factory.java

这个是关于设计模式的一些小例子

package test1;

import test1.Sample;
import test1.SampleA;
import test1.SampleB;

public class Factory{
	public Factory() {
		
	}
	public static Sample create(int which){
		if(which==1)
			return new SampleA();
		else if (which==2)
			return new SampleB();
		
		return null;
	}
}
