Retrieve only static fields declared in Java class

Question

I have the following class:

public class Test {
    public static int a = 0;
    public int b = 1;
}

Is it possible to use reflection to ge

Answer 1

I stumbled across this question by accident and felt it needed a Java 8 update using streams:

public static List getStatics(Class clazz) {
    List result;

    result = Arrays.stream(clazz.getDeclaredFields())
            // filter out the non-static fields
            .filter(f -> Modifier.isStatic(f.getModifiers()))
            // collect to list
            .collect(toList());

    return result;
}

Obviously, that sample is a bit embelished for readability. In actually, you would likely write it like this:

public static List getStatics(Class clazz) {
    return Arrays.stream(clazz.getDeclaredFields()).filter(f ->
        Modifier.isStatic(f.getModifiers())).collect(toList());
}
