Java Vs Python

Java

Java is a computer programming language, most popularly used in the development of Android smartphone applications. It was first released by James Gosling at Sun Microsystems in the year 1995 and later acquired by Oracle Corporation. It is the most fundamental language that produces software for multiple programs. Initially, it was designed to have a feel of C++ but later with its multiple use and extra benefits, it became much simpler and popular than C++.

If you follow the basic definition, Java is a general-purpose computer programming language that is class-based object-oriented and concurrent in use. Meaning, with the use of Java you can execute many statements at the same time instead of sequentially executing it. Using Java, computation can be advanced without waiting for all the other computations to complete. It is also an independent programming language following the logic of “Write once, Run anywhere” i.e. the compiled Java code can run on all the platforms that support Java without the need for recompilation Python.

Python, on the other hand, is another great general-purpose programming language used for a variety of wide applications. Python’s high-level built-in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development. This feature of Python makes you construct and enable clear programming on both the simple as well as the most complex applications and website. With no lot of syntax and easy readability quality, Python code is much easier than the other programming languages. Which on the subsidiary makes its maintenance and development cost of programming very less.

Python code of programming supports all the use of modules and packages. This feature of Python give its program the vulnerability to design in modular style and can be reused across a variety of projects. Being an interpreted language unlike other programming languages its written code does not get translated in the computer-readable format at runtime.

Conclusion

Thus after going through the above conversation, we can say, both Java and Python are rich programming languages. According to the need of your application, choose the language you find best features with for your desired application. Compare the features of both Java and Python from above accordingly to choose the best programming language for your application.

Collections Class in Java

Content writer: Suman Chauhan

Collections in Java

A Collection in simple terms means when a group of similar things, often a group created by someone is known as a collection. A collection when collected works like a container – it groups multiple similar elements into a single unit. Forming a natural group they can be stored, modify, redeem, recover and communicate aggregate data.

Java provides a collection framework defining several groups and interfaces to represent groups of objects as a single unit. Collection framework is one of the central and fundamental parts of Java programming language.

What Is Collection In Java

Collection in Java represents a single unit of the group. Using Java collection you can perform all the operations on the data like searching, sorting, inserting, manipulation, deletion, etc.

What is a framework in Java

A framework or software framework is the platform used for developing software applications. They are the large collected bodies of prewritten codes to which you add your own code in specific domains. It helps you dictate the structure of your application, by calling its methods, and inheritance.

Framework specializes classes to invoke the single method or procedures. It employs an inverted flow of control between itself and its clients. Using framework one can implement the call back functions, specialized classes, and interfaces.

What Is Collection Framework?

Java collection framework provides you with the complete architecture of objects. Java frameworks group of objects includes  – classes, interfaces, and algorithm.

Class – Everything in Java is associated with classes and objects. Being a user-defined blueprint, a class in simple terms represents the data structure which is used again and again. It helps in creating objects. A class represents the common attributes and properties to the objects of one type.

Interface – Interface is the blueprint of class, specifying what a class should do. The interface in Java refers to an abstract “class” that is used to group related methods with “empty” bodies.

Algorithm – Algorithm refers to the process and the set of rules used to perform the operations such as searching and sorting.

Methods Of Collection Interface

Before learning about the methods of collection interface, you should first know what Collection Interface means. Collection Interface defines the most common methods that are applicable to any collection of the object.

There come various methods of Collection Interface, which are:

Iterator Interface in Java

Iterators are one of the predefined interfaces that are present in the java.util.*package. Iterator Interface’ main purpose is to provide the facility of iterating or extracting the elements of the collection in the only forward direction.

It Java collection it takes the place of Enumerations. By default, an object of the iterator is pointed out just before the first collection of any framework collection variable.

Methods of Iterator Interface

Public boolean hasNext()

This method returns the true value if iteration has more elements in it, otherwise, false.

Public object next()

It helps you retrieve the next element of any collection framework.

remove()

This method helps you remove the last element returned by the iterator.

List Interface

It is a child interface of Collection, possessing an index-based method to insert and delete elements in it. It is helpful in declaring the behavior of a collection which stores a sequence of elements.

In its ordered collection of objects, it can store the duplicate values. List Interface is implemented by Array List, Linked List, Vector and Stack classes.

Java ArrayList

Array List being a part of collection framework helps you provide dynamic arrays in Java. It is slower than the other standard arrays but is very helpful in programs, where lots of manipulation in the array is required.

As the Java ArrayList class is non-synchronized, it is helpful in maintaining the insertion order.

Java LinkedList

LinkedList is way too different than the ArrayLists. Their structure of elements is not stored in contiguous locations. Each element of LinkedList is a separate object with a data part and address part. Due to this quality, they are preferred more than the Arrays.

Java LinkedList class is used as a list, stack or queue. However, Java LinkedList manipulation is fast because it requires no shifting needs.
