Constructor getName() method in Java with Examples

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.
