In the context of Java Inheritance, final and abstract are two important modifiers on deciding whether a class can take part in an inheritance relationship or not.

In this article, we will work with ZIP file system in Java and see how we can move or copy files to ZIP, delete files from ZIP and rename a file in ZIP.

Method reference introduced in Java 8 release along with lambda expression as a mechanism to further shorten the lambda expressions containing a method call.

Lambda Expression is one of the newest features introduced in Java 8 release. It is an expression but in the form of an anonymous function definition.

This article brings a brief introduction to some classes available by the Date/Time Java API, with samples to the main characteristics of each one of them.

In Java, Reflection is a powerful and advanced feature that enables the programmers to inspect or modify the classes, interfaces, and methods of a program running on Java Virtual Machine.

In this article, we explore the types of references in Java which includes strong reference, weak reference, soft reference and phantom reference.

In Java, the interface is a mechanism, using which programmers can connect different software components and make them interact with each other.

In this article, we will learn to use SonarQube to analyze the code quality of existing projects and understand the different terms involved like code smell, code coverage and many others.

Java package corresponds to the file system directory managing different code levels. In this post, we have explored packages in depth.

In Java, it is possible to get the size of an object using its instrumentation package using its premain mechanism and getObjectSize() function

In this article, we will develop a basic calculator in Java using DevOps tools like Apache Maven as a build tool, GitHub for source code management, Jenkins for Continuous integration and deployment and Sonatype Nexus for Artifact repository management.

In Java, all objects have memory located in the heap space where Java's garbage collection constantly remove unused objects to make application memory efficient

In Java, goto is a reserved word but it has not implemented in Java. Hence, we do not have a same goto keyword/ feature as in other languages like C and C++

continue statement is a program flow control statement in Java. It is used to skip the current loop iteration and switch to the next loop iteration.

Generics are a Java paradigm which extends the language's type system, allowing the development of less redundant code with an unnecessary amount of casting

In short, Java does not support inheriting multiple classes and hence, does not support multiple and multipath inheritance. Java supports single, hybrid, hierarchical and multilevel inheritance.

A Wrapper class is a class whose object contains a primitive data types. We can think this as a primitive data type with an additional layer which enables it is get benefits of a custom user defined objects in Java.
