ClassNotFoundException and NoClassDefFoundError in java

ClassNotFoundException : ClassNotFoundException As the name suggests ClassNotFoundException in Java is a subclass of java.lang.Exception and Comes when Java Virtual Machine tries to load a particular class and doesn’t found the requested class in classpath. You need to add required jar in your classpath.
