Java classes and objects are building blocks of Java programs. Java is a pure object oriented programming language therefore every problem is implemented with help of classes and objects. A Java class is a type definition or a blueprint or a structure for objects that are created from the ...
OOP is a programming paradigmthat assumes centrality in Java because it allows for codes that are modular, reusable, maintainable, or easy to develop. The most characteristic features that it uses include classes and objects, encapsulation, inheritance, polymorphism, and abstraction. Introduction to C...
An object's encapsulation allows it to hide its data and methods. It is one of the fundamental principles of object-oriented programming. Java classes encapsulate the fields and methods that define an object's state and actions. Encapsulation enables you to write reusable programs. It also enable...
We have added two keys as Employee objects and Values as just strings, lets see in which block the keys got stored this time This time, it stored in 8th block and 14th block(why? simple answer because of hashCode of Employee objects), to confirm this, lets override hashCode() of Employe...
Classes, methods, and other internal reflective data are represented directly as objects on the heap (although those objects may not be directly accessible to Java technology-based programs). This not only simplifies the VM internal object model, but also allows classes to be collected by the sam...
Master coding excellence with our Java course and certification. Learn ✔️concepts of core Java & Java EE, ✔️frameworks like Hibernate ✔️Spring & more.
This is a VERY nice book. [...] The highlights of this book are: starts with a procedural approach (objects come later, but they use objects like Strings early on); very readable; LOTS of clear and relevant examples; non-trivial examples (like reading a large text file to compute and...

After graduation, I was unsure about my next steps. During my research, I found Simplilearn's full stack java developer course. They provided online live classes, self-learning resources, and recorded videos for revision. After completing the certification, the placement process began, and within ...
This requirement can be addressed through shared state and condition queues, but you still have to use synchronization by using java.lang.Object.notify() and java.lang.Object.wait() on shared-state objects, which is easy to get wrong. Finally, a common pitfall is to use synchronize and ...
