Also the quality of the questions at the end of each chapter is marvellous especially Threads and Collections. Do check out this book for better understanding the java concepts. This book will teach you how to effectively use and optimize java in real world. This is one of my favourites books in java written by Joshua Bloch.
Joshua Bloch has been a very popular name in the java community. He also co-authored another famous book for java developers "Java Concurrency In Practice"This book is for the people who wants to utilize java in the best possible way.
Concurrency, Generics and General programming are some of my favourite chapters of this book. Every topic has been explained with the code example , so you are learning in a more practical way. This book you can say is a niche in core java in other words it covers mainly one topic of core java that is concurrency , how two threads work simultaneously. How one can avoid deadlock , How to solve producer consumer problem. If you want to learn real core java concepts then this is the must have book in your shelves.
Collections and concurrency are considered as the real core concepts of the core java. This books cover concurrency really well. All the top investment banks like Goldman Sachs , J P morgan , Morgan Stanley works in concurrency concepts as they deal with share prices.
This book you should read after reading above 3 books so that you dont find difficulty in understanding concepts of concurrency. The topics from which you can learn a lot is Containers in depth , Annotations and Graphical User Interface. This book speciality is that you can find many class diagrams along with well explained coding examples.
This book is must if you like to prepare concepts by writing code examples. This book is also not for a beginner. In the above books GUI or Java swing is not explained well , so for beginners you can read this.
But this book is well mastered in explaining how to use Java swing elements. The good thing about this book is that every class of java swing is given along with the method prototypes.
For every possible element which you can use in GUI , there is an example of that in this book. I think you will really need this book if you are really interested in learning java swing. Every language faces the limited resources problem. Java has been designed to protect users from malicious programs. Programs from an untrusted source for example, the Internet execute in a restricted environment known as a sandbox. The JVM can then prevent those programs from causing mischief.
For example, a Java applet a small program that runs on a Web page usually can't access local files or open network connections to arbitrary computers. These restrictions prevent a Web page from erasing your critical files or sending threatening email from your computer. Data Types and Unicode Software has to manage many types of data, including numbers, dates, currencies, and letters. There are several numeric data types and two character data types, among others.
Whereas the decimal number system is universal, alphabets vary considerably. What do you do if you want to name a variable using Cyrillic letters, for example? To accommodate these variations, Java uses the Unicode character set.
At the basic level, computers only crunch numbers.
When it comes to character data, the computer assigns a number for each letter. Because computers need to communicate with each other, there should be a standard way to map characters to numbers. Both of these used 8 -bit numbers to represent common characters used in the United States. With only 8 bits, these character sets can handle only unique characters including spaces and control characters. However, this capability is not adequate for truly international programs that might encounter languages using a variety of alphabets, such as Farsi or Cyrillic.
Unicode uses bit or even 32 -bit characters that allow it to represent a large number of symbols. The 32 -bit Unicode system with 4. There are even Unicode characters for - eBooks-IT. It is also used by most modern operating systems and We b browsers. That means you can write programs that deal with international character sets.
This Unicode support is provided throughout Java. Not only can your programs handle user input and output in Unicode, but the programs themselves are written using Unicode.
You can name variables and functions using any character set you can represent. Java Tools Many tool vendors provide additional tools for Java some free and some for a price. Because the SDK is command -line oriented, it's no surprise that tool vendors sell IDEs integrated development environments that enable you to edit and compile code from a GUI, improving productivity.
You can download a free version of Forte or download a version with additional features. Note You can read more about tools in Appendix A. For now, just understand that, although these tools can improve productivity, they are not generally discussed in this book.
Once you are comfortable with the basic Java system, you'll be able to use any IDE with ease. Several good editors are on the market. The entry-level version is free and targets the IBM WebSph ere software platform a combination Web server and application server — not bad, considering that IBM is giving away WebSphere with a one-user license.
You can download these two tools and use them to develop powerful applications. Note Be careful if you install these IDEs because they might take a huge amount of disk space.
Also, many are written in Java. This is a good idea, but, because the JVM interprets the programs, the IDEs may require a fast computer and lots of memory to be truly useful.
Other tools are also available, but all you need for now is a text editor. We will be starting with simple programs, so you don't need anything fancy. I use Notepad, the simple editor included with the Windows OS. You can use plenty of other editors, ranging from simple Notepad replacements and vi a common Unix text editor , to large text-editor systems such as Emacs.
The key is to use something you are already comfortable with so you can focus on the Java code instead of on the text editor. The basic components include the compiler javac. The SDK also has tools that handle network programming, but you won't need these for a while yet.
Usually, newer versions of the SDK will work with older versions, but to be safe you should work through the examples using version 1. Installing multiple SDK versions is possible; if you are not careful, however, installing two or more versions can cause problems. For example, if you compile with one version and inadvertently execute with a different runtime version, your program will probably not work properly.
You can have two versions of the SDK installed, however, if you are very careful to keep them separate. If you have 1.
Also, Windows systems have DLLs that are difficult to keep separate between versions. Many of the improvements are performance related, so they don't change your programming. One major change that is apparent is Java's handling of XML. Prior to SDK 1. Now, Java has its own XML parser. Before SDK 1. It is such a relief that SDK 1. Relying on additional, third-party packages for this important functionality was - eBooks-IT.
SDK 1. Java now supports all major locales on the planet, making internationalization easier.
For example, this support affects the handling of currency— Java now makes the euro the default currency used by the java.
