Get constructors of a class object

   
 
import java.lang.reflect.Constructor;

public class Main {
  public static void main(String[] args) throws Exception {
    Class clazz = String.class;

    Constructor[] constructors = clazz.getDeclaredConstructors();
    for (Constructor constructor : constructors) {
      String name = constructor.getName();
      System.out.println("Constructor name= " + name);

      Class[] paramterTypes = constructor.getParameterTypes();
      for (Class c : paramterTypes) {
        System.out.println("Param type name = " + c.getName());
