Java Utililty Methods Reflection Interface Get

String addInterfaceName(String name)
add Interface Name

interfaceNames.add(name);
return null;

boolean equalInterfaces(Object obj1, Object obj2)
Returns true if the interfaces implemented by obj1's class are the same (and in the same order) as obj2's class.

if (obj1 == obj2) {
 return true;
if ((obj1 == null || obj2 == null) && obj1 != obj2) {
 return false;
Class[] intf1 = getAllInterfaces(obj1);
Class[] intf2 = getAllInterfaces(obj2);
...

List getAllClassesAndInterfaces(Class startClass)
Find all super classes and implemented interfaces for the given class.

ArrayList classes = new ArrayList();
addClassesAndInterfaces(startClass, classes);
return classes;

Class[] getAllInterfaces(Class clazz)
get All Interfaces

if (clazz == null) {
 return new Class[0];
List<Class> classList = new ArrayList<Class>();
while (clazz != null) {
 Class[] interfaces = clazz.getInterfaces();
 for (Class interf : interfaces) {
 if (!classList.contains(interf)) {
...

Class[] getAllInterfaces(Class clazz)
Returns all of the interfaces implemented by a class.

ArrayList result = new ArrayList();
getAllInterfaces(clazz, result);
return (Class[]) result.toArray(new Class[0]);

List getAllInterfaces(Class clazz)
get All Interfaces

return getAllInterfaces(clazz, new ArrayList<Class>());

List getAllInterfaces(Class cls)

Gets a List of all interfaces implemented by the given class and its superclasses.

The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up.

if (cls == null) {
 return null;
List interfacesFound = new ArrayList();
getAllInterfaces(cls, interfacesFound);
return interfacesFound;

List getAllInterfaces(Class cls)

Gets a List of all interfaces implemented by the given class and its superclasses.

The order is determined by looking through each interface in turn as declared in the source file and following its hierarchy up.

if (cls == null)
 return null;
List list = new ArrayList();
while (cls != null) {
 Class[] interfaces = cls.getInterfaces();
 for (int i = 0; i < interfaces.length; i++) {
 if (list.contains(interfaces[i]) == false) {
 list.add(interfaces[i]);
...

List> getAllInterfaces(Class base)
get All Interfaces

List<Class<?>> classes = new ArrayList<>();
Class<?>[] interfaces = base.getInterfaces();
for (Class<?> anInterface : interfaces) {
 classes.add(anInterface);
 classes.addAll(getAllInterfaces(anInterface));
return classes;

Class[] getAllInterfaces(Class clazz)
get All Interfaces

HashSet<Class<?>> interfaces = new HashSet<>();
getAllInterfaces(clazz, interfaces);
return interfaces.toArray(new Class<?>[interfaces.size()]);
