There's not a JSONArray, only a few JSONObjects. Iterate the keys of the main JSONObject with JSONObject.keys().

public static final String COMPONENT = "component";
public static final String DT = "determinantType";
public static final String D = "determinant": "d";
public static final String HEADER = "header";
public static final String DV = "determinantvalue";

JSONObject jso = getItFromSomewhere();
for (Object key : jso.keys()) {
    JSONObject subset = jso.getJSONObject(key);
    String d = subset.getString(D);
    String header = subset.getString(HEADER);
    String dv = subset.getString(DV);
    System.out.println(key + " " + header + " " + d + " " + dv);
}
