Easy question. Code won't compile missing semicolon System.exit(0) Throw an exception Kill JVM from task manager Naive solution: run through the list and put it in a hashmap and a count. Iterate over all the elements to see whose count is less than 2. That's yours answer Better solution: xor all the numbers in the list. The result is the one that didn't have a duplicate.
