In Java, we can also define astaticclass inside another class. Such class is known asstatic nested class. Static nested classes are not called static inner classes. Unlike inner class, a static nested class cannot access the membervariablesof the outer class. It is because thestatic nested cl...

Remember how we have been defining a class inside another class so far for all our coding scenarios? This is typically called as nesting. Also, you might have noticed how we had never made our top level class as static. The reason is plain and simple. Because in Java it can’t be don...
