I started implementing various use cases and wrote my own programs. We have all the tools we need to implement a high level of flexibility. I realized how Java is such a powerful language. If we give a fully qualified name which includes a package and the class name, then we will help the compiler locate the class. We can use the import statement in Java to include a package in our code. In Java, we can achieve this kind of scalability by using packages.

The attributes of scalability and maintainability are extremely important characteristics of a software program. By categorizing these classes, it will be easier to maintain them.

During developing an application, the volume of code written is huge.

I realized this when the size of my programs grew larger.

A Java package helps us in categorizing the classes and interfaces.

The reason why TCS Interview Questions is unique is because we know how to guide aspirants cross the finishing line. Having good knowledge of object oriented programming in Java is essential for the TCS Ninja exam. How does a default constructor work? What are the different types of variables that I can create in a class? What is a class in Java? Did I clearly understand all the features of an object oriented programming language? Did I clearly understand all the scope of the different variables and methods? These were some of the most important things that I wanted to be aware of, and be ready for the main exam. The TCS Ninja exam and the following interviews required me to be absolutely comfortable and crystal clear with these concepts. The constructor I found is one of the most important concepts that I needed to be absolutely clear about. As I practiced various different Java programs, I came to be familiar with most of these concepts. It is also important to note that a class can have more than one constructor. One of the main important rules of a constructor that I learned is that they should have the same name as the name of the class. A constructor is involved every time that a new object is created. If we define our own constructor, in that case Java will not build a default constructor. By default, the Java compiler will build a default constructor for any class where we do not define a constructor explicitly. One important topic for the TCS Ninja exam is constructors.

They can be accessed by any method, or a block, or a constructor inside that class. Instance variables are by default initialized when the class is instantiated. The scope of an instance variable is inside the class, but outside any methods. This type of variable is destroyed when the method is completed. A local variable is defined inside a constructor, or a block, or a method. It is important to understand each of these variables. Variables can be of a local variable type, or an instance variable type, or a class variable type. I found this concept of class very interesting as it made me provide some amount of flexibility to the programs. So it is important to remember to create a class holistically and covering all the possible blueprints.

So basically a class defines all the attributes that the different objects belonging to that class will contain. Another word that can be used beside template is blueprint. A class can be defined as the template of an object. I realized it is important to clearly understand the difference between an object and a class. These include polymorphism, inheritance, encapsulation, abstraction, instance, method, and message passing. Java includes most of the features of an object oriented programming language. Even after I learned to use them, I practiced a lot to learn about most of the common best practices to use them efficiently. One of the most important concepts of Java interview for the TCS Ninja exam is related to objects and classes.
