Java.lang.Class.getDeclaredMethods() Method



The java.lang.Class.getDeclaredMethods() method returns an array of Method objects including public, protected, default (package) access, and private methods, but excludes inherited methods. The method returns an array of length 0 if the class or interface declares no methods, or if this Class object represents a primitive type, an array class, or void


Following is the declaration for java.lang.Class.getDeclaredMethods() method

public Method[] getDeclaredMethods() throws SecurityException


  • NA

Return Value

This method returns the array of Method objects representing all the declared methods of this class.


  • SecurityException -- If a security manager, s, is present.


The following example shows the usage of java.lang.Class.getDeclaredMethods() method.

package com.tutorialspoint;

import java.lang.reflect.*;

public class ClassDemo {

   public static void main(String[] args) {

     ClassDemo cls = new ClassDemo();
     Class c = cls.getClass();

     // returns the array of Method objects 
     Method[] m = c.getDeclaredMethods();
     for(int i = 0; i < m.length; i++) {
        System.out.println("method = " + m[i].toString());

   public ClassDemo() {
      // no argument constructor

   public void showString(String string1) {
      this.string1 = string1;

   private void showInteger(Integer i) {
      this.i = i;

   public Integer i = 10;
   private String string1 = "tutorialspoint"; 

Let us compile and run the above program, this will produce the following result:

method = public static void ClassDemo.main(java.lang.String[])
method = public void ClassDemo.showString(java.lang.String)
method = private void ClassDemo.showInteger(java.lang.Integer)
