A static nested class in Java serves a great advantage to namespace resolution. This is the basic idea behind introducing static nested classes in Java. For example, if you have a class with an exceedingly common name, and in a large project, it is quite possible that some other programmer...

While committing a transaction, if it fails we log the error and then try to recover by rolling back. However this rollback can fail itself which requires another nested Try-Catch block to handle correctly. In fact a common use case that leads to a nested Try-Catch happens when error reco...
if(Car.this.getCarName().equals("Crysler") {...} It is important to note that, although thegetCarName()is aprivatemethod, we are able to access it from the inner class. Static Nested Class In Java, we can also define astaticclass inside another class. Such class is known asstatic ...

To resolve this issue, make sure that the required class is present in the classpath. Check if the class is included in the project’s dependencies or if the JAR file containing the class is properly referenced. Cause 2: Missing Class during Runtime ...
In Java, static nested classes are associated with the outer class. This is why static nested classes can only access the class members (static fields and methods) of the outer class. Let's see what will happen if we try to access non-static fields and methods of the outer class. ...
