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

To take your code as a base, you could simply do it like that:

if(Math.random() < 0.1){
  System.out.println("you got lucky");
}

FYI Math.random() uses a static instance of Random
