for (Product products : this.catalog.getProducts()) {
stdOut.println(products.getCode() + " "
+ products.getDescription());
}
catalog有一个私有属性products
products是关于product的vector
getProducts()是一个返回类型为Vector的函数，就是返回products
public Vector getProducts() {
return products;
}
这是报的错误：Type mismatch: cannot convert from element type Object to Product
stdOut.println(products.getCode() + " "
+ products.getDescription());
}
