ClassNotFoundException vs NoClassDefFoundError

Vivek R.
20/11/2017 0 0
ClassNotFoundException NoClassDefFoundError
  1. It is an exception and happens due to programmer’s mistake and can be recovered by updating the code.
  2. Thrown when an application tries to load a class through its String name using Class.forName or ClassLoader.findSystem or ClassLoader.loadClass methods.
  3. Thrown by application.
  1. It is an error and doesn’t happen due to programmer’s mistake and can’t be recovered by updating the code.
  2. Thrown if JVM is unable to find the class during runtime which was present at compile time. Ex. removing .class file just before running, will throw error.
  3. Thrown by JVM.
