Use of Boolean? in if expression

Question

If I have a nullable Boolean b, I can do the following comparison in Java:

Boolean b = ...;
if (b != null && b) {
   /* Do something */
         


        

Answer 1

You can do with safe Operator "let"

val b: Boolean? = null
b?.let { flag ->
    if(flag){
        // true Block
    } else {
        // false Block
    }
}
