How you can create an object of a class in java?
for creating objects use the new operator along with a call to the constructor. for ex Triangle t = new Triangle(); In this statement the new operator creates a triangle object and the constructor is called which initializes the object and then new returns a reference of the object which is stored in the reference var "t" of type Triangle.
How can you find out a hacker?
Often more than not the term, "hacker" is used to describe someone that uses computers to break computers or deploy attacks on computer systems. The correct term is "cracker".
A hacker is a person that always asks themselves how something works and then figures it out.
To become a hacker you have to find a project where technology does not exist to make things work the way you want them to then use your smarts to find an answer.
Hacker = Inventor of things on top of things already invented.
or else you can say a solutionfinder for silly solutions t
What is the minimum distance to live near high voltage cables?
Technically, the intensity of the electromagnetic fields radiated from electrical transmission lines becomes smaller as the distance from the cable increases, but it never reaches zero. Despite many studies made on the effects of magnetic fields, there is no definitive guide as to what harmful effects high voltage fields have on humans or other living things. The level of risk in being exposed to these fields cannot be categorically stated.
1 what is the main advantage of multiprogramming?
Multiprogramming is the rapid switching of the CPU between multiple processes in memory. It is done only when the currently running process requests I/O, or terminates. It was commonly used to keep the CPU busy while one or more processes are doing I/O. It is now mostly
superceded by multitasking, in which processes also lose the CPU when their time quantum expires.
Multiprogramming makes efficient use of the CPU by overlapping the demands for the CPU and its I/O devices from various users. It attempts to increase CPU utilization by always having something for the CPU to execute.
The prime reason for multiprogramming is to give the CPU something to do while waiting for I/O to complete. If there is no DMA, the CPU is fully occupied doing I/O, so there is nothing to be gained (at least in terms of CPU utilization) by multiprogramming.
What is the difference between RMI and RPC?
RMI simply offers remote access to an object running in another process. But EJB offers far more services than RMI. EJB leverages this remote-object feature of RMI, but also provides other services such as persistence, transaction management, security, and resource management. The EJB server provides all of these complex services which allows EJB developers to worry about business logic instead. For a complete understanding of EJB i suggest Http://edocs.bea.com/wle/rmi/sampejb.htm
What are the advantages and disadvantages of computer in Fashion Education?
Advantages
Sharing devices such as printers saves money. Files can easily be shared between users. Network users can communicate by email. Security is good - users cannot see other users' files unlike on stand-alone machines. A file server is easy to back up as all the data is stored in one place. A computer allows a person to manipulate data easily and quickly, create text documents, edit them, print them, manipulate images, print them, send text and images over the Internet, download information over the Internet, interact with other people easily from home, keep records of transactions, activities, plan trips, and generally do far more than a person without a computer. Computers are very useful to make everyday life a lot easier. You can check the weather, email, search items, buy things type papers and much much more. You can also play games and post blogs and other stuff. People use computers in many ways. Can be used in business, inventions and scanners.
Computers help children to be in control of their experience, to set their own pace, and to select the level of challenge with which they feel comfortable. Computers help children to use all of their senses to extract information. Computers fascinate kids and can draw their full attention, which often results in a deeper focus and concentration. Computers enable children to learn through creating, just as they gain hands-on knowledge and understanding when they build forts, make up stories, and paint, increase their skills. Good educational software enables children to develop and practice a broad range skill. It can help them learn, for example, about letters, numbers, shapes, colours, and rhythm. Good software can also help children develop their understanding of cause and effect, higher order problem solving, procedural thinking, and creative expression. Today, the wide range of multimedia available for kids in India is really amazing. Computers are helpful because they offer a wide range of functions and services that are not available anywhere else. There are four main uses: word processing, internet/communications, digital video/audio composition, and desktop publishing.
Disadvantages
The teenagers of today's society have changed dramatically due to the Computer. Nowadays, the majority of teenagers have a PC and it has played a key role in their lives. Teenagers need to be equipped with knowledge of computer technology, as most things in life require the use of computers. One disadvantage of owning a computer is the information that students can access from the Internet. The Internet has also made the youth of today quite lazy, especially in terms of their education. If a student needs to research information for school, they merely access a relevant site and download the information, rarely paying attention to what is written. Purchasing the network cabling and file servers can be expensive. If the file server breaks down the files on the file server become inaccessible. Viruses can spread to other computers throughout a computer network. There is a danger of hacking, particularly with wide area networks.
Computers are very engaging on children as well as adults. Kids with access to software that is not age appropriate may be exposed to such negative influences as violence, strong language, and over-stimulation from fast-action graphics.
Hackers search computers and/or networks for weaknesses. Hackers that exploit these weaknesses are called Black Hats. The ones who try to fix this weaknesses are called White Hats. Grey Hats are both, usually they're White Hat Hackers by day, and Black Hats by night.

What is zero sequence impedance in transmission line?
In symmetrical components, there are three types of impedances - positive sequence (balanced), negative sequence (unbalanced), and zero sequence (ground).
In a transformer, positive and negative are equal. Ground impedance is determined by the (same factors as the) positive sequence and is based on the flux paths available through the transformer core that can induce ground current.

What are the advantages of CASE tools?
a class of software that automates many of the activities involved in various life cycle phases. For example, when establishing the functional requirements of a proposed application, prototyping tools can be used to develop graphic models of application screens to assist end users to visualize how an application will look after development. Subsequently, system designers can use automated design tools to transform the prototyped functional requirements into detailed design documents. Programmers can then use automated code generators to convert the design documents into code. Automated tools can be used collectively, as mentioned, or individually. For example, prototyping tools could be used to define application requirements that get passed to design technicians who convert the requirements into detailed designs in a traditional manner using flowcharts and narrative documents, without the assistance of automated design software

What is the economic advantages of absorption chiller compared with electric chiller?
· Cost effective and more economical than electrical chillers. Use heat for compression while vapour compression chillers use mechanical compressor for compression purposes which consume a lot of electrical energy.
· Since the compression is caused by heat and does not include any moving mechanical parts, it is less noisy and vibration free.
· For a facility that demands high system reliability, the lower electricity demands of the absorption chiller will reduce emergency generator load requirements.
· Good for the environment as it eliminates the requirement of using CFC and HCFC refrigerants used in electrical chillers which have high global warming potential and instead use natural refrigerants such as water.
