我有以下的POJOs： public interface Shape {
public double calcArea();
public double calcPerimeter();
}
public class Rectangle implement Shape {
// Various properties of a rectangle
}
pub
String[] boxOptions = {"1","2","4","8","16","20","40","100","400"};
JComboBox box = new JComboBox(boxOptions);
我在程序中有這些確切的代碼行，並沒有得到這個錯誤。我做了一些搜索，我發現的結果有點過頭了。有任何想法嗎？ 的錯誤是： JComboBox is a raw type. Re
我用下面的代碼，我有以下行式安全預警， Type safety: Unchecked cast from Root<capture#5-of ?> to Root<T>
Type safety: Unchecked cast from CriteriaQuery<capture#4-of ?> to CriteriaQuery<T>
有一種方法，以避免它不添加抑制？ CriteriaQuer
