As a budding programmer what would you consider are the best qualities of a programming language? From cutting costs to shortening the execution time Java has got it all covered.

This is why web developers consider Java one of the most robust and innovative programming languages. When we talk about the different concepts incorporated in this programming language you will certainly find each and every one fascinating.

So is the Fibonacci sequence in Java. It was named after an Italian mathematician who went by a similar name. According to this sequence, every consecutive term in a series is the sum of the first two characters.

Learn more about the Fibonacci series in Java and the concept of Multiple inheritances in Java in this blog.

What is the Fibonacci series?

The Fibonacci series in Java always starts with the numerical 0. The main characteristic of the Fibonacci series is that every third number of the series will be a sum of first two.

For instance, let us take the example of the following ...
... Fibonacci series:

0 1 1 2 3 5…

Here in the above example, you can observe that starting with the numerical 0, every third number in the series is the sum of the first two digits.

This is how the series progresses to a certain level according to the sum or the problem that you will be asked to solve related to the Fibonacci series.

How to print a Fibonacci series?

So far we have discussed how the series progresses in relation to Java. Now we will take an example and discuss how you can print the Fibonacci series in Java.

Example

Let us consider that the two given levels i.e 0 and 1 are equal to x and y respectively for this example. We have considered 0 and 1 as the first two levels because a Fibonacci series always starts with the level or number 0.

We will also consider a z static value for storing the number 0, this is because while calculating the sum in a Fibonacci series we always start with the first digit which in this case is 0.

Finally, we have to treat the maximum value in the series as n, this is the number till which we will be printing the Fibonacci series.

This is what is the objective of the question. We will have to figure out the value of n.

By running the value of n you will be able to determine the solution to the given problem.

Interesting characteristics of the Fibonacci series

=> Continuation till infinity

Due to the property of the series, it has the potential to continue till infinity. Although this is something which is not usually common or used in practice.
The series may continue till infinite digits because you can find the sum of the last two digits in a Fibonacci sequence till the level you are aiming to acquire.

=> Golden ratio

The series is often associated with the Golden ratio of 1:1:6 which is observed in numerous suits of nature. This ratio is commonly used in web interfaces, architecture, and other endeavors throughout the world.

=> Observed in biology

You would be stunned to know just about the number of applications the Fibonacci sequence has in the natural works of biology. This is why this sequence is being studied by both physicists and biologists.
The Fibonacci series is present in the patterns of the leaves which is quite intriguing. Sometimes this sequence is also considered to be in a spiral form.

We have discussed this time and again through our blogs that Java is undisputed when it comes to programming languages. There are innumerable concepts to learn in Java and all of them have the potential to grab your attention.

We will now move towards another topic of discussion for this blog i.e Multiple inheritances in Java.

Multiple Inheritance in Java

Multiple inheritances are the concept where the compiler decides to inherit more than one class while running the program.

This concept works well on paper but at the time of execution, it is not practical in Java. This is because two parent classes or even subclasses can share the same exact signatures.

This will only confuse the compiler to make a decision between two classes that share the same features. This makes the concept impractical in the context of Java.

Let us understand this concept with an example.

Example

Assume that there is a class x that has decided to proceed with class y and class z. Now, the classes y and z share a similar method display().

This means that class x has to make a decision to proceed with either one of the classes. In this case, since both the classes share the same logic, it is not reasonable for class x to decide between the two.

This makes the whole concept of multiple inheritances in Java null-and-void.

Hope that clears out the reason why Java cannot support the feature of multiple inheritances in the compilers.

Winding Up

The key point to note in this blog is that the Fibonacci sequence is encrypted in the laws of nature as well. It is not only used in the context of computer science and physics but is also prevalent in the studies of biology and architecture.

If you would like to know more about the Fibonacci series in Java and how to print it using the programming language, you will be able to find it in the first section of this blog.

Other than that we have also explained the concept of multiple inheritances in Java at length and cleared out why it is not applicable in Java.
