Checking String for enum in Java

Question

Write a Java method to check if a given string matches any value in a given enum.

Your method will take two parameters, one a string and one an enum, and return true if the string representation of any of the enum's elements matches the given string, or false otherwise. Note that your method should still function normally if the String parameter is null, and that you aren't allowed to use any external libraries.

Test cases:

public enum E { A, B, C; }

public enum F { X, Y, Z; }

check("a", E.A); // is false (because "A" is uppercase) 
check(null, E.A); // is false
check("C", E.A); // is true
check("X", F.X); // is true
check(null, F.X); // is false
check("y", F.X); // is false

The method has access (as a solver correctly understood) to a generic type E that has the only bound that "E extends Enum(E)".

Reference implementation (Ungolfed):

boolean <E extends Enum<E>> check(String s, E e){
    for(E ex : e.getDeclaringClass().getEnumConstants())
        if(ex.toString().equals(s)) return true;
    return false;
}

Another possible implementation (due to a solution) is (Ungolfed):

public static <E extends Enum<E>> boolean check(String s, E e){
    return java.util.stream.Stream.of(e.getDeclaringClass().getEnumConstants()).anyMatch(x->x.name().equals(s));
}

What I'm looking for is the shortest thing I could put after return (or, as a solutor did, after "(String s,E e)->)".

This is code-golf, so fewest bytes wins!

(String s,E e)->java.util.stream.Stream.of(E.values()).anyMatch(x->x.name().equals(s))

boolean c(String a,Enum e){for(E f:values())if(f.toString().equals(a))return true;return false;}

Test code:

public enum E {
    A,B,C,D,E,F;
    public static void main(String[]a) {
        System.out.println(E.c("a",E));
        System.out.println(E.c("B",E));
        System.out.println(E.c("d",E));
        System.out.println(E.c("C",E));
        System.out.println(E.c("D",E));
        System.out.println(E.c("e",E));
        System.out.println(E.c("F",E));
    }
    boolean c(String a,Enum e){for(E f:values())if(f.toString().equals(a))return true;return false;}
}

Output:

false
true
false
true
true
false
true
