Why we need to use Static keyword inside Static class?

Question

All members must be explicitly specified as static, static class does not automatically make its members static. Static class can contain a collection of static methods.

The definition explains all i.e we need to explicitly give static for methods , members etc inside static class .

What i really didn't get here is if there is a rule like we can declare only static members inside a static class

why doesn't the developer of OOPL make it not mandate . so the compiler should understand(internally) i.e even if we declare a non-static method inside a static class it should understand the method as static (i.e static class can only have static methods) .

I got this doubt when i am working on interfaces see even in case of interfaces all interfaces members are public so we don't declare then public explicitly compiler will understand internally .

All i am looking is for a big WHY not for excuses(it should be like that , its in-build functionality).

there should be duplicate of this somewhere... this is a design decision so we can't answer WHY because we are not designers of the language. — Selman Genç, Feb 16 '15 at 11:05
I like dav_i's answer. On your point about members being public implicitly, that is true but public is the default whereas static is never the default. — Jared Kells, Feb 16 '15 at 11:07
`selman22` that was fact i'm looking why they done that . `dav_i` looks intresting . `downvote` sad , i didnt get why excatly . please do comment so i can correct myself (if there is possible chance) . i'm looking for something i dont know . cheers — super cool, Feb 16 '15 at 12:23

I imagine because a) it is easier to see and b) is consistent:

Easier to see

public static class WithoutStaticMembers
{
    public string GetString() // easy to miss that it is static
    {
        return "string";
    }
}

public static class WithStaticMembers
{
    public static string GetString() // clearly static
    {
        return "string";
    }
}

Consistant

public class NotStaticClass
{
    public static string GetString()
    {
        return "string";
    }
}

public static class StaticClass
{
    public static string GetString()
    {
        return "string";
    }
}
// ...
var s1 = NotStaticClass.GetString();
var s2 = StaticClass.GetString(); // consistent across both static class and not static
