Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String[] items = { "A", "B", "C", "D" };
    JList list = new JList(items);
    list.addListSelectionListener(new MyListSelectionListener());
}

From source file:Main.java

public static void main(String[] argv) throws Exception {

    JList<String> list = new JList<>(model);

    int pos = 0;//from   ww w. ja v a 2s  .  co m
    model.add(pos, "a");

    //Insert an item at the beginning
    model.add(pos, "a");

    // Initialize the list with items
    String[] items = { "A", "B", "C", "D" };
    for (int i = 0; i < items.length; i++) {
        model.add(i, items[i]);
    }

    // Replace the 2nd item
    pos = 1;
    model.set(pos, "b");

    // Remove the first item
    model.remove(pos);

    // Remove the last item
    pos = model.getSize() - 1;
    if (pos >= 0) {
        model.remove(pos);
    }

    // Remove all items
