Hello Friends in this live session i discussed about Difference Between ClassNotFoundException & NoClassDefFoundError #Exception_Handling
ClassNotFoundException:
This Occurs when JVM tries to load a class which is not present in class path .
Can be caught and handled programmatically.

Scenarios :
Incorrect package name specified.
Misspelled class name in code.
Missing dependency JAR files.
Dynamically loading class using reflection . (Class.forName)

NoClassDefFoundError :
This occurs when class was present in compile time but not present at Runtime.
Difficult to handle programmatically.

Scenarios :
Class path misconfiguration
JAR file not included in the classpath
External dependencies missing at runtime
Class file deleted or moved after compilation.

| Feature | ClassNotFoundException | NoClassDefFoundError |
| --------------- | ------------------------------------------- | ------------------------------------------------------------- |
| Type | Checked Exception | Unchecked Error |
| When it occurs | When loading class dynamically | When class was present at compile time but missing at runtime |
| Common cause | Wrong class name or class not in classpath | Class removed or not present in runtime classpath |
| How to fix | Check `Class.forName()` input and classpath | Ensure class is in runtime classpath |
| Example trigger | `Class.forName("com.example.X")` | `new SomeClass()` (if missing at runtime) |
