Question

Write a program that will take a sentence (a single String), picks out the individual words (substrings), and puts each of them into a String array. Ex. input: "the lazy dog" output:the

                                                                                              lazy

                                                                                              dog

keep in mind that I am a beginner, so don't make it to difficult for me to undesrstand please. The teacher also said to use indexOf. Also remember to put every individual word into an array before it is spit back out. I've asked this same question twice already and it hasn't been put into an array, so please don't forget to do that. It is the whole point of the problem.

Explanation / Answer

Below is your code: -

StringTester.java

public class StringTester {
   public static void main(String[] args) {
       String line = "the lazy dog";// initializing the string.
       int spaceCount = 0; // number of spaces in text
       for (int i = 0; i < line.length(); i++) {
           if (line.charAt(i) == ' ' && i != line.length() - 1) {
               // checking if character encountered is space and character at
               // index is not last character
               spaceCount++;
           }
       }
       String[] strArr = new String[spaceCount + 1]; // initializing array with
                                                       // number of elements
                                                       // equal to number of
                                                       // words
       String word = line.substring(0, line.indexOf(" ")); // getting first
                                                           // word from line
                                                           // and saving to
                                                           // word
       int count = 0;
       while (!word.isEmpty()) {
           strArr[count++] = word;// inserting word to string array and
                                   // incrementing the counter
           line = line.substring(line.indexOf(" ") + 1) + " "; // deleting
                                                               // first word
                                                               // form line
           word = line.substring(0, line.indexOf(" "));// getting next word
                                                       // from line

       }

       for (int i = 0; i < strArr.length; i++) {
           System.out.println(strArr[i]);// printing array
       }
   }
}
