Constructor getName() method in Java with Examples
  • Last Updated : 29 Oct, 2019

The constructor class provides information about a single constructor for a class and it also provides access to that constructor.
The getName() method of java.lang.reflect.Constructor is used to return this constructor name, as a string. Constructor name is the binary name of the constructor’s declaring class.

Syntax:

public String getName()

Parameters: This method accepts nothing.

Return: This method returns the simple name of the underlying member in String format.

Below programs illustrate getName() method:
Program 1:






// Java program to illustrate getName() method
  
import java.lang.reflect.Constructor;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // create a class object
        Class classObj = String.class;
  
        // get Constructor object array
        // from class object
        Constructor[] con
            s
            = classObj.getConstructors();
  
        // apply getName method
        System.out.println("Constructor : "
                           + cons[0].getName());
    }
}


Output:

Constructor : java.lang.String

Program 2:




// Java program to illustrate getName() method
  
import java.lang.reflect.Constructor;
import java.util.ArrayList;
  
public class GFG {
  
    public static void main(String[] args)
    {
        // get Constructor object for class object
        Constructor constructor
            = ArrayList.class.getConstructors()[0];
  
        // apply getName method
        String name = constructor.getName();
  
        // print result
        System.out.println("Constructor Name : "
                           + name);
    }
}


Output:

Constructor Name : java.util.ArrayList
