perl - How can I check if an object has a specific method?

Question

I want to use a method of an object. Like $myObject->helloWorld().

However there are a couple of methods so I loop through an array of method names and call the method like this:

my $methodName ="helloWorld";
$myObject->$methodNames;

This works quite nice but some objects don't have all methods.

How can I tell whether $myObject has a method called helloWorld or not?

You can use the UNIVERSAL::can method of all objects to determine what methods it supports:

if ($myObject->can($methodName)) {
    $myObject->$methodName;
}
