extenddemo.java

一些基本的java程序源代码

package point2D;

public class ExtendDemo {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		Point3D p1=new Point3D(1,3,4);
		Point3D p2=new Point3D();
		System.out.printf("p1:(%d,%d,%d)\n",p1.getX(),p1.getY(),p1.getZ());
		System.out.printf("p2:(%d,%d,%d)\n",p2.getX(),p2.getY(),p2.getZ());

	}

}
