Specialization form of inheritance?

Inheritance refers to the concept by which the features from one class can be extended/made available in other classes.

Java supports 3 forms of inheritance

* Single Inheritance * Multiple Inheritance * Multilevel Inheritance (Can be implemented using interfaces)

How many classes are there of nutrients?

There are six classes of nutrients: carbohydrates, proteins, fats, vitamins, minerals, and water. Each of these nutrient classes plays a unique and essential role in the proper functioning of the human body.

What is an eureka can method?

A 'eureka can' is basically a container with a spout. The spout is positioned a little distance below the top of the container. It is used to find the volume of usually an irregular obect by immersion into water and displacing a volume of water equal to the object's volume.

To find the volume of an object, the eureka can is filled with water. The water spills out level to the rim of the spout.

The obect is then lowered into the eureka can.

The name of the can comes from the legend that Archimedes when getting into his filled-up bath, he realised that the volume of water that was spilled over was equal to that part of him that was in the bath...and thus "Eureka!", Ive found it!

The eureka can is also known as a displacement vessel.

Hope this helps

What is the difference between the properties of a substance and the properties of an object?

The properties of a substance are inherent in that substance, for example steel, but steel can be used to make all sorts of different objects. Each object has its own properties, but the basic property of steel is the same in all of them (for the same grade of steel)

What is an interface?

An interface is the place where two different things meet and interact. This term often comes up with regard to computers. Data processing takes place inside the computer, and thoughts take place inside the user of the computer, and they meet at an interface, which is a keyborad and a monitor screen (and usually speakers as well).

Normally, the term interface most commonly used in networking world.Every networking equipments of the world are connected through interfaces in order to make intelligible communications such as-routers, switches, hubs-these devices has interfaces. One important characteristics of interface is that they they should have the combination of input and output.

What is the sociological term for a middle class parent who can afford things a working class parent can't?

This situation can be referred to as "economic privilege" or "class advantage". It highlights the disparities in resources and opportunities that exist between individuals of different socio-economic backgrounds.

What is the difference between numerical methods and analytical methods?

In analytical analysis we should use related formulas to obtain the analysis results. However many systems possess complex functionality that it is hard to track the system behavior by formulas. in such cases, we should simulate the system and analyze it in some well defined situation to estimate its behavior.

Logic is the study of?

Things clever eg: wisedom, literature - greek , latin , extended subjects

What is an implicit argument in java?

Two implicit arguments are passed into any Java method which is not declared "static". They are referenced using the keywords "this" and "super."

"this" refers to the object instance on which the method was called. For example, in the line of code:

int len = "abcde".length();

Even though String.length() takes no arguments, a reference to a String instance containing "abcde" is passed to length() through the keyword "this." A possible implementation of String.length() could then be:

public int length() {

return this.chars.length;

}

However, in most cases, it is not necessary to explicitly use "this."

The "super" keyword points to the same object as "this" but is instead used to call a member of the object's superclass rather than of the object's concrete class.

What is the object of study of Logic?

The best way to answer this question is that math is the language of science (generally universally recognized as so); but LOGIC is the language of math.

Differences between finite and infinite loop?

A finite loop executes a specific number of times based on its condition, while an infinite loop runs indefinitely without cessation. Finite loops have a predetermined endpoint, while infinite loops continue without a defined stopping condition until manually interrupted. Improperly written infinite loops can lead to system crashes or unresponsive programs.

Advantages of rast method?

The RAST method, or radioallergosorbent test, is advantageous because it is a blood test used to detect specific allergens that may be causing allergic reactions. It is less invasive than skin prick testing and is helpful when a patient cannot discontinue antihistamines prior to testing. RAST can also provide quantitative results, indicating the level of specific IgE antibodies present in the blood.

What is the Javascript onclick?

The Javascript onclick function is a popular part of Javascript. The Javascript onclick function makes it easy and simple for one to quickly link a page.

What is a constructor and its mandatory to use constructor in a class?

A constructor is a method that is invoked when an object is created. As to being mandatory, that really depends on the programming language; in the case of Java, each class must have a constructor, however, in many cases Java will automatically provide a default constructor, so you don't really need to program it.

What is data hidding in oop?

Data hiding in OOP refers to the practice of hiding the internal state of an object from the outside world. This is achieved by encapsulating the data within the object and only allowing access to it through specified methods, known as getters and setters. By hiding the data, we protect it from being modified unintentionally and improve the integrity of the object's internal structure.

Where did the kamikaze's warrior code come from?

Kamikaze is a Japanese word meaning "Divine Wind" referring to an event in the 12th Century. An enormous Mongol invasion fleet set sail for Japan from mainland Asia, but was destroyed in a storm before it could arrive at its destination. The Japanese people of the time believed that this wind was sent by the gods to protect Japan from invasion, hence its divinity.

Towards the end of the second world war, the Japanese military saw that the allies were steadfastly approaching Japan, despite enormous losses. A new unit was formed in the hoped of preventing the invasion of Japan in the same way as the 12th century " Divine Wind" hence the name.

The ethos behind the kamikaze unit, like Japanese militant nationalism in general, was based on a warped form of Bushido. A central tenet of Bushido is putting oneself at the service of one's daimyo or lord or in this case, the emperor. This ideal put duty to one's lord as paramount, even at the cost of one's own life. Dying in battle was seen as glorious, however Bushido does not countenance useless death. An argument could be made that the kamikaze pilots did not die uselessly, as they did in fact slow up the allied advance. However, in the large scheme of things the outcome of the war at that point was never in doubt, it was just a question of time before the allies reached Japan. Bushido in its strictest terms (and maybe this is just my interpretation) would not accept this death as being particularly useful, as it had no real effect on the outcome of the war and this was apparent to the Japanese military leaders at the time they created the kamikaze units. Their view of Bushido was that dying in battle was the important point, in fact the only relevant one. It didn't matter to them that whatever happened, they would lose the war and that they might be more useful to their Emperor alive to help in the postwar reconstruction.

In short:

Japanese militant nationalism exploited a traditional warrior philosophy more suited to a feudal warrior society than an industrial power engaged in total war to produce suicidal pilots whose sacrifice, though courageous, was a futile waste of their lives.

What class is a new servlet usually inherited?

What are the advantages of the new operator?

The new operator in C++ works in a similar manner to malloc in C, allocating memory from the heap (the free store). However, unlike malloc which returns a void* pointer to uninitialised memory, the new operator returns a pointer of the given type and invokes the appropriate constructor for that type. Moreover, every class of object can overload its new operator to allow construction within memory that has been allocated in advance. That memory is typically allocated through a resource handle (known as an allocator), however we can also override the global new operator if we need to provide our own memory management.

We can still use malloc in C++, however it has no advantages over the new operator and is best avoided in the interests of consistency and, more importantly, type safety. In practice we rarely use the new operator unless we are actually designing our own resource handles or low-level memory allocators. The standard library already provides highly efficient resource handles for the vast majority of our everyday needs, so it is rarely necessary to design our own. Nevertheless, the facility exists for those (very) rare occasions where we really do require "raw" memory.

What are the advantages and disadvantages of Norton antivirus?

An advantage is that Norton is a leader in antivirus software and stops most viruses before they have a chance to harm your computer.

A disadvantage is that Norton is costly and free antivirus programs are available that do almost, if not just as well.
