What are some common mistakes people make with generic collections?
Some common mistakes include not using the right type of collection, misunderstanding performance implications, and failing to consider thread safety.
Can you explain why choosing the wrong type of collection is a mistake?
Choosing the wrong type can lead to inefficient data handling. For example, using a List when a Set is needed can cause duplicate entries.
What about performance implications?
Performance can vary significantly between collections. For instance, searching in a List is O(n), while a HashSet offers O(1) average time complexity.
How can I ensure thread safety when using collections?
You can use synchronized collections or consider using concurrent collections like ConcurrentHashMap, which are designed for multi-threaded environments.
