    copied!<p>I have a small java program that searches the contents of all *.txt files in a folder for a specific string.</p> <p>Example of my problem:</p> <ol> <li>Enter string to find:</li> <li>Enter string to find: 6570</li> <li>Enter string to find: 6570<br> Found 2 time(s) in kyle.txt!<br> Found 2 time(s) in kylezz.txt!<br> Press any key to continue . . .</li> </ol> <hr> <p>The problem:</p> <p>It is searching for 6570 however I pickup results for values like this with that string:</p> <pre> 11111116570111111 657011111 111116570 6570 </pre> <hr> <p>Question: I want to search for only an exact string, eg:"6570". how can I make it return <strong>only</strong> the exact value of 6570? I do not want any extra characters at the beginning or end, only the exact value.</p> <p>Here is my code:</p> <pre><code>import java.io.*; import java.util.*; public class FileScanner { public static void main(String args[]) { System.out.print("Enter string to find: "); Scanner sc = new Scanner(System.in); find(sc.nextLine()); } public static void find(String delim) { File dir = new File("files"); if (dir.exists()) { String read; try { File files[] = dir.listFiles(); for (int i = 0; i &lt; files.length; i++) { File loaded = files[i]; if (loaded.getName().endsWith(".txt")) { BufferedReader in = new BufferedReader(new FileReader( loaded)); StringBuffer load = new StringBuffer(); while ((read = in.readLine()) != null) { load.append(read + "\n"); } String delimiter[] = new String(load).split(delim); if (delimiter.length &gt; 1) { System.out.println("Found " + (delimiter.length - 1) + " time(s) in " + loaded.getName() + "!"); } } } } catch (Exception e) { e.printStackTrace(); } } else { System.out.println("error: dir wasn't found!"); } } } </code></pre> <p>Thanks guys I really hope you can help me with my programming problem. I've been trying to fix it for about a month now and now I'm asking for help.</p>
