我正在尝试验证我的类构建有什么问题，以使地址类与我的仓库类进行通信。我的 get() 和 set 方法以及 toString() 存在问题。任何帮助将不胜感激
公共类地址{
private String street;
private String city;
private String state;
private int zip;
public Address()
{
setStreet("");
setCity("");
setState("");
setZip(0);
}
public Address(String str, String c, String sta, int z)
{
setStreet(str);
setCity(c);
setState(sta);
setZip(z);
}
public String getStreet()
(
return street;
}
public String getCity()
{
return city;
}
public String getState()
{
return state;
}
public int getZip()
{
return zip;
}
public void setStreet( String str)
{
street = str;
}
public void setCity( String c)
{
city = c;
}
public void setState( String sta )
{
state = sta;
}
public void setZip( String z )
{
zip = z;
}
public String toString()
{
return( " Street " + street + " City " + city +" State " + state + " Zip " + zip);
}
}
必须与以下仓库类通信：
公共类仓库{
private double squareFeetSize;
private double pricePerSquareFoot;
private int televisions;
private int computers;
private Address address;
public Warehouse()
{
setSquareFeetSize(0.0);
setPricePerSquareFoot(0.0);
setTelevisions(0);
setComputers(0);
setAddress(new Address());
}
public Warehouse( double s, double p, int t, int c, Address a)
{
setSquareFeetSize(s);
setPricePerSquareFoot(p);
setTelevisions(t);
setComputers(c);
setAddress(a);
}
public double getSquareFeetSize()
{
return squareFeetSize;
}
public double getPricePerSquareFoot()
{

{

pricePerSquareFoot + " Televisions " + televisions + " Computers " +
computers + " Address " + address.toString());
}
public double calculateWarehouseCharge()
{
double charge = 0.0;
charge = (squareFeetSize * pricePerSquareFoot + (2.25 * televisions) + (5.50 * computers));
return charge;
}
public double purchaseTelevision( int quantity, double price)
{
double cost = 0.0;
if( quantity > televisions)
{
JOptionPane.showMessageDialog(null, "Television Quantity Unavailable");
price = 0.0;
}
else
{
cost = price * quantity;
televisions = televisions - quantity;
}
return cost;
}
public double purchaseComputer( int quantity, double price)
{
double cost = 0.0;
if( quantity > computers)
{
JOptionPane.showMessageDialog(null, "Computer Quantity Unavailable");
price = 0.0;
