Loops

1. If Else:

When ever you want to perform a set of operations based on a condition If-Else is used.

2. Switch:

Switch is an alternative to If-Else-If ladder and to select one among many blocks of code.

3. For:

For loop is used to iterate a set of statements based on a condition. Usually for loop is preferred when number of ierations is known in advance.

4. While:

While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of ierations is not known in advance.

5. Do-While:

Do-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.

Classes and Objects

Class is the blueprint of an object, which is also referred as user-defined data type with variables and functions. Object is a basic unit in OOP, and is an instance of the class.

How to create a Class:

class keyword is required to create a class.

Example:

How to create a Object:

How to define methods in a class:

Collections

Collection is a group of objects which can be represented as a single unit. Collections are introduced to bring a unified common interface to all the objects.

Collection Framework was introduced since JDK 1.2 which is used to represent and manage Collections and it contains:

1. Interfaces
2. Classes
3. Algorithms

This framework also defines map interfaces and several classes in addition to Collections.

Advantages:

• High performance
• Reduces developer's effort
• Unified architecture which has common methods for all objects.

1. NetBeans – The Best Java IDE Sponsored by Oracle [Freeware]

NetBeans is the best-known IDE for web development. It is an IDE created by developers for developers to make coding as easy and efficient as possible.

Not only does it supports enterprise web applications, but you can also use it to create mobile and desktop apps. And it allows you to reuse your project workspace on multiple platforms like Windows, Linux, Mac OS X, and Solaris from Oracle.

NetBeans addresses most of the challenges a developer might face during the project lifecycle. It will let you manage all tasks starting from analysis, design, coding, debugging, unit testing, code coverage, source code control, and deployment. Moreover, you don’t need any plugin for these features, as all of them are inherent in NetBeans.

Your code might have untracked bugs which are hard to find and can cause delays. But with inbuilt tools like static code analysis, integration of FindBug plugin can help you identify and fix complex issues in the code. Also, the NetBeans debugger gives you a free hand for stepping through the source, set breakpoints, add watches, take snapshots, and track execution.

Moreover, it comes with a powerful code profiler to assist in optimizing your application performance (speed and memory). You can build robust, reliable, and scalable Java and J2EE applications. Next, it also includes a visual debugger for enabling you to debug user interfaces without intervening in the code.

You might not want to miss on Maven, which has got seamless support from NetBeans. Resolving and adding dependencies take just a couple of clicks to complete. It lets you skip from the undesired downloading / rebuilding of indexes.

Let’s check out what else makes NetBeans tops the Java IDE list.

It has excellent support for HTML5, CSS3, JavaScript (ES 5/6), and Angular JS. And not only does it shows code suggestions, hints but also support auto-completion for these languages along with Angular directives.

NetBeans enables mobile app development with the help of frameworks like Cordova and PhoneGap. And it’s a joy to create mobile apps using these frameworks in NetBeans.

Also, with GlassFish and WebLogic, it’s easy to deploy any web app and test the end to end functionality. It infuses Java 8 support at the core and enables code suggestions to switch for-loops into Java 8 streams and lambdas.

NetBeans supports all popular Web application frameworks (Spring/Struts/Wicket) and libraries like PrimeFaces, RichFaces, ICEfaces.

2. IntelliJ IDEA – The Best IDE for Java Developers [Paid Java IDE]

IntelliJ IDEA is a slick, fast, and reliable tool for web development in Java. It is none other than the featured tools development company called JetBrains, who runs this product and update it for the growing market needs.

The company delivers it in two forms: Free community version and the Paid ultimate edition. The free version is to encourage students, teachers, and plugin developers, whereas the paid version is for organizations developing commercial applications.

IntelliJ Community Edition

The free edition enables support for frameworks like Android, Swing, and JavaFX. It is also versatile in supporting programming languages like Java, Groovy, Kotlin, Scala, Go, Dart, Erlang, and Python.

Also, the IDE is lightweight. It brings a few other features like JUnit/TestNG test runners, debugging, code completion, code inspections, code refactoring, maven wizard, Ant, and a visual GUI builder.

You can even enjoy four types of version control systems, which include Git/GitHub, SVN, Mercurial, and CVS. And there is a Docker plugin to support the deployment of web apps. The free version also incorporates a Decompiler and a ByteCode viewer to perform Deep Analysis.

IntelliJ Ultimate Edition

For beginners, the free version has ample features to start web development in Java. More advanced users should prefer the ultimate edition to unlock all available options.

It’s a premium IDE which supports many leading programming and scripting languages, e.g., JavaScript, TypeScript, SQL, CSS, LESS, Sass, Stylus, CoffeeScript, ActionScript, Ruby, and PHP.

For world-class web development, you need Ultimate version as it integrates frameworks like Spring MVC, J2EE (JSF/JAX-RS/CDI/JPA), Grails, Griffin, React, Angular JS, Node.js, Django, Flask, CMS (Drupal/WordPress/Laravel).

It has additional version control support, e.g., TFS, Perforce, ClearCase, and Visual SourceSafe. Also, there are plenty of options to customize your deployment strategy using Tomcat, TomEE, GAE, GlassFish, JBoss, WebLogic, WebSphere, Geronimo, Jetty, and Virgo.

To ramp up your builds, it has NPM, WebPack, Gulp, and Grunt support. And it adds tools like Diagrams (UML/Dependencies), Dependency Structure Matrix to improve quality.

3. Eclipse – The Illustrious IDE for Java Developers [Freeware]

Eclipse is a new age, cross-platform, open-source, and freely distributed IDE available for enterprise web development.

Android Studio is a modern IDE for out of the box Java and Android application development. It is relatively a new product which got released in the mid of 2013. Derived from IntelliJ IDEA, Android Studio delivers the optimum turnaround on your design and code workflow.

The idea behind this tool was to accelerate the development process and help you create high-quality apps for any Android device. Also, when it wasn’t around, the developers had to rely on Eclipse and ADT plugin. Because of this, the Android OS was falling behind competitors like Apple. And after Android Studio, Google saw a steep rise in Android popularity and apps usage.

Android Studio bundles a whole list of features that include intelligent code editing, debugging, unit testing, and code profiling. Let us look at each of them in a little more detail.
