NoClassDefFoundError is thrown when the JVM or a ClassLoader cannot find the definition of a class during runtime, even if it was present during compilation.
This error typically indicates that a required class file is missing from the classpath or that there is a class loading conflict.
NoClassDefFoundError extends LinkageError and provides constructors to create instances with or without a detailed message.
It inherits methods from Throwable for stack trace handling, error message retrieval, and cause analysis.

NoClassDefFoundError
extends LinkageError
Thrown if the Java Virtual Machine or a ClassLoader instance
tries to load in the definition of a class (as part of a normal method call
or as part of creating a new instance using the new expression)
and no definition of the class could be found.
The searched-for class definition existed when the currently
executing class was compiled, but the definition can no longer be
found.
