

Output
