Hi Sanjeev
Scala-labs is quite an old project (2009-2010) and it hasn’t been kept up to date very well. The labs themselves should be ok but Scala and the associated tools ecosystem have evolved quite a bit.
If you are looking for a full-blown IDE, you have two options:
- http://scala-ide.org/, which is based on Eclipse
- https://www.jetbrains.com/idea/features/scala.html using the free version of IDEA
I don’t use an IDE myself so I cannot offer you much help in choosing one over the other. I use Sublime Text 3 with the Scala syntax highlighter plugin and I run SBT from the command line.
Hope this helps
