Quick Q: Are thread nested?

Question

consider this:
Thread thread1 = new Thread(new Runnable(){
    Thread2.start();
}).start();
thread1.sleep(100000);Will thread 2 continue unimpeded?
I would have assumed it would, as its kinda the point of threads as i understood them, but im having some unexpected behaviour, and clarification on this point will aid me with debugging.
Thank you

Ahh i see, that makes sense.
OK, with that in mind, i want a thread to perform a check every now and then (generally ~5minutes), would it be be bad practice to do the following?
new Thread(new Runnable(){
private void run(){
while(true){
if( timeElapsedSinceLastCheck > interval ){
perform check and respond
}).start();
If you don't put a sleep() inside that loop, then, yes, very bad idea.
