How to open idea injelliJ from command line

Hi Friends,

It becomes very handy to open project in your IDE without wasting time in navigation from UI. To accomplish the same here is simple way. Run below commands and you are done 😉

curl -L "" -o /usr/local/bin/idea
chmod +x /usr/local/bin/idea

usage: open terminal and navigate to your project

idea .

Tested on Mac OS X

Note: If you get a “Permission denied” error, your /usr/local/bin directory probably isn’t writable and you’ll need to install script as the superuser. Run sudo -i, then the two commands above, then exit.

IDE : Brackets–A Javascript light weight editor

No need to refresh page, the html changes will reflect at the run time.

A modern, open source text editor that understands web design

Brackets is a lightweight, yet powerful, modern text editor. We blend visual tools into the editor so you get the right amount of help when you want it. With new features and extensions released every 3-4 weeks, it’s like getting presents all year long.

IDEs on web or online playground for JS

A variety of code playgrounds have appeared during the past couple of years. The majority offer a quick and dirty way to experiment with client-side code and share with others. Typical features include:

  • color-coded HTML, CSS and JavaScript editors
  • a preview window — many update on the fly without a refresh
  • HTML pre-processors such as HAML
  • LESS, SASS and Stylus CSS pre-processing
  • inclusion of popular JavaScript libraries
  • developer consoles and code validation tools
  • sharing via a short URL
  • embedding demonstrations in other pages
  • code forking
  • zero cost (or payment for premium services only)
  • showing off your coding skills to the world!

The best feature: they allow you to test and keep experimental snippets code without the rigmarole of creating files, firing up your IDE or setting up a local server.

My favorite is Plunkr.
Plunker is an online community for creating, collaborating on and sharing your web development ideas. It has a very good support for AngualarJs.

It is just like an IDE on web. You can make changes in file see the preview online, error notification etc. Best thing is you can share the final POC with others to experiment Smile you can create multiple files in the same project. This means you can test more abstractly, and easily swap functionality in and out. Your HTML head is in your code window making it easy to see what’s getting loaded. Being able to create your own files also means being able to create external datasources, which is fantastic for playing with dataloading functionality.


However there are other and they are nice as well. Have a look at them and pick what suits your taste Winking smile


JSFiddle was one of the earliest code playgrounds and a major influence for all which followed. Despite the name, it can be used for any combination of HTML, CSS and JavaScript testing. It’s looking a little basic today, but still offers advanced functionality such as Ajax simulation.


The prize for the best-looking feature-packed playground goes to CodePen. The service highlights popular demonstrations (“Pens”) and offers advanced functionality such as sharing and embedding. The PRO service provides cross-browser testing, pair-programming and teaching options for just $9 per month.

CSS Deck

This may be named CSS Deck, but it’s a fully-fledged HTML, CSS and JavaScript playground with social and collaboration features. It’s similar to CodePen (I don’t know who influenced who!) but you might prefer it.

JS Bin

JS Bin was started by JS guru Remy Sharp. It concentrates on the basics and handles them exceedingly well. As far as I’m aware, it’s also the only option which offers a JavaScript console. Recommended.


Another early playground, Dabblet started life as an HTML5/CSS3 demonstration system by Lea Verou but it’s recently received JavaScript facilities. It looks gorgeous and has one killer feature — browser CSS prefixes are added automatically. There’s no need to enter that -webkit, -moz and -ms nonsense yourself.


Tinkerbin is an alpha release and one of the simpler options here. It may not offer features above and beyond the alternatives but it’s attractive and functional.


Liveweave is slightly unusual in that it places your HTML, CSS and JavaScript into a single file. It’s not possible to share your creation, but you can download the result and store or open it locally. It’s ideal for quick and dirty private experimentation.

How to Find Which classes implements a particular interface by Eclipse?

Simplest way:

Right-click on the interface, and choose “Open type hierarchy”. Then click on “Show the subtype hierarchy”.

Another way:

  • In the interface, move the cursor to the method name. Press F4. => Type Hierarchy view appears
  • In the lower part of the view, the method should already be selected. In its toolbar, click “Lock view and show members in hierarchy” (should be the leftmost toolbar icon).
  • In the upper part of the view, you can browse through all implementations of the method.

The procedure isn’t very quick, but it gives you a good overview.

How do you build a .jar file in Eclipse


If you want to distribute your project as jar or as executable jar, you might need follow a very simple steps.

1. you can click on the project, go to File –> Export.

2. Select jar and a dialog will come up.

3. Then, just select your options and you should be set.

Eclipse–Decompiler to read the .class files while debugging

Installing this is very simple. Just drag and drop the icon in your running eclipse (Juno)


Hope this link still work works : –


JadClipse for Eclipse 4.x also support Eclipse 3.x, and provides several new features:

1. Integrate jad.exe into the plugin, don’t need to set jad path in the preference page again.
2. Add two options in the JadClipse main preference page:
(1) Use Eclipse member sorter
(2) Show decompiler report
3. Update the formatting preference default settings, the “Output fields before methods” setting’s default value changes to true.

IDE : Netbeans database explorer view


It is very handy to see the database changes then in there in the IDE specially when working on hibernate. Net beans has this beautiful service/plugin, where you can fire query, see result set, modify tables and can analyse the association like foreign key and relation ship between tables in the graphical form.

IDE : Eclipse Vs NetBeans


NetBeans is an open-source project dedicated to providing rock solid software development products.I love Net Beans and its free like eclipse (Idea Injelli J is cool but its a paid IDE). If you want to do a quick start, instead of wasting time in IDE setup especially for web application development my vote goes for Net Beans.

The other day I have to do some experiment in a struts web app, I started using eclipse, now it told me to download tomcat, struts libs, setup environment variables and so many things  before i can see my hello world app. Then I just downloaded Netbeans click on a sample project of struts, there it goes, with the eye blink, the entire project was ready, compiled with all dependencies and deployed on bundled tomcat Smile. I started playing with app and experimented what I had to learn without much hassels of project setup etc as i had to do with eclipse. The User interface is very intuitive.




Pros and cons

So, now that the two environments are on a fairly even footing in the features and functionality they provide, what’s the difference? A lot of it has to do with personal preference and what the IDE is being used for. In fact, many developers use both Eclipse and NetBeans — just for different projects or clients. Each solution still has its own drawbacks and frustrations. Here are two of the most common distinctions users make between the IDEs:

  • Ease of use
    According to quite a few developers, Netbeans is easier to navigate right out of the box as long as you don’t try to use all the bells and whistles at first. It’s potentially more difficult to grasp at an advanced level compared to Eclipse because you really have to know what you are doing in Java to complete more complex projects. It could be ideal for beginner Java developers who just need the basics to start with and who are willing to take a “learn as you go” attitude to the rest of the platform. At one time, NetBeans featured a more pleasing and intuitive interface than Eclipse; but Eclipse has improved in this department recently.
  • Plugins
    Eclipse has a huge array of plugins delivering capabilities that aren’t necessarily available with NetBeans. Sorting through the plugins and dealing with plugins that break because of updates to new versions can be a headache. Third-party plugins offer lots of variety but aren’t necessarily reliable because of a lack of quality control. This reliance on plugins has led to quite a few complaints about the stability of the Eclipse platform; there’s a lot that can go wrong as the number of plugins increases. That being said, if you get the right plugins, it can make life a lot easier.

NetBeans tools tend to be a little more standardized as part of the Sun/Oracle brand. For example, a GUI builder comes with the NetBeans platform while it’s only available as a plugin for Eclipse. At the same time, many Google development tools like those for Android are easily obtainable as plugins for Eclipse and are not part of the regular NetBeans package. Some plugins are available for NetBeans (including a few that can be ported from Eclipse), but these plugins introduce a whole different set of complexities and the plugin technology isn’t as mature for NetBeans when compared to Eclipse.

At this time, it appears that Eclipse will continue to dominate the field due to user familiarity and the availability of custom options. However, the fact that NetBeans is a viable option means Eclipse will need to keep their plugin issues under control to retain customer loyalty .
