form practicing java point of view , here is in brief what is the difference

you have function that do a mathematical division and may be a a division by zero exception raises up, so you need to tell anybody uses this function to handle this exception so you throws this exception from your function

public float yourFunction() throws ArithemeticException{

//function body

}

and if you want to rethrow or throw and exception to be propagated to the next handler, or throw your own Exception

try{

}Catch(Exception e){

throw e;

throw YourException();

}
