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
Both StAX and SAX are a type of XML parser APIs. Here, API stands for Application Programming Interface and Parser is used to read and extract content from an XML document in desired format. From this line, it is clear that StAX and SAX are used to read XML documents. APIs are a modern way to migrate real time information on the Web. In this article, we will discuss the difference between StAX and SAX Parser in Java. StAX vs SAX Parser XML Its full form is eXtensible Markup Language and it is said to be a data description language. ... Read More
Introduction DNA (Deoxyribonucleic acid) is a long polymer composed of four types of nucleotides: Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). These nucleotides form base pairs, with A pairing with T, and C pairing with G. DNA molecules are generally double stranded, with the two strands running in opposite directions, and the base pairs stacked in the center. This structure is known as the B-form DNA, and it is the most common form of DNA found in cells. Z-DNA: Structure and Sequence There is another form of DNA known as Z-DNA that differs from B-DNA in ... Read More
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
Introduction White adipose tissue (WAT), also known as white fat, is a type of adipose tissue that plays a crucial role in energy storage and metabolism. It is the most abundant form of adipose tissue in the human body and is found primarily in the subcutaneous layer (under the skin) and around the internal organs such as the kidneys and heart. WAT is composed of adipocytes, which are specialized cells that store energy in the form of triglycerides. Adipocytes make up approximately 20-25% of the total cell population in WAT and are surrounded by a network of blood vessels, immune ... Read More
Determining the size of a file on the Internet seems a little tricky, but it is a quite simple and easy task. Java provides some built-in features that can be used for the given task. In this article, we will discuss how to make a connection to the Internet and fetch the size of a given file. How to establish a Connection on Internet using Java URL The modern Internet is all about World Wide Web. Tim Berners-Lee invented a way to locate all the resources on Web and he named it Uniform Resource Locator. It provides the feature ... 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
