aaa

aaba
baab
baba
baaa
abaa
abab
abba
D) This is the language of words without bbb, with every bb preceded and followed by an a (that is, no word can start or end wilth bb). All non-empty strings contain at least one a (so b and bb together are not allowed!).

Answer:
A generalized class used only to create related derived classes
Explanation:
An abstract class is a class which cannot be instantiated on its own. It is defined using an abstract keyword. However, an abstract class can be inherited from and the derived class can actually be instantiated. For example:
abstract class A{
}
class B extends A{
void test(){
}
}
Here class A is an abstract class, while class B inherits from A. Now we can create an instance of class B as follows:
B b = new B();
b.test();
