Java timer

[RobMunfy]

Hey,

I'm trying to pass a variable to the Timer() constructor. I am receiving the following error message:

cannot resolve symbol - constructor Timer(double, Spawn.Ticker)

I have a function in my code that returns a random double, which is the number that I want to pass to the first bit of Timer().

The code looks like this:

double a = getRandomDouble(0.3,0.9);
Timer t = new Timer(a, new Ticker());
t.start();

and the getRandomDouble is:

private double getRandomDouble(double lower, double higher)

Anyone know how I can pass a variable to the Timer constructor?

Cheers, Rob

Where is the Timer class coming from? Do you have the class definition for it?

Hi, it's part of the swing package, i used it from here:

Well javax.swing.Timer is expecting an integer and an ActionListener as a parameter to the constructor and your giving it a double and Spawn.Ticker(I don't know the type) so you need to be giving it the correct types.

Timer(int delay, ActionListener listener)

ahhh, yeah i'm being silly, just need to change my double to an int!

thanks for your help.
