Answer 1

**What is Java?**

Java is a general-purpose programming language, which is released by Sun Microsystem in 1995. It is a computing platform for application development ex. web application, mobile application, etc.

**What is C?**

C is a procedural or general purpose programming language, which is design by Dennis Ritchie in 1972.

C is older than Java.

Java Hello World Example

1. public class Hello{
2. public static void main(String[] args){
3. System.out.println("Hello, World");
4. }
5. }

C Hello World Example

1. #include <studio.n>
2. int main(int argc, char ** argv)
3. {
4. printf("Hello World!\n");
5. }

Features of Java-

Java offers many features, which make it a King of All Programming Language-

1. Java is Simple
2. It is Object-oriented language
3. Java is widely used because of its security feature.
4. Java runs of JVM, means It supports WORA (Write once, run anywhere)

On the other hand, the features of C tells how C becomes a mother of all programming languages-

1. C programming offers you a structured oriented feature. Which will divide your code and task with a function.
2. C is a simple and easy programming language, which provide a structured approach to solve your queries in parts.
3. It allows the user to allocate the memory at the run time.
4. With the help of dynamic memory management, you can manually decide the memory requirements of your program at the run time.
5. Pointers in C helps to store the memory address as its value.

Approaches-

C follows a top-down approach, means flow of program are important than data on which it operates.

Another way out, Java follows a bottom-up approach.

Object Management-

In C, object management is done manually.

Java has a garbage collector, which is automatically managed.

Threads -

C doesn’t support threads, on the other hand, Java is vice-versa.

Overloading

Java supports overloading for code readability, but C not.

Applications of Java and C in real-world

Java has many real-time use cases, but it is mainly used to develop applications,

1. Desktop application
2. Web application
3. Desktop application
4. Mobile application
5. Enterprise Application
6. Scientific Application
7. Real-time software
8. Smart Cards
9. Cryptography
10. Computer Games etc

y**

From the above graph (15/04/2019 - Google trends), we can say C is less popular than Java. People around the world, like to search, explore and read about Java, not C programming language.

Now, let’s talk about there offering, means features.

There are many positive impact of Mobile Computing,as the growing adoption of smart mobile devices, such as smart phones and tablets, is fundamentally changing the way how business is conducted. New mobile technologies exert a significant influence on individuals, organizations, and society at large.
      It significantly impact how we deliver educational content, how we interact with our students and each other, and even how our students learn.
     The growth and maturation of mobile computing is about much more than just the next generation of cell phones or tablet computers. It's about merging communication mediums with the vast capabilities of the Internet and combining them into a portable, powerful, intuitive device that can play a valuable role in assisting, and even improving, many aspects of our daily lives.Mobile devices have emerged as viable and effective programming platforms. At the same time, cloud platforms have been established as viable platforms for applications and data. The introduction of the mobile devices have introduced new programming languages that allow for rapid and efficient programming that will eventually make traditional programming obsolete.

Java has been impacted by the emergence of mobility as well. This marks a significant shift as Java languages have been on a steep decline over the past 10 years. As the mobile movement began to gain major steam, the Java programming structure begin to regain its footing. This began approximately two years ago and the growth has been steady.

As mobile programming builds momentum, it will consistently bring developers to a lower position or level of programming, one that is much more closely connected to the hardware. The traditional scripting languages used in programming don’t have the same traction with mobile devices. This is because the scripting code used in mobile devices is smaller and more specific in order to facilitate all of the new hardware features that a specific device may offer. For the first time ever, all scripting languages, including Python, PHP, Perl and Ruby, have declined over the previous year.

The experts are predicting that the decline in the use of scripting language in lieu of more native languages will continue. In fact it can be seen clearly in the .NET world. There was a massive increase in the use of C#, which was second only to Objective-C’s as far as a spike in usage is concerned. There is no doubt that the emergence of mobile devices will continue to reshape the programming world for years to come.
