I'm Currently learning Java Swing and I'm trying to generate a random number except when the number is generated it needs to figure out how many figures it is(1-10) and then pause for half a sec display the 1st number pause for half a sec display the 2nd number etc.
pretty much like this:
number generated 1256
1(1/2 sec)2(1/2 sec)5(1/2 sec)6
here is my code so far:
