💡 Java Tip : You can use LinkedHashMap to easily implement an LRU (Least Recently Used) Cache. #Java #Collections

Map HashMap LinkedHashMap LRU Cache WeakHashMap Garbage Collection Comparable SortedMap NavigableMap HashTable ConcurrentHashMap ConcurrentSkipListMap EnumMap ImmutableMap There is a lot of Map in Java 😭😭😭

Java Interviews Essentials: HashMap vs TreeMap vs LinkedHashMap ✅ HashMap → Best performance, no order guarantees. TreeMap → Keys always sorted. Good for range queries like subMap(), headMap(), tailMap(). LinkedHashMap → Maintains order. Often used for LRU cache using

Java Tip 💡 Since Java 21 ☕️ the most popular implementations of the Java Collection API like `ArrayList`, `LinkedHashMap`, or `LinkedHashSet` are sequential collections. #java #openjdk #java21 #collections

Least known feature of LinkedHashMap - it can be used as a cache that supports FIFO and LRU eviction policies. You should override the removeEldestEntry(...) method to determine if this map should remove its eldest entry and specify accessOrder=true in constructor to make it LRU

what's the point of a LinkedHashMap if there's no getter for keys that is also explicitly ordered?

Me: Gives a brief prompt about a logic Copilot: Produces code that contains 2 for loops within the same method Me: Can you optimize this code as 2 for loops seems bad performance-wise? Copilot: Gives a method that uses Streams - sort, peek, collect, returns a linkedhashmap
