Get the list of all the public methods in Java

A list of all the public methods of a class or interface that is represented by an object are provided using the method java.lang.Class.getMethods(). The public methods include that are declared by the class or interface and also those that are inherited by the class or interface.

Also, the getMethods() method returns a zero length array if the class or interface has no public methods or if a primitive type, array class or void is represented in the Class object.

A program that demonstrates this is given as follows −

Example

 Live Demo

import java.lang.reflect.Method;
public class Main {
   public static void main(String[] argv) throws Exception {
      Class c = java.lang.Thread.class;
      Method[] methods = c.getMethods();
      System.out.println("The public methods of the java.lang.Thread class are:\n");
      for (int i = 0; i < methods.length; i++) {
         System.out.println(methods[i]);
      }
   }
}
