I dont fully understand what abstract classes are for

1. What does it mean when they cant make instances of the classes? does that mean if I were to make an abstract class "student" then I cant do "student student1 = new student"? is that what it means? i cant make an object from it? 2. Can I take methods out of them and override them in other classes? do i have to inherit the abstract class first? 3 Can u only override abstract and virtual methods? if so then whats the difference 4. What does it mean and what can i do when i see a method that isnt abstract like static in an abstract class? is the only way for me to use that method is using another class to inherit from it? Help is greatly appreciated
