用javac编译出现的错误

Question

代码如下：

import java.awt.*

class JavaGUI

{

    private Frame myFrame;

public JavaGUI()
{
    myFrame = new Frame();
    myFrame.setSize(400,400);
    myFrame.setTitle("The first java GUI application");
    myFrame.setVisible(ture);
}

public static void main(String args[])
{
    System.out.println("Start JavaGUI...");

    JavaGUI mainFrame = new JavaGUI();
}


}

错误提示如下

引用

Exception in thread "main" java.lang.NoClassDefFoundError: JavaGUI/java
Caused by: java.lang.ClassNotFoundException: JavaGUI.java
        at java.net.URLClassLoader$1.run(Unknown Source)

问题补充
我现在弄明白了！

Answer 1

两个错误:import java.awt.* 后少了;
myFrame.setVisible(ture); 中ture应为true
