public class Cup {
private double volume, weight;
private int color;
public void pour () {}
public void drink () {}
public void setVolume (double volume) {
this.volume = volume;
}
public void setWeight (double weight) {
this.weight = weight;
}
public void setColor (int color) {
this.color = color;
}
public double getVolume () {
return volume;
}
public double getWeight () {
return weight;
}
public int getColor () {
return color;
}
public static void main (String args[]) {
Cup cup = new Cup();

第二个问题：
public class Math {
public double area (double radius) {
return (0.5 * Math.PI * radius * radius);
}
public double area (double width, int height) {
return (width * height);
}
public double sumOf (double arg0, double arg1) {
return (arg0 + arg1);
}
}
