Get All Interfaces
Apache Commons Lang 3.0 is a java library with lot of utilities and reusable components.
This requires the library commons-lang3-3.0.1.jar to be in classpath.
The following example shows using ClassUtils.getAllInterfaces() API.
It returns the list of all interfaces implemented by the given class and its super classes.
package com.bethecoder.tutorials.commons_lang.tests.classes; import java.util.Hashtable; import java.util.List; import java.util.TreeSet; import java.util.Vector; import org.apache.commons.lang3.ClassUtils; public class GetInterfacesTest { /** * @param args */ public static void main ( String [] args ) { List<Class<?>> superClasses = ClassUtils.getAllInterfaces ( Vector. class ) ; System.out.println ( superClasses ) ; superClasses = ClassUtils.getAllInterfaces ( Hashtable. class ) ; System.out.println ( superClasses ) ; superClasses = ClassUtils.getAllInterfaces ( TreeSet. class ) ; System.out.println ( superClasses ) ; } }
