interpreter commands can find it. See Java 2 SDK Tools for more information. Interpreting and Running the Program Once your program successfully compiles into Java bytecodes, you can interpret and run applications on any Java VM, or interpret and run applets in any Web browser with a Java VM built in such as Netscape or Internet Explorer. Interpreting and running a Java program means invoking the Java VM byte code interpreter, which converts the Java byte codes to platform-dependent machine codes so your computer can understand and run the program.

I also relied on the help of co-workers, friends, and family for whose help I am very grateful. I would like to thank my friend and co-worker, Mary Aline, for providing the French translations for the Chapter 13, Internationalization chapter, and my best friend and husband Jeffrey Pawlan (WA6KBL) who worked with Wolf Geihe (DJ4OA) in Germany to provide the German translations for that same chapter. I do not want to forget Stephanie Wilde, our contract editor at the JDC, who helped with copy editing on the early versions of this material posted to the JDC website. And Dana Nourie, our JDC HTML editor, who in her quest to learn Java, provided unending enthusiasm for this work and contributed to the section on how to set the CLASSPATH environment variable on the Windows platform.

Note: You can find more information on this topic in The Java Tutorial trail on Handling Errors with Exceptions. When you catch exceptions in your code, you should handle them in a way that is friendly to your end users. The exception and error classes have a toString method to print system error text and a printStackTrace method to print a stack trace, which can be very useful for debugging your application during development. But, it is probably better to deploy the program with a more user-friendly approach to handling errors.

Adding Wildcards to the Java Programming Language

Adding Wildcards to the Java Programming Language

Thus they essentially unify the distinct families of classes that parametric polymor- phism introduces. Wildcards are implemented as part of the addition of generics to the Java TM programming language, and is thus deployed world-wide as part of the reference implementation of the Java compiler javac available from Sun Microsys- tems, Inc. By providing a richer type system, wildcards allow for an improved type inference scheme for polymorphic method calls. Moreover, by means of a novel notion of wildcard capture, polymorphic methods can be used to give symbolic names to unspecified types, in a manner similar to the “open” construct known from existential types. Wildcards show up in numerous places in the Java Platform APIs of the newest release, and some of the examples in this paper are taken from these APIs.

operation as a single, easy-to-read line of code that looks exactly like middle school algebra: a = a + b. The line means: Take the value in the variable a, add to it the value of b, and assign the result back to the variable a. Code Listing 1.0 shows a simple expression in Java, and this expression would look the same in many other C-based languages. However, there is an additional advantage to programming an application in Java as opposed to C or C++. Java programs are designed to run on a virtual machine. Figure 2 shows an illustration of native applications versus a Java application. When we write native applications, we must compile our code for each type of system on which we need our application to run. This means we will need to create a version for ARM CPUs if we want our application to run on mobile devices and also create another version of the

Addison Wesley Effective Java   Programming Language Guide pdf

Addison Wesley Effective Java Programming Language Guide pdf

Invoking an alien method from within a synchronized region can cause failures more severe than deadlocks if the alien method is invoked while the invariants protected by the synchronized region are temporarily invalid. (This cannot happen in the broken work queue example because the queue is in a consistent state when processItem is invoked.) Such failures do not involve the creation of a new thread from within the alien method; they occur when the alien method itself calls back in to the faulty class. Because locks in the Java programming language are recursive, such calls won't deadlock as they would if they were made by another thread. The calling thread already holds the lock, so the thread will succeed when it tries to acquire the lock a second time, even though there is another conceptually unrelated operation in progress on the data protected by the lock. The consequences of such a failure can be catastrophic; in essence, the lock has failed to do its job. Recursive locks simplify the construction of multithreaded object-oriented programs, but they can turn liveness failures into safety failures.

Java programming with JNI pdf

Java programming with JNI pdf

All the examples use Java, C, and C++ code, and are written to be portable to both Windows and UNIX-based platforms. To follow the examples, you must have some experience programming in the Java language. In addition, you will also need some experience programming in C or C++. Strictly speaking, a JNI solution could be broken down between Java programming tasks and C/C++ programming tasks, with separate programmers doing each task. However, to fully understand how JNI works in both programming environments, you'll need to be able to understand both the Java and C/C++ code.

LEARNING OBJECTS FOR JAVA PROGRAMMING LANGUAGE

LEARNING OBJECTS FOR JAVA PROGRAMMING LANGUAGE

LEARNING OBJECTS FOR JAVA PROGRAMMING LANGUAGE 4. CONCLUSION Interactive learning object is an idea that many teachers welcome in their search for new methods and support for novice programming students. What subjects to explain with the help of learning object is always a question and in the Codewitz project the need analysis was helpful for the project partners to choose where to begin. To introduce the learning objects to teachers and students is still an ongoing process and all teachers can become partners in Codewitz, get access to the material bank and take part in developing more interactive learning objects.

screen-formatting problems. This is not good programming practice (it would be better to convert them to displayable ASCII characters or decimal representations), but has been done here to keep the code examples and their output brief. In most cases in the example execution sections, the actual strings have been modified to be compatible with the character set requirements of this tutorial. Also, in most examples, we look up and display the actual security provider library used for a given algorithm. This is done to give the user a better feel of which libraries are called for which functions. Why?

Java Programming with Oracle JDBC pdf

With her love, honesty, and tireless support, no matter how wacky some of my adventures or ideas have been, she has always been there as a friend, pointing out that the only limits to my ability were the ones I imagined. As a writing teacher, her advice has been immensely valuable. I am truly grateful to have her help and advice. For the last year, while I have been writing this book, she has pretty much lived without me. Yet she has been my sounding board on many issues related to the book, and it all must have sounded like I was speaking another language. I can't express in words how intensely I love her, but having the time to write this book is good indication of how much she loves me. Thank you Diane!

Java Database Programming with JDBC pdf

Java Database Programming with JDBC pdf

Confused yet? It’s really quite simple: The JDBC defines every aspect of making data-aware Java applications and applets. The low-level JDBC drivers perform the database-specific translation to the high-level JDBC interface. This interface is used by the developer so he doesn’t need to worry about the database-specific syntax when connecting to and querying different databases. The JDBC is a package, much like other Java packages such as java.awt. It’s not currently a part of the standard Java Developer’s Kit (JDK) distribution, but it is slated to be included as a standard part of the general Java API as the java.sql package. Soon after its official incorporation into the JDK and Java API, it will also become a standard package in Java-enabled Web browsers, though there is no definite timeframe for this inclusion. The exciting aspect of the JDBC is that the drivers necessary for connection to their respective databases do not require any pre-installation on the clients: A JDBC driver can be downloaded along with an applet!

tools. Although this book shows a set of Java tools that work nicely with XP, you are not limited to Java and these tools. XP is a language-independent software development approach. [1] Check out http://www.agilealliance.com to learn more about agile processes. While XP works with any language, we believe it works well with Java for a few reasons. Most important is the speed with which Java compiles. XP relies on test-first development in which programmers write tests for code before they write the code. For each new feature, you should write a test and then watch the test run and fail. You should then add the feature, compile, and watch the test run successfully. This implies that you must write a little code, compile, and run the tests frequently, perhaps dozens of times each day. Because Java compiles quickly, it is well suited to the test-first approach.

Introducing Variance into the Java Programming Language DRAFT

Introducing Variance into the Java Programming Language DRAFT

The paper introduces the concepts of variant generic classes and statically safe arrays, in terms of read-only and write-only classes. It briefly explains generic classes in general, but otherwise assumes familiarity with GJ. In the first part, read-only generic classes are introduced. Then, before the other kinds of variance on classes are described, read-only, invariant and write- only arrays are described. Then write-only and bivariant generic classes are introduced.

A Constraint-based ITS for the Java Programming Language

A Constraint-based ITS for the Java Programming Language

not create an entire solution and then ask the system to evaluate it - feedback is only available at each step in the creation of the solution. This method reduces the diffi- culty in evaluation (the system essentially encodes all the explicit possible solutions in its domain model), but it also reduces the freedom of the student, and reduces the to- tal space of valid solutions (if the domain model is incomplete, either intentionally to reduce design time or unintentionally through overlooked concepts). The student may gain misconceptions about domain concepts if a solution that they decide to implement can not be created due to the ITS’s restrictions. RoboProf allows a greater range of solu- tions (in fact, all correct solutions should be accepted by the system), but has two major downsides; it does not give fine-grained feedback (which is important for supporting learning, especially in a domain such as programming with many concepts), and, as it only analyses the output and not the program itself, may accept incorrect solutions (as checking output on a few input cases does not guarantee correctness for all input cases - only by validating the logical structure of the program can this be done). JITS and PROUST’s approaches show the most promise (in terms of accuracy of validation and freedom of solution form); there is explicit mapping of the problem requirements to a high-level description of the expected program. PROUST decomposes the goals of the problem into programming plans, and then matches these plans to part of the input. This idea is intuitive and potentially accurate; what determines the accuracy of the validation is the performance of the system in the act of matching the plans to parts of the solution, and correctness of the design of the plans themselves. JITS employs a similar method; it creates a functional decomposition, rather than a decomposition based on programming plans.
