There is no difference in any programming language If-Else.

Syntax:

if(Boolean_expression){
   //Executes when the Boolean expression is true
} else{
   //Executes when the Boolean expression is false
}

Hey,

Java’s “If. Else”:
In Java, “If. Else” is a statement, not an expression. It does not return a value and cannot assign it to a variable.

Here is an example you can follow to get the difference:

int year;

if(count == 00

year = 2014;

else

year = 2015;

Scala’s “If. Else”:
In Scala, “If. Else” is an expression. It evaluates a value i.e. returns a value. You can assign it to a variable.

val year = if (count == 0) 2014 else 2015

Scala’s “If. Else” works like Java’s Ternary Operator. You can use Scala’s “If. Else” like Java’s “If. Else” statement as shown below:

val year = 0 

if( count == 0) 

year = 2014 

else

year = 2015

if you intend to reassign you cannot declare year as val
