[英]Cannot run Swing programs on ubuntu 14.04
我必須為一個類做一個GUI項目,但是我無法運行正在編寫的程序。 我到處都看過,所以我嘗試運行最簡單的程序:
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編譯器,因為我在終端上使用java -version時會返回以下內容:
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。
當我編譯它時,我使用javac start/HelloWorldSwing.java
(它確實可以編譯),但是當我嘗試使用java start.HelloWorldSwing
運行它時,它返回以下內容:

我真的很感激我能在這個問題上獲得任何幫助
您是否嘗試過使用受支持的Java版本? 嘗試使用openjdk 8,或下載Oracle Java 8發行版(當前為8u102)。
