Java Instance and Static Members

Filed under Java Programming

Each object made will have its own copies of the fields defined in its class. The fields of an object are called instance variables. The principles of the instance variables in an object comprise its state. Two evident stuff can have the same state, if their instance variables have the same principles. The methods of an object define its behavior. These methods are called instance methods. It is vital to note that these methods pertain to each object of the class. This must not be confused with the implementation of the methods, which is shared by all instances of the class. Instance variables and instance methods, which be in the right place to stuff, are collectively called instance members, to distinguish them from static members, which only be in the right place to the class.

Objects of Java

Class Instantiation The process of creating objects from a class is called instantiation. An object is an instance of a class. The object is constructed using the class as a blueprint and is a concrete instance of the abstraction that the class represents. An object must be created before it can ...continue
Basics of Java Programming

Introduction Before embarking on the road to Java programmer certification, it is important to understand the basic terminology and concepts in object-oriented programming (OOP). In this chapter, the emphasis is on providing an introduction rather than an exhaustive coverage. In-depth coverage of the concepts follows in due course in subsequent chapters ...continue
Compiling and Installing a Kernel
1 response - Posted 06.23.08
The preceding discussion has covered the most important options you'll encounter in configuring a kernel to use the networking protocols on your network, and the hardware you use to connect a computer to that network. The process of compiling the kernel, however, is another matter, and one that's not, strictly ...continue
Network Hardware Options
1 response - Posted 06.23.08
The Network Device Support kernel menu contains options related to network hardware. The most important of these options are drivers for specific network cards. The most common types of network cards today are Ethernet devices, but others include traditional local network hardware, long-distance devices, and wireless devices. PC Card devices ...continue
Network Protocol Support
no responses - Posted 06.23.08
The Networking Options kernel menu contains options related to network protocols. You can include or exclude support for entire protocol stacks, and for some (particularly TCP/IP), you can fine-tune the support to optimize the kernel for particular roles, such as router options or packet filtering. continue
Starting Kernel Configuration
1 response - Posted 06.23.08
To configure compile-time kernel options, you must begin with the kernel source code. All major distributions ship with this, but it may or may not be installed by default. Many distributions make changes to the standard kernel (say, to add new drivers that aren't yet standard). You may prefer to ...continue
Linux Kernel Network Configuration

"All roads lead to Rome," the saying goes. Something similar is true of Linux networking, except that in this case, Rome is the Linux kernel. Sooner or later, all network traffic passes through the kernel. Given that not all computers or networks are identical, the Linux kernel includes several options ...continue
