Which exception occurs when a class is not found while dynamically loading a class using the class loaders?
Similarly one may ask, which exception occurs when a class is not found while dynamically?
As the name suggests, ClassNotFoundException is an exception while NoClassDefFoundError is an error. ClassNotFoundException occurs when classpath is does not get updated with required JAR files while error occurs when required class definition is not present at runtime.
Secondly, how do you handle class not found exception? When you get a ClassNotFoundException, it means the JVM has traversed the entire classpath and not found the class you've attempted to reference. The solution, as so often in the Java world, is to check your classpath. You define a classpath on the command line by saying java -cp and then your classpath.
Likewise, what is a class not found exception?
ClassNotFoundException. ClassNotFoundException is a checked exception which occurs when an application tries to load a class through its fully-qualified name and can not find its definition on the classpath. This occurs mainly when trying to load classes using Class. forName(), ClassLoader.
Which ClassLoader is used to load a class?
Java class loaders are used to load classes at runtime. ClassLoader in Java works on three principle: delegation, visibility and uniqueness. Delegation principle forward request of class loading to parent class loader and only loads the class, if parent is not able to find or load class.
