While going through multithreading in java you must have came across this function “Thread.yield This function is special for me because the definition of the function is So let’s go in detail about the native modifier In Java, the native modifier is used to indicate that a method is implemented in a platform-specific manner, typically…
Making a class immutable means that its state cannot be changed once it’s created. In other words, all the fields of the class are set at the time of instantiation and cannot be modified afterward. This can be achieved by using the following techniques: Declaring all fields as final: This ensures that the fields cannot…
Reflection in Java is a mechanism that allows a program to examine and manipulate the structure and behavior of objects at runtime. With reflection, a program can inspect and modify fields, methods, and constructors of a class, as well as access information about the class itself, such as its name, superclass, and interfaces. Reflection is…
In Java,we use these keywords in our development all the time and somehow never realize in which situation we get a compile error until the intellisense prompts us or when we are asked question in interview about it.So let’s see both the keywords in detail.

Just revisiting and explaining myself Polymorphism concept here through a blog post. The words Polymorphism means multiple forms. In Java ,Polymorphism means multiple forms of an object. We shall divide this article into 3 sections. 1.Syntax 2.Calling a variable polymorphically. 3.Calling a method polymorphically. 1.Syntax Now in polymorphism in Java, the thumb key rule to…
Constructors are used every time to initialize instance variables. There are some additional rules associated with constructors that are often asked in interviews.Hence revising those here through a blog post. 1.A constructor is used to initialize instance variables. 2.When an object of an class is created,JVM goes to the class and searches for that matching…
