As discussed previously, Java is a full-featured programming language that is capable of producing full-featured standalone applications. However, the innovations that Java brings to the World Wide Web have created the most interest in Java. This chapter focuses on the ways in which applets can enhance Web pages. Applets can add a variety of enhancements to any Web page, from a personal page to a business page. Within the restrictions placed on applets by browsers and security, you can create astounding applets. Applets can bring sound, animation, user interaction, and much more to your Web pages.

Code conventions are important to programmers for a number of reasons: ? 80% of the lifetime cost of a piece of software goes to maintenance. ? Hardly any software is maintained for its whole life by the original author. ? Code conventions improve the readability of the software, allowing engineers to understand new code more quickly and thoroughly. ? If you ship your source code as a product, you need to make sure it is as well packaged and clean as any other product you create. For the conventions to work, every person writing software must conform to the code conventions. Everyone.

This tutorial examines in detail the Java 2 Platform, Micro Edition (J2ME) and targets the intermediate developer who has a solid background in Java programming and the concepts of object-oriented design and development. You'll start off by examining the background of J2ME and exploring the J2ME configurations and profiles. You'll then step through the process of setting up your development environment for developing J2ME applications.

What is an OS? 1. Tool to make programmer's job easy 2. Resource allocator 3. Control program 4. Tool to facilitate efficient operation of computer system 5. Virtual machine that is easier to understand and program

I hope you enjoy this book as much as I enjoyed writing it. This is a book that represents a lot of work in the area of Java application programming and design. It is designed to hold your hand while you journey through the hills and valleys of Java application programming. You needn't be creating Intranet applications specifically to use this book. It does, however, focus on corporate and Intranet application development. More importantly, its focus is Java application programming. Even though the applications might not be your cup of tea (or coffee!), the concepts and source code presented in this book will be of value.

Open questions are, for example, whether the techniques are sufficient for the description of all important aspects of object-oriented systems, which relationships and consistency criteria exist between them, and how they should be used and reopened during the development process. While some answers to these problems can be found during the attempt to formalize the semantics of UML [BHH+97], other problems and answers can be found most easily by performing \real-world" case studies, which may also serve as a reference for future developers.

This pdf file contains proper notes with example of primitive and Non-primitive process scheduling used in operating system. Process Scheduling The Operating System Kernel  Basic set of primitive operations and processes { Primitive:  Like a subroutine call or macro expansion  Part of the calling process  Critical section for the process { Process  Synchronous execution with respect to the calling process  Can block itself or continuously poll for work  More complicated than primitives and more time and space  Provides a way to provide protected system services, like supervisor call instruction { Protects the OS and key OS data structures (like process control blocks) from interference by user programs { The fact that a process is executing in kernel mode is indicated by a bit in program status word (PSW)

This document contains All database interview question with it's answer. Question 1 What is database? ANSWER: A database is a logically coherent collection of data with some inherent meaning, representing some aspect of real world and which is designed, built and populated with data for a specific purpose. Question 2: What is DBMS? ANSWER: ? Redundancy is controlled. ? Unauthorised access is restricted. ? Providing multiple user interfaces. ? Enforcing integrity constraints. ? Providing backup and recovery.

XML is? a meta markup language used to describe the structure of data. XML has taken the computer industry by storm since its inception and is now the markup language of choice for configuration files, data interchange, B2B transactions, and Java 2 Enterprise architectures. XML is even being used to represent calls to distributed objects through the Simple Object Access Protocol (SOAP), an XML application. XML has numerous advantages including being easy to read, easy to parse, extensible, and widely adopted. In addition, you can define a grammar through a Document Type Definition (DTD) to enforce application-specific syntax.
