How to Create a Java Program for Division. (With explanations) Java is a common Programming Language used nowadays. In this blog, I will show you how to create a simple Java Program for Division. Java is easy to understand. Java may look difficult but is very easy. If you are having problems in learning it, I have created a tutorial below on how to learn it. Believe me, it is very easy. 1.While writing a division program, you must start with import java.util.*;   Note: don't forget to write ";". It acts as a full stop.   2.Now you need to write "class" and the name of your program. 3.After that, you have to write a command. It is "public static void main()" 4. Next write the scanner class. Just write "Scanner x= new Scanner (System.in);" 5. Next, write "int" and any character such as a,b and c. Int means integer. 6. Now you have to write the output which will be visible to the visitor. So if my characters are a,b,c t

 Explained: What is causing deaths in Covid-19 patients? Hello reader. I am the writer of this blog. I am sorry that I could not post any blog the previous week. So I will publish 2 blogs this week.  Covid-19 is causing worldwide havoc. There has been a rise in the death rate too. But it is not caused by the disease. It is caused by the immune response. Let me explain. Many people with co-morbidities have weak immunity. So, when they get infected with any disease, their immune system starts to panic and overreacts to the disease. This is called Cytokine Storm . So what is a cytokine storm? To understand it, we need to know how our immune system reacts to covid-19 infection. During any infection, the immune system launches an immune response called the innate response. It is a natural response that releases cytokines, an important microscopic protein that acts as an alarm. They generate inflammation. Eventually, it releases a second wave of immune cells. This is called an adaptive respo

          The Sequence of Fibonacci Numbers Fibonacci numbers are a unique type of number. Each number is the sum of the previous two numbers. They start with 0 and 1. Let us find more about them. Fibonacci numbers were invented by Leonardo Fibonacci (1170-1250). As I said before, they are the sum of the preceding two numbers. For ex.- 0,1,1,2,3,5,8,13,21,34. Here 1=0+1, 2=1+1, 3= 1+3 and so on. The diagram will give you some idea about Fibonacci Numbers. Fibonacci Numbers in Nature Fibonacci Numbers can be found in nature too. You can see them in a Sunflower, Seashells, Petals of a Flower, Galaxies and even on our faces!                                                                                                                                                                                This is another example of Fibonacci Numbers in Nature                                     Fibonacci Numbers were also used by Leonardo Da Vinci when he drew Mona Lisa!                           

How Technology and Science is helping in Covid-19 Pandemic The covid-19 Pandemic has wreaked havoc on the whole world. Our lives, both personal and professional have been greatly impacted. During this time of fear and uncertainty, our willingness to adapt to Technology has been our lifeline. Technology is helping us in managing Pandemics Covid-19 has directly impacted close to 1.45 billion students as schools and colleges have shut down. Thanks to Technology ,  most educational institutions have started to offer online courses to make sure that education is not disrupted due to the pandemic. Individuals are inclining toward home conveyance to remain safe. Subsequently, the online market has seen gigantic development.   Online teaching and work from home is a blessing that comes due to technology and is the greatest solution that helps in social distancing. Work from home has ensured business continuity. But just like the sides of a coin, technology has its own minus points.

Explained: Why Green Energy is Important? Nowadays, we have become dependent on fossil fuels and nuclear energy for electricity. However, they cause great harm to the environment. So what is the solution? The solution is green energy. Green energy is a type of energy. It produces energy but does not cause any harm to the environment. Examples include solar energy and wind energy.  So what harm do non-renewable resources cause to the environment? Energy is obtained by burning fossil fuels. Due to which, Greenhouse gases such as Carbon Dioxide (CO2) and Carbon Monoxide are released in the process. These gases build up in the atmosphere and cause pollution. Nuclear Energy is produced using radioactive materials. This can be deadly if not disposed of properly. Green Energy such as Wind, Solar and Water energy does not produce any greenhouse gases. So, they are safer for the environment compared to non-renewable resources. Non- Renewable energy is exhaustible while
