somethingiswrong.java

初期JAVA学习非常有用的资料。帮助深入了解API。特别是Applet。

//
// This program won't compile because something is wrong.
//
public class SomethingIsWrong {
    public static void main(String[] args) {
        Rectangle myRect;
        myRect.width = 40;
        myRect.height = 50;
        System.out.println("myRect's area is " + myRect.area());
    }
}
