Object Classes
Can someone tell me why im getting an error for each of my other classes? The error is "The public type 'classname' must be defined in it's own file". How do I fix that? My friend said to put it in a package, but I don't know how.
publicclass Shapes{
publicstaticvoid main(String[] args){
Shape[] a =new Shape[5];
a[0] =new Rectangle(3, 4);
a[1] =new Square(5);
a[2] =new Circle(4);
a[3] =new Rectangle(5, 2);
a[4] =new Circle(5);
for (int i = 0; i != a.length; i++){
System.out.println(a[i]);
}
for (int i = 0; i != a.length; i++){
System.out.println(a[i].getArea());
}
for (int i = 0; i != a.length; i++){
a[i].move(2, 3);
}
for (int i = 0; i != a.length; i++){
System.out.println(a[i]);
}
((Rectangle)a[0]).exclusiveRectangleMethod();
((Rectangle)a[1]).exclusiveRectangleMethod();
}
}
