I have done such screen on my android studio and I want to accept those values from user, store it in the variables and after clicking submit button, I want to display those entered value to the user on another screen.

Can you please tell me the way should I write the Java code for this?

Should I have to create a new class for defining and storing variables or I have to write code in MainActivity.java file only?

What are the different packages needed to perform this work? Please give me some example of Java code so I can understand it clearly. Please guide me.
