java - 为什么我运行这个程序时没有弹出一个框架？约格尔

Question

我所做的就是运行 AWT 并显示一个窗口。但我却从 Eclipse 中得到了 JVM 错误。错误如下:

# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (classFileParser.cpp:3174), pid=6688, tid=14480
#  Error: ShouldNotReachHere()
#
# JRE version: 6.0_20-b02
# Java VM: Java HotSpot(TM) 64-Bit Server VM (16.3-b01 mixed mode windows-amd64 )
# An error report file with more information is saved as:
# C:\xampp\htdocs\android\FireRunn\hs_err_pid6688.log

这是运行该程序的实际代码。

import javax.media.opengl.*;
import java.awt.Color;
import java.awt.Frame;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.media.opengl.GLCapabilities;
public class Forest{//open forest

public static void main(String[] args)
{
    Frame frame = new Frame("Hello World");

    GLCapabilities glcapabilities = new GLCapabilities( );
    GLCanvas glcanvas = new GLCanvas( glcapabilities );
    frame.add(glcanvas );

    frame.setSize(300, 300);
    frame.setBackground(Color.WHITE);

    frame.addWindowListener(new WindowAdapter()
    {
        public void windowClosing(WindowEvent e)
        {
            System.exit(0);

    frame.setVisible(true); 

}//close forest
}
        }
    });

您似乎混淆了右括号。这是应该有效的最终代码:

public class Forest{//open forest

    public static void main(String[] args) {
        Frame frame = new Frame("Hello World");

        GLCapabilities glcapabilities = new GLCapabilities();
        GLCanvas glcanvas = new GLCanvas(glcapabilities);
        frame.add(glcanvas);

        frame.setSize(300, 300);
        frame.setBackground(Color.WHITE);

        frame.addWindowListener(new WindowAdapter() {

            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });//close forest
        frame.setVisible(true);
    }
}
