• Who is the Java full-stack developer?

  A full-stack developer is a professional who is well-versed in using both front-end and back-end technologies along with databases. Now a Java full-stack developer job guarantee program is someone who is proficient in using full-stack tools and technologies compatible with the Java programming language.

• What is an array in Java?

  When you want to store some data in a contiguous memory location, then an array is used. It is basically an object that stores elements of a similar data type. Java supports two types of arrays - single-dimensional arrays and multidimensional arrays. 

  Example: int a[] = new int[5];

  This statement creates a single-dimensional array and can store 5 values of integer data type. 

• What is inheritance in Java, and how to implement it?

  Inheritance is an important aspect of Object Oriented Programming wherein one class can inherit the features of another class. Inheritance in Java is basically created to allow code reusability, abstraction, and method overloading. It allows the methods and fields of one class (parent class) to be inherited by another class (child class). 

  
  If you want to implement Inheritance in Java, then use the following syntax:

  class child-class extends parent-class

  For example class Triangle extends Shapes

  Here, the word ‘extends’ is used to implement inheritance, and Triangle is the child class that can inherit the properties of parent class Shapes.

• Explain polymorphism with an example.

  Polymorphism is another pillar of Object Oriented programming. Literally, the word polymorphism means many forms. In Java, polymorphism enables users to carry out the same activity in a variety of ways. The concept refers to the capacity of a class to offer several method implementations based on the kind of object it receives as a parameter. 

  Example:

  public area (int base, int height);

  public area (int radius);

  
  Here, the name of the function is the same, but the first one takes two parameters while the second one takes one parameter. Based on how many parameters you pass while calling the function, it will either calculate the area of a triangle or a circle. 

• What are the types of Control Structures in Java?

  Control structures are used in Java when users want to alter the path of code execution and manage how instructions are carried out. Here are the three types of control structures used in Java:

  Control statements - if, else, switch

  Looping statements - for, while, do-while

  Branching statements - break, continue

• How do I debug and run Java Code in Eclipse?

  Here’s how you can run a Java program:

  In the Package Explorer view, hover over the Java class that involves the main method. Right-click on it.

  In the menu that appears, select ‘Run As’, and then click on Java Application.

  
  When you want to debug a Java code, follow these steps:

  In the Package Explorer view, find the Java editor class file and right-click on it. 

  From the menu that appears, select ‘Debug As’ and click on Java Application. 

• Explain OOPS Concepts in Java.

  Object Oriented Programming basically tries to implement real-world entities in programming. Java is also an object-oriented programming language, meaning it uses objects in programming. Some of the important OOPS concepts in Java include class, objects, methods, and four important pillars of OOP, i.e., Abstraction, Encapsulation, Inheritance, and Polymorphism. 

• What is the difference between Abstraction and Encapsulation in Java?

  Abstraction and encapsulation are two of the important pillars of object-oriented programming. While abstraction refers to the process of revealing only the important details and hiding unwanted information, encapsulation refers to the method of binding the data in a single unit or entity so that only the members of a class can access them and not any outsider. 

• What are Interfaces and their types in Java?

  You can think of an interface as a mechanism to implement the abstraction concept in Java. Basically, it is an abstract type that mentions the behavior of a class and specifies what a class must do. Java supports two types of inter-functional interfaces and marker interfaces. 

• Why do we use Multithreading in Java?

  Java’s multithreading functionality enables the simultaneous execution of two or more program components that facilitates optimal CPU efficiency. Each of these components of a program is called a thread. Users need a Thread class to utilize this functionality, and Java runtime will manage to create machine-level instructions and work with the operating systems to run multiple threads in parallel. This parallel execution saves time and does not block the user from carrying out multiple operations.
