Thread: Searching code in a list

Hi,
I m beginner in java coding and using netbeans 7.0 to develop a java program

I have a searching code in jlist

public void handleSearchByKey(String oldVal, String newVal) {
    // If the number of characters in the text box is less than last time
    // it must be because the user pressed delete
    if ( oldVal != null && (newVal.length() < oldVal.length()) ) {
        // Restore the lists original set of entries 
        // and start from the beginning
        list.setItems( entries );
    }
 
    // Change to upper case so that case is not an issue
    newVal = newVal.toUpperCase();
 
    // Filter out the entries that don't contain the entered text
    ObservableList<String> subentries = FXCollections.observableArrayList();
    for ( Object entry: list.getItems() ) {
        String entryText = (String)entry;
        if ( entryText.toUpperCase().contains(newVal) ) {
            subentries.add(entryText);
        }
    }
    list.setItems(subentries);
}

here is google like improvement

public void handleSearchByKey(String oldVal, String newVal) {
    // If the number of characters in the text box is less than last time
    // it must be because the user pressed delete
    if ( oldVal != null && (newVal.length() < oldVal.length()) ) {
        // Restore the lists original set of entries 
        // and start from the beginning
        list.setItems( entries );
    }
 
    // Break out all of the parts of the search text 
    // by splitting on white space
    String[] parts = newVal.toUpperCase().split(" ");
 
    // Filter out the entries that don't contain the entered text
    ObservableList<String> subentries = FXCollections.observableArrayList();
    for ( Object entry: list.getItems() ) {
        boolean match = true;
        String entryText = (String)entry;
        for ( String part: parts ) {
            // The entry needs to contain all portions of the
            // search string *but* in any order
            if ( ! entryText.toUpperCase().contains(part) ) {
                match = false;
                break;
            }
        }
 
        if ( match ) {
            subentries.add(entryText);
        }
    }
    list.setItems(subentries);
}

WHAT I WANT IS TO RUN THIS ON PRESSING A BUTTON

Code, and application that uses it from drdobbs.com
