Javaエラーのヘルプ

Question

これはすべてbluejでコンパイルされて実行されるので、メインメソッドは必要ありません。私は多くのエラーを受け取っています。私はそれらを修正する方法がわからないので、javaに新しいです。どんな助けでも大歓迎です。

このエラーは、java.util。*;エラーがあります。

private ArrayList<Property>myProperty;

Answer 1

クラスPropertyメソッドget()定義されていません。

変更Property.get(newMonthlyRent).equals(またProperty.getMonthlyRent().equals(

に、あなたがすべてのプロパティ

ArrayListの上get()方法のリストを保持しているArrayListのmyPropertyでPropertyつのプロパティを混合しているようです1つのPropertyインスタンスが返されますので、addTenant()メソッドでは、myProperty.get(propertyNo).newTenant(tenantName);

ないStringを返し

UPDATE

。 charは、equals()メソッドを持たない。 Property.getLocation() == location
