setp1command.java

面向对象的设计思想

public class SetP1Command extends Command {
	int x,y;

  /** Creates new AddCustomerCommand */
  public SetP1Command(int x,int y) {
   this.x= x;
   this.y=y;
  }

  public void execute(DrawModel draw) {
    try {
    	draw.setP1(x,y);
    }
    catch (Exception ex) {
      this.excep = ex;
    }
  }
}
