    	public Person() {

    		this.position = position;
    	}
       
    	public double pay() {
        
    		System.out.print(position+name+"累计奖金为");

package A;
     
    public class Wage extends Component {
        
     
    	protected Component component;
    	public void Decorator(Component component)
    	{
        this.component=component;
     
    }
    	public double pay()
    	{

    	public Increase() {
        
    	
    	}
     
    	public Increase(double yewue) {
        
    	
    		this.yewue = yewue;
    	}
     
    	public double pay()
    	{
        System.out.print("个人业务增长奖金 "+yewue*0.2+"元 ");
