Answer
HashMap is not synchronized and can enter infinite loops or corrupt data.
A HashMap is not synchronized, meaning multiple threads can modify it simultaneously. This can result in data corruption or infinite loops due to concurrent resizing. In a flash sale system where multiple threads update inventory counts, using a HashMap could lead to incorrect item counts and failed transactions.
