Warning: Static member accessed via instance reference

Warning:

Static member accessed via instance reference

Shows references to static methods and fields via class instance rather than a class itself.

 

翻译：

通过引用实例来访问静态成员

通过类的实例来显示静态方法和变量的引用，而不是通过类本身

 

分析：

可能是考虑到实例会被回收

 

解决方案：

直接通过类本身来访问静态成员

 

例如：

public class Book() {
    public static final int PAGES = 100;
}

 

//不推荐
Book book = new Book();
int pages = book.PAGES;
//推荐
int pages = Book.PAGES;
