Need help with Java Class in Matlab in windows 10

I have studied examples and had success with the java class example "HelloWorld" but have not been able to get the Addnumber example shown to work. This example was located on this site. Based on post I created a java class as shown below.

package numberpack;
public class Addnumber 
{
    public double add2num( double a1,double a2)
    {
        return a1+a2;
    }
}

I compiled the class and in matlab used:

obj = numberpack.Addnumber

to access the object but get the message: "Unable to resolve the name numberpack.Addnumber."

My path to the class is valid as it is in the file classpath.txt.

Hi,

Please try using () parenthesis for creating the object.

obj = numberpack.Addnumber()

Please refer to the following discussion thread for the reference
