}

4.测试 Test.java

package demo03;

public class Test {

    /**

     * @param   args

     */

    public static void main(String[]   args) {

           Storage   store=new Storage(500);

           Producter   p1=new Producter(200,store);

           Producter   p2=new Producter(500,store);

           Producter   p3=new Producter(100,store);

           Customer   c1=new Customer(300,   store);

           Customer   c2=new Customer(400,   store);

           Customer   c3=new Customer(600,   store);

           p1.start();

           p2.start();

           p3.start();

           c1.start();

           c2.start();

           c3.start();

    }
