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
