java programming solutions

A Java virtual machine is software that runs on non-virtual hardware and standard operating systems. A JVM provides an environment that can run Java bytecode, allowing functions such as automated exception handling, which provides the "root causes" of the debugging information for all software errors (exceptions), independent the source code. A JVM is supplied with a set of class libraries that implement the standard Java application programming interface (API). API grouped with Java Runtime Environment (JRE).

JVM is available for many hardware and software platforms. Using the same bytecode for all JVMs on all platforms allows Java is described as a "write once, run anywhere" programming language, instead of "write once, compile anywhere", which describes multi-platform compiled languages. Therefore, the JVM is a crucial component of the Java platform.

Java bytecode is an intermediate language, which is usually based on Java, but it can also be collected from other programming languages. For example, Ada source code is compiled into Java bytecode and run on a JVM.

Oracle, the owner of Java, the JVM to produce, but the JVM with the name "Java" must be developed by other companies, provided they meet the specific JVM, published by Oracle, and its contractual obligations and the best programming solutions ever.

java importance online tutoring

The Java programming language developed by Sun Microsystems. This is a programming language object-oriented. It is one of the best programming languages ​​networked computers.

The growing trend for the BlackBerry, in telecommunications, is also supported by the Java platform. Applications of these smartphones are developed using Java as a programming language.

Java is a very secure, robust, multi-threaded, dynamic language that gives the freedom to run applications on any operating system.

The Java programming language was developed and re-designed for use on the Internet. In the area of ​​Internet, Java's popularity has increased dramatically, especially in the server side of Internet. Today, there are a large number of Java experts, who struggle to improve and strengthen the development of Java. For beginners who are interested in learning Java, there are of course many Java training available online. You can see a line of Java programming course using a profit of instructor-led training or self learning. However, it is much better to participate in an online course instructor training.

Do not get confused between Java and Javascript. JavaScript is a scripting language which shares a similar name, and has the same syntax, but is in no way related to the basic language of Java. Javascript training courses focus on web design.

To learn Java, several books are available in the market and online. Not everyone can learn Java through self-learning (reading books / study materials, etc.) This is why there is a strong market for teacher training to adults. You can join a Java programming course to improve your programming skills and take the ladder of professional success.

Dependable IT Programming Solutions is a young and dynamic organization of courses in London Java. Academic institutions around the world provide basic and conceptual grounds cover several areas of computer science. But credible IT solutions through training of Java, it allows full in-depth understanding of commands and concepts used in the development of professional and advanced applications in Java.

Paper Gold assignment help

The post-war international monetary system may be characterized as the ‘currency reserve standard’, wherein the U.S. dollar has been serving as reserve asset as good as gold, at least, till the fifties. But, due to the shaky position of U.S. dollar, and for other reasons such as speculation in gold, chaos in Euro-dollar market etc., this system faced acute problems of international liquidity like balance of payments difficulties, inadequate growth of monetary reserve and fragility of gold exchange standard.


Economists have visualized three aspects: liquidity, adjustment and confidence in the problems of international liquidity. To solve these problems a reform in the existing international monetary system was regarded inevitable. Many proposal and plans have been suggested to evolve some alternative system to get rid of the difficulties faced by the existing system.


Eventually, a proposal aimed at limiting the future role of dollar and sterling and broadening the functions of the IMF has been put forward. It is called the scheme of Special Drawing Rights (SDRs) commonly held as ‘Paper Gold’. It was approved in principle at the Fund’s annual meeting at Rio de Janeiro in September1967. The SDRs scheme was, however, come into operation only since January 1970.


Under this scheme the IMF is empowered to grant member governments special drawing rights (SDRs) on a specified basis, subject to ratification. SDRs are regarded as the international reserve allocated annually by the collective decision of participating members in the fund. Possession of SDRs entitles a country to obtain a defined equivalent of currency form other participating countries and enable it to discharge certain obligations towards the general account of the fund. The creation overcome their temporary foreign exchange difficulties without putting any additional strain on the IMF resources SDRs are thus method of supplementing the existing reserve assets in international liquidity.


A precise mechanism has been evolved in the implementation of the SDRs scheme. Under this scheme a country (say country I) needing convertible foreign exchange resources had to apply to the fund for the use of SDRs. It can use its special drawing rights up to the limit of allocated amount. On receiving such an application the fund would designate another country (say country II), whose balance of payments and gross reserve position are sufficient strong called the designated country to meet the foreign exchange needs of country I. Then, country I can draw on the designated country at the most upto a total net amount equal to twice the amount of SDRs allotted to the designated country. To illustrate the point suppose country I has been allotted an SDRs quota of 1,000 units and the designated country (country II) has been allotted a quota of 1500 units, now if country I seeks convertible foreign exchange of 500 units for which country II has been and given them to country II in exchange for an equivalent amount of convertible foreign exchange programming solutions and country I thus becomes a debtor and country II a creditor country. The debtor country has to pay interest at 1.5 per cent per annum of the units surrendered to the creditor country.


It must be noted that the designated country cannot be asked to provide foreign exchange for the SDRunits in excess of twice the quote of SDRs allotted to it 1500 × 2 = 3,000 units in our illustration). In case the requirements of a country exceed twice the amount allotted to the designated country some other countries along with this country will have to be designated to meet the total requirements.

best online math help

If a curve is arbitrarily close to an infinite segment of a line L, then L is called an asymptote of the curve. Equivalently, we give the following math homework help solution :

Definition: The line y = mx + c (m ≠ 0) is called an asymptote of a curve y = ƒ(x) if the perpendicular distance of any point P(x, y) on the curve from the line approaches zero as x  ∞ + or - ∞.

We shall now determine the conditions in order that the line

y = mx + c

is an asymptote of the curve y = ƒ(x). If p denotes the perpendicular distance of any point P(x, y) on the curve from the line, then



By definition p0 as x  ± ∞

 limx ± ∞ (y – mx – c) = 0                                                               (i)



Since otherwise the limit in (ii) would be



This determines the value of m. Now, by (i), we have

c = m limx ± ∞ (y – mx)                                                                       (iv)

This determines the value of c.

Rule: The line y = mx + c (m ≠ 0) is an asymptote of the curve y = ƒ(x), where m and c are determined by

m limx ± ∞ y/x ,c = limx ± ∞ (y – mx).

Tangents at the Origin math homework help

Let the equation of the curve passing through the origin be

(a1x + a2y) + (b1x2 + b2xy + b3y2) + …. + (l1xn + … + lnyn) = 0                  (1)

Let P (x, y) be any point on the curve. The slope of the chord OP is  . Thus the equation of the chord OPis

Y = .

As x0, the chord OP becomes the tangent at O and so the equation of the tangent at O is





Y = mX, where m = limx0 .             (2)

Dividing (1) by x, we obtain



Taking the limit as x0 and using (2), we obtain

a1 + a2m = 0

i.e. a1 + a2 Y/X = 0           (∵ Y = mX)

i.e. a1X + a2Y = 0.

Thus the equation of the tangent at the origin may be taken as

a1x + a2y = 0.

This equation is same as the lowest degree terms in (1) when equated to zero.

If a1 = a2 = 0, then (1) becomes

(b1x + b2xy + b3y2) + (c1x3 + c2x2y + c3xy2 + c4y3) + …. = 0           (3)

Dividing the x2 and taking the limit as x0, we obtain

b1 + b2m + b3m2 = 0

Or, b1 +  = 0          (∵ Y = mX)

Or, b1X2 + b2XY + b3Y2 = 0.

We may write it as

b1 x2 + b2xy + b3y2 = 0.                               (4)

which represents a pair of tangents at this origin.

The equation (4) is same as the lowest degree terms in (3) when equated to zero.

Similarly, it can be shown that if a1 = a2 = 0 and b1 = b2 = b3 = 0, then c1x3 + c2x2y + c3xy2 + c4y3 = 0is the equation of the tangent at the origin. Hence we have the following:

Rule: The tangents at the origin are given by equating to zero the lowest degree terms in the equation of the given curve according to the math homework help experts
