What is the difference between private static int kilos and private int kilos (ignorr the name of the variable is just an example)

Answer 1

when a class field is static it means its the same for all the objects you will create. for example if you have a class with an int age and a static int factor then every object you create can have a different age but all of them will have the same factor even if you change the value of factor using one object

Answer 2

static can be changed out of class. static final cant be changed

Answer 3

static can't change out of class but dinamic ones can.
