Java Swing - 如何获取可见行数

import javax.swing.JList;

public class Main {
  public static void main(String[] argv) throws Exception {
    String[] items = { "A", "B", "C", "D" };
    JList list = new JList(items);
    // Get number of visible items
    int visibleSize = list.getVisibleRowCount();
  }
}
