What does the Java prototype pattern refer to?

The Java prototype pattern refers to a design pattern for creating objects by copying existing objects, rather than creating new objects using a constructor. This pattern is very useful when needing to create multiple similar objects, as it can improve the efficiency of object creation. By using the prototype pattern, it is possible to avoid repeatedly executing complex instantiation processes, and instead only need to copy the data of an existing object. In Java, the prototype pattern is typically implemented by implementing the Cloneable interface for object replication.
