Features of Scala

1. Object Oriented
   1. Everything is an object.
   2. Unlike Java , where we have primitives/static fields and methods that are not members of any object.

Example: 1+2 is actually 1.+(2)

2. Functional
   1. Functions are first-class values or citizens.
   2. Encourages immutability where operations like map() , input values to output, rather than change data in place
3. Compatibility
   1. Compile to JVM bytecode
   2. Can call Java methods and fields
   3. Re-uses Java types
4. Concise

class Time(val hours: Int, val inutes: Int)


public class Time {

private final int hours;

private final int minutes;


public Time(int hours, int minutes) {
  this.hours = hours;
  this.minutes = minutes;
  }

public int getHours(){
  return hours; 
 }

public int getMinutes() {
   return minutes;
  }
}
