Prototype Design

Front

What is the main purpose of the Prototype Pattern?

Back

To create objects by copying existing ones instead of using constructors.

Front

What method is used in Java to implement prototyping? Options: clone(), newInstance(), prototype(), Object.assign()

Back

clone()

Front

Which of the following is an advantage of using the Prototype Pattern? Reduces the need for subclassing, Improves performance by avoiding object recreation, Allows for dynamic object cloning, All of the above

Back

All of the above

Front

What is the key difference between shallow and deep copies?

Back

A shallow copy only copies primitive fields but not references.

Front

What happens if a class does not implement Cloneable and calls clone()?

Back

It throws a CloneNotSupportedException

Front

Which situation does not require the Prototype Pattern? Creating objects is expensive, Object structure is complex, Each object needs to be completely unique, We need to improve object creation performance

Back

Each object needs to be completely unique

Front

Why might using .clone() cause issues with nested objects?

Back

It performs a shallow copy by default.

Front

Which of the following is not a disadvantage?

1. Maintenance Overload
2. Potential Security Risks
3. Complex Cloning Logic
4. Intuitive and easy to debug

Back
