我正在尝试填充我的gui盒子，当我运行命令gui符合时它给了我一个选择所有者的选项。我正在尝试制作一个gui，当选择所有者时，它会进行计算并填充该字段。

for (String a: ownerList)
for (Property s: propertyList)
{

}
}
计算税收方法是我试图用来填充GUI字段，它可以填充任何字段，如果有人可以指导我，我可以修复哪一个去哪里。
public class CommercialProperty extends Property
{
private String businessName;
private String stateCode;
public CommercialProperty()
{
super();
setBusinessName("");
setStateCode("");
}
public CommercialProperty(Address propertyAddress,double marketValue,int squareFeet, boolean floodZone,String businessName,String stateCode)
{
super (propertyAddress,marketValue,squareFeet,floodZone);
setBusinessName(businessName);
setStateCode(stateCode);
}
public void setBusinessName(String businessName)
{
this.businessName = businessName;
}
public void setStateCode(String stateCode)
{
this.stateCode = stateCode;
}
public String getBusinessName()
{
return businessName;
}
public String getStateCode()
{
return stateCode;
}
public String toString()
{
return(super.toString()+"BusinessName" + businessName + "StateCode" + stateCode);
}
public double calculateTaxes()
{
double tax;
if ((stateCode.equals("TX")) && getSquareFeet() > 1500)
tax = getMarketValue()*0.25;
else if (getSquareFeet() <= 1500 )
tax = getMarketValue() * 0.10;
else
tax = getMarketValue() * 0.20;
return tax;
}
}
还有几个课程，但如果有人可以帮助我如何填充一个我可以在其余部分工作。
