Java: Get All Static Fields Defined in Class by Reflection

If you want to get all static fields in a class, use code snippet below.
The key part is "Modifier.isStatic", "getDeclaredFields" methods

package com.dukesoftware.reflection;

import java.lang.reflect.Field;
import java.lang.reflect.Modifier;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collectors;

public class ReflectionUtils {
    
    public static List<Field> getStaticFields(Class<?> clazz)
    {
        Field[] declaredFields = clazz.getDeclaredFields();
        return Arrays.stream(declaredFields)
                .filter(field -> Modifier.isStatic(field.getModifiers()))
                .collect(Collectors.toList())
                ;
    }
}
