public static final

[Jammy Wells]

I have started reading Kathy Sierra Scjp 1.4 book....In the second chapter we have a question which asks indirectly whether U can compile "public static final int k;" as an instance variable declaration or not and the answer provided for this was that U can. I tried writing a class which declares a member variable in above mentioned manner,it gave me a compilation error according to which I shud have initialized this variable by assiging sme value to it.Please tell me whether its smething wrong in the Book's mentioned statement or smething else.

Hi,

Welcome to JavaRanch!

"public static final int i;" is legal, but only if you initialize the variable somewhere, such as in a static initialization block. For example,

class Foo {
    public static final int i;
    static {
        i = 7;
    }
}
