There are four types of inner classes: member, static member, local, and anonymous . A member class is defined at the top level of the class. It may have the same access modifiers as variables (public, protected, package, static, final), and is accessed in much the same way as variables of that class.
Read moreWhat is nested and inner class in Java with example?
Non-static nested classes are called inner classes . Nested classes that are declared static are called static nested classes. A nested class is a member of its enclosing class. Non-static nested classes (inner classes) have access to other members of the enclosing class, even if they are declared private.
Read moreWhat is local inner class with example?
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.
Read moreWhen Should inner classes be used?

We can declare a class static by using the static keyword . A class can be declared static only if it is a nested class. It does not require any reference of the outer class. The property of the static class is that it does not allows us to access the non-static members of the outer class.
