How to find out if a class member is static and a field in Java

How do you find out whether a member of a class is static and a field? I tried using the .getModifiers() method but it didn't return the desired result.

bcMember:

member identifier

identifer of class that contains this member

boolean: true if member is static, false otherwise

boolean: true if member is a field; false otherwise

qualified name of member's (return) type

array qualifier: ' ' means return type is not an array, '[ ]' is a 1D array, '[ ][ ]' is a 2D array, and so on.

signature of member: for a field, it is the name of the field. For a method, it is the name of the method followed by a list of its parameters.

The desired output for the yparser.connection package is:

bcClass(c0,'yparser.connection','Object').

/* public Constructors */
bcMember(m0,c0,true,false,'yparser.connection','','connection(String,String,String,String,String,String)').

/* public Fields */
bcMember(m1,c0,true,true,'String','','quote').
bcMember(m2,c0,true,true,'String','','comma').
bcMember(m3,c0,false,true,'String','','name1').
bcMember(m4,c0,false,true,'String','','role1').
bcMember(m5,c0,false,true,'String','','end1').
bcMember(m6,c0,false,true,'String','','name2').
bcMember(m7,c0,false,true,'String','','role2').
bcMember(m8,c0,false,true,'String','','end2').

/* public Methods */
bcMember(m9,c0,true,false,'void','','dump()').

You know it's a field because it's a Field object.

To determine if it's static:

if(Modifier.isStatic(f.getModifiers()))
    System.out.println("Field is static!");

or

if((f.getModifiers() & Modifier.STATIC) != 0)
    System.out.println("Field is static!");

---

fields[] fld= TheClass.class.getDeclaredFields();
for (Field fldd : fld) {
    if (java.lang.reflect.Modifier.isStatic(fldd.getModifiers())) {
        //Then the fldd is static
    }
}
