The TreeMap and TreeSet, both are the part of Collection Framework classes. There exist a few differences as well as a few similarities in their implementation and working. The TreeMap maintains key-value pair on the other hand the TreeSet does not have this feature. In this article, we will discuss the similarities between both classes of Collection Interface. Collection Interface In Java, collection is an object or we can say a container for simplicity that allows us to group several numbers of objects in a single unit. The collection interface is present at the root of all collection framework interfaces. ... Read More

Every time we do surfing on the Web or we download any file from Web, we take a risk of a virus attack. Maybe that file contains some malicious code that can breach the security and gain unauthorized access to system resources. If we are building an application that has users’ sensitive data, for example, a banking system contains confidential data like credit and debit card details, addresses, email and so forth. Then securing those data becomes our foremost priority. In this article, we are going to discuss a few standard practices for protecting the sensitive data of users in ... Read More

Non-blocking Server Java NIO (New Input/Output) is a very powerful networking and file-handling application that functions as an alternative to Java's standard IO API. Due to the addition of more sophisticated features since JDK 4's introduction, it has quickly emerged as the preferred I/O system among numerous engineers. The improved support it offers for file handling and file system features is one of the features that distinguish Java NIO. Since the NIO file classes have such incredible capabilities, it is extensively used in file handling. If you look closely, you'll notice that java.nio package specifies the buffer classes employed by ... Read More

Overview of Node.js vs Java Java has been a long-standing favorite for programmers worldwide, while Node.js is a relatively new JavaScript runtime environment. This article delves into the differences between Node.js and Java and aims to provide a better understanding of both tools and their respective applications. While we may never settle the question of which is ultimately better, gaining insight into these powerful tools can help us make informed decisions about where and when to use them. What Is Node.js? In 2009, Ryan Dahl created Node.js, a cross-platform JavaScript (JS) runtime environment that enables developers to use JavaScript on ... Read More

Overview of Object Model Have you ever thought about how software programs can see and communicate with the components that make them up? The object model is useful in this situation. Developers can represent those components as objects using sophisticated object-oriented techniques thanks to a strong system or interface. The object model is actually so crucial to software development that it's frequently one of the first stages. The object model establishes the framework for a reliable, adaptable, and scalable application design by defining crucial features like inheritance and encapsulation. Are you set to learn more about object-oriented programming? Objects and ... Read More

Numbers in Java It's important to understand that the number class isn't a tangible class, but rather an abstract one. Inside it, we have a set of wrapper classes that define its functions. These wrapper classes include Integer, Byte, Double, Short, Float, and Long. You may notice that these are the same primitive data types we previously discussed, but they're represented as individual classes with capitalized names in keeping with class naming conventions. The compiler automatically converts primitive data types into objects and vice versa, based on the requirements of a particular function or program scope, and the number class ... Read More

Object Compression in Java Java objects can be stored and transmitted more easily by using a method called Java Object Compression to shrink their size. The object will be compressed using a variety of classes and methods during this process, which can greatly decrease the size of the data. The complete amount of information can be retrieved by the recipient by decompressing the compressed object after it has been sent. When dealing with scarce resources, such as network bandwidth or disc space, this method can be helpful. In this article, we will learn more about Java object compression. What ... Read More

NotSerializableException in Java In Java programming, the NotSerializableException is a common exception that occurs when an object of a class is not Serializable. When an object is not Serializable, it means that the object cannot be converted into a sequence of bytes, which is required for data persistence and communication between software components. The NotSerializableException can be thrown either by the serialization runtime or by the object instance itself. This exception is a subclass of ObjectStreamException, which is the superclass for all exceptions related to Object Stream classes. ObjectStreamException extends IOException, indicating that an I/O exception has occurred. Since serialization ... Read More

Introduction to New Features of Java 12 On March 19, 2019, Java 12 was made available. Several new and enhanced features included in Java 12's release make it a worthwhile upgrade over Java 11 in almost every way. Switch Expressions, Default CDS Archives, Shenandoah, and Microbenchmark Suite are a few of the Java 12 features that deserve special mention. To increase Java's productivity, usability, and versatility for coders, these features have been added. We'll talk in-depth about these new capabilities in this article. Switch Expressions (JEP 325) Something interesting to point out is that Java 12 has brought about a ... Read More

Concurrent Collections in Java Java is a well-known computer language that supports concurrency and multithreading. Developers can use the synchronization keyword to guarantee correct synchronization between threads. Additionally, a variety of collections that can be used to hold and manipulate data are offered by Java's collection framework. The synchronized keyword can be used by coders to make these collections thread-safe. The efficient and secure execution of programs involving numerous threads operating concurrently depends on this capability. What Is the Need of Concurrent Collections in Java? ArrayList, LinkedList, HashSet, HashMap, and LinkedHashMap are just a few of the classes in Java's ... Read More
