Quick Answer
Object cloning creates a copy of an object. Shallow clone (Object.clone()): copies primitive fields by value and reference fields by reference - both original and clone point to the same nested objects. Deep clone: recursively copies all nested objects too. Implement Cloneable interface and override clone(). Alternatively, use copy constructors or serialization for deep copying.
Answer
Cloning creates object copies. Uses Cloneable interface. Shallow copy copies references; deep copy duplicates full object graph.
