Java language has some unique features than others. Following is the major difference between java and all other popular languages.
Difference between C, C++ and Java clearly specifies that how java programming language is better than others.
There are several new things added in java language and also removed from java to make it better to code.
| No | C | C++ | Java |
|---|---|---|---|
| 1 | C is procedure oriented language. | It is C with object oriented extension | It is true object oriented language |
| 2 | C supports the user defined data types like struct and Enum | C++ supports the user defined data types like struct and Enum | Java doesn’t support struct and enum |
| 3 | C supports the type modifier keywords auto, extern, register, signed,unsigned | C++ supports the type modifier keywords auto, extern, register, signed,unsigned | Java doesn’t support the type modifier keywords |
| 4 | C supports the pre-processors | C++ supports the pre-processors | Java doesn’t support pre-processors |
| 5 | C supports pointer | C++ supports pointer | Java doesn’t support pointers |
| 6 | C doesn’t do memory management automatically. | C++ doesn’t do memory management automatically. | Java does the memory management automatically |
| 7 | C supports header files | C++ supports header files | Java doesn’t support header files. |
| 8 | C supports the global variables | C++ supports the global variables | Java doesn’t support global variables |
| 9 | C is platform dependent | C++ is platform dependent | Java is platform independent |
| 10 | C program is not secure | C++ program is secure than c language due to oop | Java program is very much secure than C and C++ |
Python is a widely used general-purpose, high-level programming language. following difference determines the difference between Python language and Java programming language
| NO | Python | Java |
|---|---|---|
| 1 | Python doesn’t require the setup for programming. | java requires substantial amount of setup |
| 2 | Python uses indentation to separate code into blocks. | Java uses curly braces to define beginning and end of function and class. |
| 3 | Python uses dynamic typing, which allows us to change the type of variable | Java need to define type of variable and doesn’t allows us to change the type of variable. |
| 4 | Python requires a compiler to turn python code into particular Operating system | Java can run on any computer to mobile device by using JVM to run java applications |
| 5 | Python is easier language for beginner programmers. | Java is powerful language |
| 6 | Python requires very less time to write the code. | Java requires more time to write the code. |
| 7 | In Python Object oriented programming is optional | In java Object oriented programming must be followed |
Javascript language is different than java language. both have used for different purposes as shown below. difference between java and javascript
| NO. | Java | JavaScript |
|---|---|---|
| 1 | Java is a computer programing language which is class based, and object oriented. | Javascript is an interpreted computer programming language. |
| 2 | Java is designed to run on virtual machine | Javascript is designed to run on web-browsers |
| 3 | Java need compile the source code into bytecode for machine understanding. | Javascript does not need to compile the code, it can run directly. |
| 4 | Java code is larger than the javascript code | Javascript contains much simpler and smaller code. |
| 5 | Java language need to setup the environment or software before starting the programming. | Javascript needs only the text-editor and web-browser to start programming. |
| 6 | Java needs to write everything inside the class. Called class based | In javascript there is no concept of class. We can write inside the function/object. Called prototype based. |
| 7 | Java uses static type checking means all error are caught while compiling the program before running. | Javascript uses dynamic type checking means it checks the code while running/executing. |
| 8 | In java we cannot directly access all properties of another class by inhering other classes. | In javascript every object can inherit directly from its ancestor object. |
| 9 | Java is best language for server side development. | Javascript is best language for client side development. |
| 10 | Java language is developed by sun microsystem later owned by oracle corporation. | Javascript is developed by Netscape communication corporation. |
