What is Scala?● Scala is a blend of object oriented programming and a
functional one. This mixture is the source of its strength.
● Scala is compatible with Java. The two languages are
interoperable with each other. We can integrate the code
we write in Scala with our code in Java and vice verso.
● Scala is kind of an improvement to Java. Not only that
Scala re-uses Java's types it also “dresses them up”.

Shorter CodeLi fe M
ic hae l .c o
m● Comparing with Java, when using Scala our code becomes
significantly shorter.
class Rectangle {
private double width;
private double height;
public Rectangle (double width, double height) {
this.width = width;
this.height = height;
}
}

The Scala Story● The design of Scala started in 2001 at EPFL by Martin
Odersky, who had previously worked on developing the
first Java compilers.
● Typesafe was founded in 2011 in order to assist
companies with the development of software
applications using the Scala programming language and
its frameworks.

Scala in The Industry● Scala is highly popular on the server side. Many of the
companies that use Scala are either startup based with
highly talented people or very big companies with the
required budget.

IDEs for Scala Development● You can develop in Scala using the command line. You
can alternatively use one of the available Java IDEs. You
will need to install a plugin that allows coding in Scala.
