Hello ranchers

This question is from one of mock exam


class EnumTest
{
public enum Color { RED, GREEN, BLUE };
public void foo() {
//code here
System.out.println(c);
}
public static void main(String[] args)
{
EnumTest t1=new EnumTest();
t1.foo();
System.out.println("Hello World!");
}
}
Which code inserted at line 14 causes the foo method to print RED,
GREEN, and BLUE? Answers
A. for( Color c : Color.values())
B. for( Color c = RED; c <= BLUE; c++)
C. for( Color c; c.hasNext() ; c.next())
D. for( Color c = Color[0]; c <= Color[2]; c++)
E. for( Color c = Color.RED; c <= Color.BLUE; c++)

here answer is A, my doubt is we dint define or declared values() method, in java api enum class the method is valueOf(), can anyone please explain me how is answer A

Why dont you try compiling it. if it succeeds then there must be some values() otherwise questn is wrong
