Get random numbers in a specific range in java










I want to generate random numbers using




java.util.Random(arg);


The only problem is, the method can only take one argument, so the number is always between 0 and my argument. Is there a way to generate random numbers between (say) 200 and 500?


Answer



Random rand = new Random(seed);
int random_integer = rand.nextInt(upperbound-lowerbound) + lowerbound;
