Question

I have an array of Objects (file list excatly). How to iterate through this array and delete some Objects (in Java) – depending on the condition ?

File[] files = file.listFiles();
for(File f: files) {
   if(someCondition) {
       // remove
   }
}

I think the best Java way to tackle your problem is to convert your array into a list and use an iterator which allows you to remove objects:

List<File> files = new ArrayList<File>(Arrays.asList(file.listFiles()));
Iterator<File> iterator = files.iterator();
while(iterator.hasNext()){
    File currentFile = iterator.next();
    if(someCondition){
        iterator.remove();
    }
    // other operations
}

You can even convert it again into an array if necessary -even though handling a list is probably more convenient …:

File[] filesArray = files.toArray();
