Expert written java programs

These books cover a variety of areas, including core Java fundamentals, the Java collection framework, multithreading and concurrency , JVM internals and performance tuning, design patterns , etc. It is not only the most up-to-date book as it covers changes on Java 8, 9, 10, and 11 but also it shows how do you write modern Java code now and coming years.

The book is actually a revised edition of Manning's best-seller Java 8 in Action which was focused on how to code in Java 8 using new features like lambdas, stream, options, and other interesting changes.

In addition to that, this book now covers changes in recent Java versions and includes new library features to support reactive programming, which eventually helps you in writing code that is easier to read and maintain. If you like online courses over books then you can also check out Udemy's The Complete Java MasterClass course, which effectively complements this book and can speed up your learning.

This is also one of my personal favorites. As we are moving gradually, we started from a beginners level to intermediate and now the senior level. Optimizing Java is all about performance monitoring, profiling, and tools used for Java performance monitoring.

This is not the usual programming book. Both beginners and an intermediate programmer can benefit from this book, but it's good to have some Java experience under your belt before reading it. So far, this is the best Java book on performance monitoring. Many people will think that this is a dated book, but to be honest Head First Java is the best book for any programmer who is new in both programming and Java.

The head-first way of explanation is quite phenomenal and I really enjoyed their book. Head First Java covers the essential Java programming knowledge about class, object, thread, collection, and language features, like Generics , Enums , variable arguments , or auto-boxing. They also have some advanced sections on Swing, networking, and Java IO, which makes them a complete package for Java beginners.

This should be your first Java book you look at if you're starting from scratch. If you prefer online courses over books, then you can also check out Udemy's Complete Java MasterClass course.

When I started reading this book back in , I didn't think much about design patterns, how they solve common problems, how to apply a design pattern, what benefits they provide, and all sorts of basic things. But after reading this Java book, I have benefited immensely.

The first chapter on Inheritance and Composition , which is simply fantastic and promotes improved practices by introducing a problem and then the solution. This book also contains helpful bullet points, exercises, and memory maps, which help you to understand design patterns quickly.

If you want to learn core Java design patterns and object-oriented design principles, this is the first Java book you should check out. One point of good news about this book is that the new edition is updated for Java SE 8 , which will teach you how to develop classic GOF design pattern using Java 8 features, like lambda expressions , and streams.

Effective Java is one of the top Java books in my record and one of the most enjoyable. I have high regard for Joshua Bloch, the author, for his contribution to the Java collection framework and Java Concurrency package. Effective Java is best for a seasoned or experienced programmer who is well versed in Java programming.

It's great for programmers who want to share their skills by following programming best practices and who are eager to listen to someone who contributed to the Java development kit JDK. Effective Java consists of a collection of Java programming best practices, ranging from static factories , serialization , equals , and hashcode to generics, enums, varargs, and reflection.

This Java programming book covers almost every aspect of Java in a slightly different way than you are used to. A new edition was released last year that introduced features in the JDK 7, 8, and 9, which was released last year in September. It also has a full chapter on lambdas. This is the best Java book on concurrency and multi-threading, one of the must-reads for core Java developers. Instead of focusing on core Java classes, this book focuses on concurrency issues and problems, like deadlock , starvation, thread-safety, race conditions, and present ways to solve them using Java concurrency classes.

This is the biggest reason I like to read this Java book and read it again and again. One more strong point of concurrency practice in Java is the no-nonsense examples; the examples in this book are clear, concise, and intelligent. This book is also good at explaining what is wrong and why it's wrong and how to make it right, which is essential for any Java book to succeed. In short, this is one of the best books to learn concurrency and multi-threading in Java.

The content is definitely advanced from a beginner's perspective, but surely, this is a must-read book for experienced Java programmers. Btw, if you find this book tough, which is quite obvious because Concurrency itself is a tough topic to digest then I suggest you take a look at the Java Concurrency in Practice Bundle , an online course by Java champion and Java instructor [Dr Heinz M.

Kabutz], it will not only help you to better understand concepts. X Star Pattern 9.

Functions of JVM:. We know that JVM converts the class file into its equivalent executable code. Now if a JVM is in windows environment executable code that is understood by windows environment only. Java, With the help of this course, students can now get a confidant to write a basic program to in-depth algorithms in C Programming or Java Programming to understand the basics one must visit the list Java programs to get an idea. But the platform dependency of the JVM is not considered while saying Java is platform independent because JVM is supplied free of cost through the internet by the sun microsystems.

Platform independence :. Compiled code of a program should be executed in any operating system, irrespective of the as in OS in which that code had been generated. This concept is known as platform independence. Note: In structured programming lang programs, the global variable play a vital role.

But because of these global variables, there is data insecurity in the structured programming lang programs. In this way data is unsecured. But this is not the actual reason.

Assume that it is a project. Now if any upgradation is required, then the client i. Now we should note that it is not guaranteed that the programmers who developed this program will still be working with that company.

Hence this project falls into the hands of new programmers. Automatically it takes a lot of time to study. The project itself before upgrading it. It may not be surprising that the time required for writing the code to upgrade the project may be very less when compared to the time required for studying the project. If the new programmer adds a new function to the existing code in the way of upgrading it, there is no guarantee that it will not affect the existing functions in the code.

This is because of global variables. In this way, data insecurity is created. Three of the global variables may be used only by two functions. But in a structured prog. To avoid this problem, programmers have designed a way such that the variables and the functions which are associated with or operate on those variables are enclosed in a block and that bock is called a class and that class and that class is given a name, Just as a function is given a name.

Now the variables inside the block cannot be called as the local variable because they cannot be called as global variables because they are confined to a block and not global. Hence these variables are known as instance variables.

Therefore a class is nothing but grouping data along with its functionalities. Encapsulations came into existence in order to provide security for the data present inside the program. Note 2: Any object oriental programming language file looks like a group of classes. Everything is encapsulated.

Nothing is outside the class. Java Programs Hello World. Area Of Circle Java Program. Area Of Triangle. Area Of Rectangle Program. Area Of Isosceles Triangle. Area Of Parallelogram. Area Of Rhombus.
