Class used via an implicit conversion to enable a times method to be invoked
on Ints to repeat a given side-effecting operation multiple times.
Class used via an implicit conversion to enable a times method to be invoked
on Ints to repeat a given side-effecting operation multiple times.
When an instance of this class is constructed, 0 and any positive number may be passed as num,
but a negative number will result in an IllegalArgumentException. If constructed with 0, the times method
on the resulting instance will return without invoking the function passed to it. If constructed with 1, the times method
will invoke the function passed to it once then return.
IllegalArgumentException if num is less than zero.
Implicit conversion that adds a times method to Ints that
will repeat a given side-effecting operation multiple times.

the integer to which the times method will be added.
Trait providing an implicit conversion that adds a
timesmethod toInts 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:
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:
This trait enables
timesto be invoked on 0 and any positive integer, but attempting to invoketimeson a negative integer will result in anIllegalArgumentException.
