How to get value from textfield in another class to use for operations - class

Question

Hey I want to get multiple values from JFrame form and want to use in different class for complex computation of mathematics. I am assigning a simple code to get you an idea. Here, I want to get longitude and latitude from Jframe Class and want to use it in NewJava Class. Problem is I am not getting those input values in this class
NewJFrame
Output: Hour of the Day is: 21
Day of the year is:48
Latitude: 0.0
Longitude: 0.0
Hs:-0.0
delta_s:-0.0
Solar Altitude is; 0.8414709848078965`
NewJFrame Class
