How the if-else statement is different for Scala and Java

Question

Can anyone explain the differences between the if-else statements for Scala and Java?

Answer 1

Hey,

There is one main difference. This statement is an expression in Scala, but not in Java. There, we cannot assign it to a variable because it doesn’t return a value.

Here is an example below:

scala> val x=3

x: Int = 3

scala> val kind= if(x%2==0) "even" else "odd"

kind: String = odd

Java:

int x=3;

String kind;

if(x%2==0)

kind=”even”;

else

kind=”odd”;

Hope this helps!
