Removing vector elements

Question

hi there
i have a vector, that has the contents of a directory as elements. in the post proccessing phase i trie to remove all elements that are .java files or are class files that end with Options.class or Options$1.class.
i use this code
for(int i=0; i < plugins.size(); i++) {
   theFilename = plugins.elementAt(i).toString();
   System.out.println("TheFilename: "+theFilename);
   if(theFilename.endsWith(".java") ||
      theFilename.endsWith("Options.class") ||
      theFilename.endsWith("Options$1.class")) {
        System.out.println("Removed: "+theFilename);
           plugins.remove(theFilename);
}the problem is, that that code always leaves one element in the vector, that should be sorted out by this loop. anyone an idea ?

Hi jaylogan again,
i read your second answer. I use the methods of the file-class. So it seems better to paste the whole method in here. note, the for loop, that removes filenames is twice there. after first test i found ou, that the second loop is removing the last filename that should not be in the list. that worked as long i had only one plugin in the plugin directory. when i added a second plugin the double for-loop was not working anymore. there is still an element left that should not be in the list.
sourcecode:
public void createPluginList() {
          String theFilename;
          String plugInDir = getCurrDir()+File.separator+"plugins";
          File dir = new File(plugInDir);
          FilenameFilter filter = new FilenameFilter() {
               public boolean accept(File dir, String theName) {
                    return theName.startsWith("Pi");
         String[] contents = dir.list(filter);
         if (contents == null) {
               // Either dir does not exist or is not a directory
          } else {
               for (int i=0; i < contents.length; i++) {
                    plugins.addElement(contents);
          System.out.println("------------");
          for(int i=0; i<plugins.size(); i++) {
               System.out.println(plugins.elementAt(i).toString());
          System.out.println("------------");
          for(int i=0; i < plugins.size(); i++) {
               theFilename = plugins.elementAt(i).toString();
               System.out.println("TheFilename: "+theFilename);
               if(theFilename.endsWith(".java") ||
               theFilename.endsWith("ptions.class") ||
               theFilename.endsWith("ptions$1.class")) {
                    System.out.println("Removed: "+theFilename);
                         plugins.remove(theFilename);
          System.out.println("------------");
          for(int i=0; i < plugins.size(); i++) {          // I dont know why i have to run this
               theFilename = plugins.elementAt(i).toString(); // a second time, but only then
               System.out.println("TheFilename: "+theFilename); // it works
               if(theFilename.endsWith(".java") ||
               theFilename.endsWith("Options.class") ||
               theFilename.endsWith("Options$1.class")) {
                         System.out.println("Removed: "+theFilename);
                         plugins.remove(theFilename);
          System.out.println("------------");
          for(int i=0; i<plugins.size(); i++) {
               System.out.println(plugins.elementAt(i).toString());
