How would I parse for the word "hi" in the sentence "hi, how are you?" or in parse for the word "how" in "how are you?"?
example of what I want in code:
String word = "hi";
String word2 = "how";
Scanner scan = new Scanner(System.in).useDelimiter("\n");
String s = scan.nextLine();
if(s.equals(word)) {
System.out.println("Hey");
}
if(s.equals(word2)) {
System.out.println("Hey");
}
To just find the substring, you can use contains
or indexOf
or any other variant:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
if( s.contains( word ) ) {
// ...
}
if( s.indexOf( word2 ) >=0 ) {
// ...
}
If you care about word boundaries, then StringTokenizer
is probably a good approach.

You can then perform a case-insensitive check (equalsIgnoreCase) on each word.
