How to check Serial.list[] for an empty String[] array return value?

realogics

The following line of code produces an "ArrayIndexOutOfBoundsException" when no COM port exist.

myPort = new Serial(this, Serial.list()[0], 57600);

How do I check Serail.list() return value for an empty string array to avoid an exception?

Obviously the following will not work cause index 0 does not exist:

if (Serial.list()[0].length() != 0)
{
  myPort = new Serial(this, Serial.list()[0], 57600);
}

GoToLoop

import processing.serial.Serial;

final String[] ports = Serial.list();
printArray(ports);
println();

if (ports.length == 0) {
  println("No ports found!");
  exit();
}
