On “Redundant 'static' modifier” warning

Question

Within public interface Constants i declared

static final boolean        TREAT_AS_SOURCE     = true

and got a message that it is a redundantly declared as static .

Help me understand why that is?

Answer 1

在接口中声明的所有字段成员默认为public ， static和final ，因此，再说一遍是多余的。

Answer 2

默认情况下public, static and final接口中的字段是public, static and final 。
