[英]Cannot run Swing programs on ubuntu 14.04
I have to do a GUI project for a class, and I cannot run the program I'm writing. 我必须为一个类做一个GUI项目,但是我无法运行正在编写的程序。 I have looked everywhere so I tried to run the simplest program:
我到处都看过,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();
}
});
}
}
I have the java compiler, I know because when I use java -version on my terminal it returns this: 我有Java编译器,因为我在终端上使用java -version时会返回以下内容:
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)
I also have the JRE. 我也有JRE。
When I compile it, I use javac start/HelloWorldSwing.java
(It does compile) But when i try to run it with java start.HelloWorldSwing
it returns this: 当我编译它时,我使用
javac start/HelloWorldSwing.java
(它确实可以编译),但是当我尝试使用java start.HelloWorldSwing
运行它时,它返回以下内容:
