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 can use Random. You may want to seed it, but the default is often sufficient.

Random random = new Random();
int nextInt = random.nextInt(10);
if (nextInt == 0) {
    // happens 10% of the time...
}
