Major Differences between C, C++ and Java

There are 3 languages that are ruling the world of programming. They are C, C++, and Java. These languages are building blocks of many programming languages. In this blog we will discuss them in brief and will see how they differ from one another.

Introduction to C

C, developed in 1972 especially for unix operating system is a high level language. It was developed after B language which came in 1970. It is widely used language now-a-days as it is easy to learn and also can be compiled on wide range of computers. Not only this, efficient and versatile programs are build using this.

Introduction to C++

Super set of C is C++. It is also a general purpose language. It is complied but life of serious programmers. It is flexible than C, this makes it more efficient. The X-factor in C++ is the concept of class. These are the user defined type. Many C++ institutes offer advance courses in it as it is the need of very IT industry.

Introduction to Java

Developed in 1991 but was available to public in 1995. It is owned by Oracle Corporation. It is object based language. Its syntax is similar to C and C++. The latest working version of Java is 13 which came in 2019 only. There are now so many core java training institute in Delhi which can help you be pro in the field.

Now, Lets see,

How C, C++ and Java Differ from Eachother :

1. Different Paradigms
The main difference between the 3 of these lies with the different programming paradigms that they use. C is a procedural language whereas C++ and Java are Object Oriented.

2. Range of Keywords
They have different range of keywords. C has 32, C++ has 63 whereas Java has 50 defined keywords.

3. Supporting Header Files
C and C++ both support header files whereas Java does not support header files, it uses packages, where packages are imported into java platform.

4. Criteria of Inheritance
Inheritance is considered as an important aspect of programming language. There are two types of inheritance, single as well as multiple. Single inheritance is supported by C as well as Java. But C also supports Multiple Inheritance unlike Java. Whereas no such criterion is supported by C++.

5. Different Kinds of Storage Allocators
All three uses different types of storage allocators. C uses malloc and calloc function library for dynamic allocation. C++ uses new and delete function Whereas Java uses garbage collector for the same purpose.

6. Constructor and Destructor Class
Constructor is a class which initialises each and every project whereas Destructor takes part on destroying that class. Neither C nor Java supports this. whereas it is supported by C++.

7. Use of Multithread and Interfaces
When two or more parts of a programs are executed consequently at that time CPU is utilized at its maximum this is called multithreading and each part of such programs is known as thread. This feature is only supported by java and not the other two.

8. Use of different types of approach
C uses a Top-Down approach whereas Java, as well as C++, use Bottom-Up approach. These approaches are used to gather the knowledge and processing of a program.

9. Language Translators Used
C and C++ use compiler only as a language translator whereas Java needs both compliers as well as an interpreter for interpretation of language.

10. Code Execution Machine
Execution of code is done directly in C as well as C++ unlike Java where code is not executed directly and requires proper JVM i.e. Java Virtual Machine to execute the code.

Conclusion

I hope now you must have understood the main differences that distinguish the three most wanted programming languages in the field of IT industry. You can start of your journey with the basic i.e. C by joining C courses in Rohini and then after learning this can go for C++ as well Java. ADMEC Multimedia Institute is considered as the best C++ institute as well as core java institute in Delhi.

10 Not to Avoid Points while Learning Java

If we talk about object orientation, it includes Java one of the best object-oriented languages which is used for mobile and web applications and which is developed by Sun Microsystems. It is a platform independent language because it can be run on different platforms like Mac, Windows, Linux etc. Here are some important points which one shouldn’t avoid while learning Java course in Delhi

Important Points of Java 

1. Java is not a Multiple Inheritance Language

It does not support multiple inheritance which means one class cannot inherit multiple classes but it supports hierarchical inheritance which means one class can have two extended child classes.

2. Overriding in Java

It means that Java is providing the ability to child class by different implementations of the superclass. When subclass has the same parameters, same name and same return type of its superclass then it called as overriding. Overriding can be known as Run Time Polymorphism. 

Know Some Rules for Method Overriding? 

1) Access modifiers must be used in priority fashion which means if a class is protected then it cannot be private it only can be public in override.
2) The final methods in Method Overriding cannot be done it shows an error.
3) The static method can only be used to hide if and only if the supper class and subclass both methods are static.
4) Overriding of private methods cannot be done because of restrictions during the compilation time. 

3. Method Overloading

Which means having the same name as the method but different parameters, this can be achieved by changing the number of arguments and changing the data type of the arguments.
It helps with the enhancement of the readability of the program.
Java main method can also overload the.

4. Abstraction 

Abstraction in Java it uses to hide the delicate functionalities of the program and only show the important things to the user.
For example, when we send the SMS we only know the text in SMS and we don't know the functionality of sending SMS.
Abstract Classes cannot be instantiated, it only can be extended or method implemented.

5. Java Packages

These are of two types one is user define and build in packages.
Swing, net, io, util, SQL,  util, lang, awt,  javax etc. are some Java Build-in packages. It is helpful because it avoids naming collisions, provides protections. Java Packages and interfaces are used to categorized classes in Java.

Know the Running Process of Java packages? 

To compile use –  javac -d. filename.java
To Run the Java program using- Java package_name.filename
Here, javac command use for compiling the Java file, -d it tells to Java compiler where to place the class files.
There are three ways to import the Java packages from outside of the classes-
1) import package.*
2) import package_name.classname
3) fully qualified name
The standard way to define the Package Name must be- domain.company.package

6. Bindings in Java

In Java, method body and calls can be interconnected and that is known as Bindings of Java.
There are two types of Binding like-
1) Static
2) Dynamic
Static Binding- In Java, Static binding is also known as Early Binding. If any methods have static, private, final.
When the type of Object is determined by the compiler then it is known as binding in static.
Dynamic Bindings- When the type of an object determines at runtime.

7. The instance of operator

It is a type of operator which use to compare that a specific object is of which type and after comparing that it returns true or false.

8. Java Swing 

These are light-weighted and platform-independent components. Swing is a part of Java Foundation Classes (JFC) which is used to create window-based applications.

9. Java Applet 

Useful at the client side because it uses to create dynamic content on web pages.It has various advantages like consuming less response time as it is a server-side language.There are two ways to run an applet i.e. by the use of HTML file and second is AppletViewer which also use for testing purpose. It uses in Gaming and animations mostly.

10. JDBC

Java is used to connect and execute a query on databases which is a Java API. It uses JDBC drivers to build connections with databases.

History of JDBC

Before the JDBC, ODBC API used with the database which uses ODBC drivers. ODBC has written in C language which is not secure and platform dependent so, for JDBC has developed its own API which uses its own drivers which are written in Java language. JDBC is used to handle the database activities and perform various activities like Connect, Execute and Retrieve.
Java is a language which is based on Object orientations, which is platform independent and widely used. Java uses inheritance, Overriding, Overloading, Abstraction, Packages, Binding in Java and some more important like Instance of the operator, Java Swing and JDBC. 
So, you need to grasp all the essential perceptions and fundamentals of Java very profoundly and for accomplishing such type of in-depth learning joining finest Java Training Institute in Delhi is decidedly recommended.
