Kotlin online IDE & code editor for technical interviews

Guidelines to use Kotlin in this online IDE

Our Kotlin environment is built on top of our Java environment, giving you access to any libraries we have installed there, too.

For example, to run a JUnit test in Kotlin:

import org.junit.*;
import org.junit.runner.*;

fun main(args: Array<String>) {
  JUnitCore.main("Solution");
}

 class Solution {
  @Test
  fun testNoop() {
    Assert.assertTrue(true);
  }
