Advertisements


Description

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

Declaration

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

public Method[] getDeclaredMethods() throws SecurityException

Parameters

  • NA

Return Value

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

Exception

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

Example

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)
