I know how how to find files in a folder using Java but how do you search for specific file types. I am looking only include files with the extension .txt in my search.

Answer 1

Cheers. I already looked at that. Got a program that parses a XML and had a play about with it. Can print the contents of tags in my XML. Its just that im trying to parse my XML and have the contents of the starts_with tag to appear in startsWith(or a variable to which this has been assigned) and the contents of the extension tag to appear in endsWith. Totally clueless on how to go about it.
Below is my class. Would be greatful if you have any ideas.
import java.io.File;
public class FindLatestFile {
             public static File getLatest(File thisDir){
                     long latestModDate = -1;
                     File latestFile = null;
                     File[] fileList = thisDir.listFiles();
                     for(int i=0; i < fileList.length; i++){
                         File file = fileList;
     if (file.lastModified() > latestModDate & (file.getName().startsWith("A") & file.getName().endsWith(".txt"))) {
     latestModDate = file.lastModified();
     latestFile = file;
                         return latestFile;
