面向对象的设计思想

public class SetSelCommand extends Command {
	int x;

  /** Creates new AddCustomerCommand */
  public SetSelCommand(int x) {
   this.x = x;
   System.out.println("Command setsel new "+x);
  }

  public void execute(DrawModel draw) {
    try {
    	draw.setSel(x);
    	System.out.println("Command setsel execute "+x);
    }
    catch (Exception ex) {
      this.excep = ex;
    }
  }
}
