trait TimesOnInt extends AnyRef
Trait providing an implicit conversion that adds a times method to Ints that
will repeat a given side-effecting operation multiple times.
Here's an example in which a friendly greeting is printed three times:
3 times println("Hello again, world!")
Running the above code would yield this output:
Hello again, world! Hello again, world! Hello again, world!
If you need to repeat a block of statements multiple times, just enclose them in parentheses, like this:
2 times { print("Hello ") print("again, ") println("world!") }
Running the above code would yield:
Hello again, world! Hello again, world!
This trait enables times to be invoked on 0 and any positive integer,
but attempting to invoke times on a negative integer will result in an IllegalArgumentException.

num, but a negative number will result in anIllegalArgumentException. If constructed with 0, thetimesmethod on the resulting instance will return without invoking the function passed to it. If constructed with 1, thetimesmethod will invoke the function passed to it once then return.- Exceptions thrown
