What is a class without methods called? I’m trying to understand and learn about classes, so i have the following class “Variables” that doesn’t have methods, only fields, like the field “Server” in a folder called “utilities”:
package com.abc.app.utilities;
public class Variables {
public static String Server="http://192.168.1.29/";
}
then this class is called from a method in another class located in another folder or package this way:
URL url = new URL(Variables.Server + "...");
is this (the without methods) a particular type of class or is a common class despite not having any method?

Raman is right in that all objects inherit the methods of the Object class, so you technically can’t have a class without any methods at all.
But if you’re talking about a class that doesn’t override any of those methods, don’t have methods of its own, and most/all fields are public, then people typically call those POD types, or short for Plain Old Data type.
Something like:
public class Point2D {
public int x;
public int y;
}
would be considered a POD type
