Question

Given class Award :

public class Award {


    /*
     * 
     */

    // fields of the class 

    Award()
    {
        // some initializations


    }

I’m trying to invoke this constructor from Main :

    try
    {
        Award myAward = Award.class.getConstructor().newInstance();
        myAward.calculateAward(); 
    }

    catch (Exception e) 
    {
       e.printStackTrace();
    }

but it goes into the exception block and produces NoSuchMethodException exception .

What’s wrong ?

Thanks !

The issue is your constructor is not public so you will need to use getDeclaredConstructor().newInstance(); or make the constructor public.
