java thread - how to have a thread that runs each second, and prefferably, in that thread have it do 1 action each 5 seconds?

I have a thread that runs each second with开发者_运维技巧 the sleep command. this works fine, but I'd like to have it do certain actions every 5 seconds too. Both things should run at the same time.. I've had problems starting a second thread in a first one...

any help please?

Thanks in advance!
