Description: The ‘NoClassDefFoundError’ is a type of exception that occurs in the Java runtime environment when the Java Virtual Machine (JVM) or a class loader attempts to load a class and cannot find its definition. This error can arise for various reasons, such as the class being absent from the classpath, typographical errors in the class name, or the absence of necessary libraries. The JVM searches for classes in the classpath, which is a list of locations where the required classes and resources for executing a Java program can be found. When the JVM cannot locate the requested class, it throws this exception, interrupting the program’s execution. This error is fundamental for developers, as it indicates issues in the development environment configuration or project structure. Understanding and properly handling this error is crucial to ensure that Java applications run smoothly and that all dependencies are correctly configured.
