Scala *only* as "Java without semicolons". Let's take a look. Equivalent Java-Scala pairs are presented below.

01-Point.java

// Let's say we want to create an immutable Point class

public class Point {

    public final double x;
    public final double y;

    public Point(final double x, final double y) {
        this.x = x;
        this.y = y;
    }

}

01-Point.scala

// Now, the same exact code in Scala:

class Point(x: Double, y: Double)

02-Point.java

// But what if we wanted to be able to to create (0,0) by default?

public class Point {

    public final double x;
    public final double y;

    public Point() {
        this(0, 0);
    }

    public Point(final double x, final double y) {
        this.x = x;
        this.y = y;
    }

}

02-Point.scala

// ;)

class Point(x: Double = 0, y: Double = 0)

03-Point.java

// Let's do something more serious: translation to polar coordinates!

public class Point {

    public final double x;
    public final double y;

    public Point(final double x, final double y) {
        this.x = x;
        this.y = y;
    }

    public double r() {
        return Math.sqrt(x * x + y * y);
    }

    public double phi() {
        return Math.atan2(y, x);
    }

}

03-Point.scala

// Equivalent code which you could even call from your Java code!

import scala.math

class Point(x: Double, y: Double) {

  // Everything is public by default
  def r = math.sqrt(x * x + y * y)

  // Notice how we don't need to specify return types because the
  // compiler is able to guess them (still it's static typing!)
  def phi = math.atan2(y, x)

}

04-Point.java

// And if we wanted a .toString() method?

public class Point {

    public final double x;
    public final double y;

    public Point(final double x, final double y) {
        this.x = x;
        this.y = y;
    }

    public String toString() {
        return "Point(" + x + "," + y + ")";
    }

}

04-Point.scala

// It's enough to add "case" before "class", to get a default
// .toString output of which looks like in above Java example:
// "CaseClassName(param1,param2,...)"

case class Point(x: Double, y: Double)

// (When using case classes we get some other advantages, as well.)
