Java: do something x percent of the time

Question

I need a few lines of Java code that run a command x percent of the time at random.

psuedocode:

boolean x = true 10% of cases.

if(x){
  System.out.p         


        

Answer 1

You have to define "time" first, since 10% is a relative measure...

E.g. x is true every 5 seconds.

Or you could use a random number generator that samples uniformly from 1 to 10 and always do something if he samples a "1".
