Getting information about Constructor

     

In this section you will learn, how to retrieve the information about the constructor by using the getConstructors() method. Here is an example that provides the usage of the getConstructors() method.

Declare a class "Fconstructor" and then create an object of this class and take the reference of the class java.util.Integer.class into it. Make a Constructor named constructor. Now retrieve the name of the constructor by using the getConstructors() method.

Here is the code of the Example :

 

 

 

Fconstructor.java

import java.lang.reflect.*;

public class Fconstructor{
  public static void main(String[] args){
  Class cls = java.lang.String.class;
  Constructor constructor = cls.getConstructors()[0];
  String name;
  name = constructor.getName();  //It'll show java.lang.String
  System.out.println(name);
  }
}

Here is the output of the Example :

C:\roseindia>javac Fconstructor.java

C:\roseindia>java Fconstructor
java.lang.String
