Here, in this first Java bootcamp, we will start writing code first. If you cannot take a short swim in the pool, you cannot learn swimming. Therefore, we will learn about objects and classes, primitive data types, arrays, logical if-else, switch-case, loop constructs, etc by solving problems.

Let us start with small programs, the result follows; since it is caused by some phenomenon, we will learn the theory thereafter. We will study the problem first, then we solve it and practice some more relevant problems. After that we will discuss theory.

In this way, we will learn how to find Prime, Palindromic Prime, Duck, Armstrong or Narcissistic Number, Special Number, etc. We will learn the Algorithm behind every code.

After all, we want to build many applications with the help of Java, that is our main purpose of learning Java. Although the Abstraction stays behind the curtain, we will learn them with the help of our problems.

As we progress, by solving more than 100 problems from simple to complex, we will learn the Java language basics and its related core concepts.

This book will empower computer science and programming students to learn the language basics of Java; so that, they could build applications in Java. It is for the first time that a book with a "problems-solutions-explanations" approach using “Direct Method”; it is like an intensive coding bootcamp where participants will take active part to develop their logical and analytical thinking so that they could solve interactive problems. For that reason, we will get our head around the basics of Data Structures and Algorithm also.

We are learning the language basics of Java together to solve many types of problems first. It will help us to build applications that are discussed in the next Java bootcamp series, where we will develop applications.
