Grokking The Java Developer Interview: More Than 200 Questions To Crack The Java, Spring, SpringBoot & Hibernate Interview

- local inner class
- anonymous inner class
local inner class : Local Inner Classes are the inner classes that
are defined inside a block. Generally, this block is a method body.
Sometimes this block can be a for loop , or an if clause. Local Inner
classes are not a member of any enclosing classes. They belong to
the block in which they are defined in, due to which local inner
classes cannot have any access modifiers associated with them.
However, they can be marked as final or abstract. These classes
have access to the fields of the class enclosing it. Local inner class
must be instantiated in the block they are defined in.
Points to remember:
- local inner class cannot be instantiated from outside of
the block where they are defined
- local inner class has access to the members of the
enclosing class
- till Java 1.7, local inner class can access only final local
variable of the enclosing block where they are defined.
But from Java 1.8 onwards, it is possible to access the
non-final local variable of the enclosing block
- the scope of local inner class is restricted to the block
where they are defined
- A local inner class can extend an abstract class or can
implement an interface

Remember, you can only access the block level variables, and
cannot change them. You will get compile time error if you try to
change them:
