Those two lines are quite weird.

```auto
// there is a number defined
static final int NUM = 2;

// You have an array where you create multiple textboxes. Those get displayed here:
// A for loop which calls actions in multiple tbox objects
for (int i = 0; i != NUM; tboxes[i++].display());

```

For readability I would write it like that:

```auto
for (int i = 0; i<1; i++) {
    tboxes[i].display()
};

```
