What is abstract

Question

Abstract class

Answer 1

An abstract class cannot be instantiated (to create a new instance of the class).
Basically an abstract class has a protected constructor that cannot be directly accessed the way i did in the example.

ex/
public abstract class example{}
public class main(){
public static void main(String args[]){
example notAllowed = new example(); // this is illegal
}
}

Answer 2

that can have abstract methods and normal methods.
