It is non-synchronized Manipulation is fast in this because no shifting needs to occur It can be used as a list, stack or queue. The elements are linked using pointers and addresses. Each element is known as a node. It is part of java.util For a detailted tutorial on Java LinkedList ...
It is important to note that HashMap does not guarantee the order of the elements. If you require a specific order, you can use the LinkedHashMap class instead. An Example of Java HashMap Imagine that, as a programmer, you are developing a simple contact management system and want to ...
In Java, a Multimap is a data structure that maps keys to multiple values. Unlike traditional Java maps, which map each key to a single value, a Multimap allows one key to be associated with multiple values. This can be useful for situations where you need to represent a one-to-many ma...

Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
Deque is adouble-ended queuein whichwe can add/delete elements from both ends. A Deque can be implemented using adoubly-linked list/ linked listin Java. Deque can be used in scenarios like designing a ticket counter (detailed explanation done in the previous article). ...
compiler, which includes the linker as part of the compilation process. these compilers automatically invoke the linker to create the final executable file. in other languages, such as java, the linker is typically invoked by language-specific build tools, such as "javac" and "ant." what is...

Default methods, also known as virtual extension methods or defender methods is a non-abstract method, which can be declared inside an interface in Java. If you have been using an interface in Java then you know that it’s not possible to change the structure of the interface, without break...
