“One of the best programming skills you can have is knowing when to walk away for awhile.” — Oscar Godson
Scala
- Incorporates functional and object-oriented programming.
- Not compatible with its previous versions.
- The code written in Scala is generally more compact than the same code written in Java.
- Supports delaying the evaluation of an expression until its value is needed, i.e., lazy evaluation.
- Supports operator overloading.
- It takes more time to compile code than Java.
- Treats a function as a variable.
Java
- Incorporates object-oriented programming, and has started to support very limited functional programming in recent versions.
- Compatible with its previous versions.
- The code written in Java is generally less compact.
- It does not support lazy evaluation.
- It does not support operator overloading.
- Code compilation takes less time than it does in Scala.
- Treats a function as an object.
