    hi,
    the method of my program return rows with some values... now i need to use condition of values to show. in this case its returning conditional values including null rows.

    how can i remove null rows from arrays ?
    Code:
    public String[][] process(String searchName, String value){
    ..
    String[][] row=null;
    
    Map<String, File> names = new HashMap<String, File>();
    
    try{  
    ..
    ...
    
     row = new String[names.keySet().size()][];
    int i = 0;
     for (String found: names.keySet()) {
    ..
    ..
    [B]if(file.length()>1024){[/B]
    row[i] =new String[]{found, file.getName(), Long.toString(file.length())};
    i++;
    
    
    
    }
    }
    catch(Exception e) {e.printStackTrace() }
     
    return row;
    please help to figure out this....
