Explore the differences between a Deque and a Queue in Java, their characteristics, and how to implement them in your code. Learn about their functionalities, use cases, and the core concepts behind these important data structures.
Learn how to implement a stack using a linked list in Java with detailed code examples. Understand the stack operations such as push, pop, and peek while working with LinkedList as the underlying data structure.
Learn about the differences between PriorityQueue and Queue in Java, two essential classes in the Java Collections Framework. This detailed guide with code examples will help you understand their unique features, use cases, and performance characteristics.
Discover the workings of WeakHashMap in Java, a unique collection class that uses weak references to its keys. Learn how it differs from HashMap, its memory management benefits, and how to use it with code examples.
The IdentityHashMap in Java is a specialized implementation of the Map interface that uses reference equality (i.e., ==) instead of object equality (equals()) for comparing keys and values. This feature makes it unique among the standard Map implementations like HashMap. It is useful in situations where object identity matters more than logical equality.
Explore the purpose and benefits of LinkedHashMap in Java. Understand how it works, compare it with HashMap, and learn its real-world applications with code examples.
Understand the significance and use of EnumSet and EnumMap in Java. Learn how these specialized collections can improve performance and simplify your code when dealing with enums in Java. This detailed guide provides code examples and insights into their practical applications.
Learn how to implement a FIFO (First-In-First-Out) cache in Java using the powerful LinkedHashMap. This step-by-step guide provides you with code examples and detailed explanations for creating a custom FIFO cache system.
Learn how to use Comparator.comparing() in Java to simplify sorting and comparisons of complex data types. This detailed guide includes code examples, use cases, and best practices to help you understand and implement this powerful method effectively.
Learn how to create a reverse order comparator in Java with simple code examples and in-depth explanations. Understand how to use Comparator and Collections.sort() to sort elements in descending order.
