scala - Is 'def eat():Unit = sleep(); def sleep(): Unit = eat()' a tail recursive function? -

-

two functions:

def eat(): unit = sleep() def sleep(): unit = eat()

both of them recursive functions, because called in body (indirectly), right?

but tail recursive functions?

both of them recursive functions, because called in body (indirectly), right?

yes, called mutual recursion.

but tail recursive functions?

yes, are, call return value of body. however, afaik scala compiler not optimise these while loops, self-recursive functions. see does scala support tail recursion optimization? details, , how use tailcalls? workaround.

this question understanding interfaces in java. here simple example of implementing interfaces in java. interface parenta { void display(); } interface parentb { int display(); } class child implements parenta, parentb { @override public void display() { system.err.println("child parenta"); } //error : return type incompatible parentb.display() //so added method int return type @override public int display() { system.err.println("child parentb"); } } this case can happen in large java application 2 interface can have method same name. thought since return type different jvm know interface's method overriding. what best explanation this? situation make sense? thanks in advance because method same signature not allowed, confuses compiler detect exact override-equivalent method declared once. jls (§8.4.2) 2 methods or constructors, m , n, have same signature if have, ...
