Implement nested loop with condition in Scala

java, scala

Solution

You can use `Range` and friends:

if (((1 until 10 by 2) intersect (1 until 10 by 3)).isEmpty)
  System.out.println("no intercept")

This doesn't involve a nested loop (which you refer to in the title), but it is a much more idiomatic way to get the same result in Scala.

Edit: As Rex Kerr points out, the version above doesn't print the message each time, but the following does:

(1 until 10 by 2) filterNot (1 until 10 by 3 contains _) foreach (
   _ => println("no intercept")
)

Problem

What is an idiomatic way to implement the following code in Scala? ``` for (int i = 1; i < 10; i+=2) { // i = 1, 3, 5, 7, 9 bool intercept = false; for (int j = 1; j < 10; j+=3) { // j = 1, 4, 7 if (i==j) intercept = true } if (!intercept) { System.out.println("no intercept") } } ```
