How to add multiple statements inside a when statement in kotlin

Question

I am trying to have multiple statements for one condition. For example: this is a sample code for when statement.

when (x) {     1 -> print("x == 1")     2 -> print("x == 2")      else -> { // Note the block         print("x is neither 1 nor 2")    } } 

When x is 1, I also want to have an extra statement like x += 10, how can I do it?

You have the solution in your question with the "Note the block" comment. Branches of when can be blocks that can contain any number of statements:

when(x) {     1 -> {         println("x == 1")         x += 10         println("x == 11")     }     2 -> { ... }     else -> { ... } } 

Writing a single statement branch just has a simplified syntax so that you don't need to surround it with {}.
