    <p>I am piping in a file and storing it into a treeset. I am trying to count unique words.. I am placing words that i dont want into a hashset. "a","the", "and"</p> <p>I want to check to see if the file contains those words, before i place them into the TreeSet.. i know i need some sort of if(word == find) ? i just dont know how to do it..</p> <p>Sorry about formatting. its hard to get it correct after you paste.</p> <p>this is what i have..</p> <pre><code>import java.util.Scanner; import java.util.ArrayList; import java.util.TreeSet; import java.util.Iterator; import java.util.HashSet; public class Project1 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); String word; String grab; int count = 0; int count2 =0; int count3 =0; int count4 =0; int number; TreeSet&lt;String&gt; a = new TreeSet&lt;String&gt;(); HashSet&lt;String&gt; find = new HashSet&lt;String&gt;(); System.out.println("Project 1\n"); find.add("a"); find.add("and"); find.add("the"); while (sc.hasNext()) { word = sc.next(); word = word.toLowerCase(); for(int i = 0; i &lt; word.length(); i++ ) { if(Character.isDigit(word.charAt(i))) { count3++; } } //if( a.contains("a") ) //|| word.matches("and") || word.matches("the")|| word.contains("$")) //{ // count2++; // } a.add(word); if (word.equals("---")) { break; } } System.out.println("a size"); System.out.println(a.size()); // count = count2 - count; System.out.println("unique words"); System.out.println(a.size() - count2 - count3); System.out.println("\nbye..."); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
