    copied!<p>I have to do a java lab that will take an inputted sentence and create a new string with only the words beginning with vowels. </p> <p>Example: </p> <blockquote> <p>input: It is a hot and humid summer day.</p> <p>output: Itisaand. </p> </blockquote> <p>EDIT: The output I get is anananananan.</p> <p>Here's my code (with comments). The methods are pretty simple. Im just not sure why this isn't working. </p> <pre><code>import java.util.*; public class Driver { public static void main(String[] args) { Scanner console = new Scanner(System.in); System.out.print("Input: "); String input = console.nextLine(); Class strings = new Class(input); // class has constructor for input int beg = 0, end = 0; for (int j = 0; j &lt; input.length(); j++) { if (strings.isVowel(j) &amp;&amp; (input.charAt(j - 1) == ' ' || j == 0)) beg = j; // isVowel finds if there is a vowel at the location else if (strings.endWord(j)) end = j - 1; // endWord finds if there is a space or punctuation at the location if (beg == end - 2) strings.findWord(beg, end); // findWord adds a substring of input from beg to end to the answer } System.out.print("\nOutput: "); strings.printAnswer(); // printAnswer prints the answer } } </code></pre> <p>EDIT: Here is the code for my class.</p> <pre><code>public class Class { String input = "", answer = ""; public Class(String input1) { input = input1; } public boolean isVowel(int loc) { return (input.charAt(loc) == 'a' || input.charAt(loc) == 'e' || input.charAt(loc) == 'i' || input.charAt(loc) == 'o' || input.charAt(loc) == 'u'); } public boolean endWord(int loc) { return (input.charAt(loc) == ' ' || input.charAt(loc) == '.' || input.charAt(loc) == '?' || input.charAt(loc) == '!'); } public void findWord(int beg, int end) { answer = answer + (input.substring(beg, end)); } public void printAnswer() { System.out.println(answer + "."); } } </code></pre>
