Question

Answer 1

The difference depends on who asked the class to be loaded:

• ClassNotFoundException is thrown when the code is directly trying to load a class, passing the String argument representing a Fully Qualified Name of the class.
  • e.g. Class.forName(String), or ClassLoader.loadClass(String).
• NoClassDefFoundError is thrown when the JVM is asked to load a class indirectly.
  • e.g. when class A is using class B and class B is not on classpath, NoClassDefFoundError will be thrown.
