  • In Java, a narrowing conversion is also known as an explicit type conversion or casting.
  • A byte can represent values between -128 to 127.
  • An array, in Java, is an ordered collection of primitives, object references, or other arrays. All the elements of an array must be of the same type, except in case of polymorphism.
  • Array elements are initialized to default values, wherever they are created.
  • The increment operator can be used in either of the two forms given below:
    1. Prefix form: In the prefix form, it appears before the operand. For example, ++a;
    2. Postfix form: In the postfix form, it appears after the operand. For example, a ++;
  • Numeric promotions are used to convert the operands in a numeric expression to a common type before an operation is performed between the operands.
  • In Java, there are two kinds of numeric promotions as follows:
    1. Unary numeric promotion
    2. Binary numeric promotion

    • Pass SCJA Certification Java 1.2 in a first attempt:

    Everything You Want to Know About 70-536 C#

    Earning a Microsoft certification acknowledges your expertise in working with Microsoft products and technologies and sets you apart from the crowd as a development professional. Microsoft certification demonstrates that you have the ability to successfully implement Microsoft business solutions for your organization or client.

    This article will provide a basic understanding of the scope of the certification and will also give details about the certification along with the useful resources to get started.

    Introduction

    With .NET, Microsoft is also espousing a vision, this time about how the Internet can make businesses more efficient and deliver services to consumers. The present enterprise setup’s need to have n-tier architecture with diverse platforms and object models communicating with each other. The present applications are to be created such that those applications have to run in any platform (like Windows, Linux, Mac, Unix etc.) and which consist of components written in many programming languages and object models.

    The framework’s Base Class Library provides a large range of features including user interface, data and data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. The class library is used by programmers, who combine it with their own code to produce applications. Many language vendors have tried to upgrade their languages, but there is a frontier to which they have been victorious since they have to maintain backward competence and face many additional problems too. To resolve the problem of the existing programmers Microsoft has come with a very promising solution “The .NET Platform”.

    .NET provides a number of benefits that will make developers further productive, trim down the number of bugs, alacrity application development, and simplify deployment. IT managers are understandably cautious, since .NET is a new technology that requires a moderately sharp learning curve. For most organizations, however, the benefits will far overshadow the negatives; and with .NET, you’ll see great productivity gains for future development projects.

    Short Notes and Tips to Clear the MCTS 70-502-CSHARP Exam

    Creating a WPF application

      • Windows and navigation applications are installed on a desktop computer. These applications can also run under the full trust environment and have full access to the resources of the computer being used.
      • A XAML browser application runs in Windows Internet Explorer. It runs under a limited set of permissions allowed by the Internet security zone. It can access isolated storage available in the zone. It cannot use a desktop computer’s resources such as the file system, databases, and the Windows registry.
      • A WPF standalone application is installed on a client computer. Hence, it does not require a Web browser. It behaves like a Windows Form application and presents a non-navigational interface to a user. It can also be used by offline users.
      • The WPF technology supports three basic types of applications, namely Windows applications, navigation applications, and XAML browser applications.
      • A WPF application supports Web-style navigation capabilities using Web pages and hyperlinks.
      • The event route for a particular event (for example, the Click event) can travel from the source element, which bubbles upwards through the element tree of its parent element until it reaches the element tree root (can be a page or a window).
      • The Click event is raised when the Button control is clicked.
      • The private void OnChildElementMouseDown(object sender, MouseButtonEventArgs e) {} code segment in the scenario will simply execute the mouse event and the bubbling or tunneling routing process will continue. If you have written e.Handled = true; inside the code statement, the bubbling or tunneling routing process would have been stopped and has marked the event as handled in the event handler.
