In static class loading, usuall classes are loaded with Java’s “new” operator.When you try to load the class programmatically (here class name is supplied by some property file or from some external source) by invoking the functions of a class loader at run time, It referred as dynamic classloading.
JVM throws NoClassDefFoundException if a class is referenced with Java’s "new" operator (i.e. static loading) but the runtime system or JVM can not find the referenced class.JVM throws ClassNotFoundException exception when an application tries to load in a class through its string name but could not find the definition for the class with the specified name.
