无法在 ubuntu 14.04 上运行 Swing 程序

Question

我必须为一个类做一个 GUI 项目，但我无法运行我正在编写的程序。我到处找，所以我尝试运行最简单的程序：

package start; 
/*
* HelloWorldSwing.java requires no other files. 
*/
  import javax.swing.*;        

  public class HelloWorldSwing {
  /**
  * Create the GUI and show it.  For thread safety,
  * this method should be invoked from the
  * event-dispatching thread.
  */
    private static void createAndShowGUI() {
    //Create and set up the window.
    JFrame frame = new JFrame("HelloWorldSwing");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    //Add the ubiquitous "Hello World" label.
    JLabel label = new JLabel("Hello World");
    frame.getContentPane().add(label);

    //Display the window.
    frame.pack();
    frame.setVisible(true);
    }

public static void main(String[] args) {
    //Schedule a job for the event-dispatching thread:
    //creating and showing this application's GUI.
    javax.swing.SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            createAndShowGUI();
        }
    });
    }
}

我有 java 编译器，我知道，因为当我在终端上使用 java -version 时，它会返回：

openjdk version "9-internal"
OpenJDK Runtime Environment (build 9-internal+0-2016-04-14-195526.buildd.src)
OpenJDK Client VM (build 9-internal+0-2016-04-14-195526.buildd.src, mixed mode)

我也有 JRE。

当我编译它时，我使用javac start/HelloWorldSwing.java（它确实编译） 但是当我尝试使用java start.HelloWorldSwing 运行它时，它会返回：

如果我能在这个问题上得到任何帮助，我将不胜感激

您是否尝试过使用受支持的 Java 版本？尝试 openjdk 8，或下载 Oracle Java 8 版本（当前为 8u102）。
