Random numbers in JavaME (and JavaSE)
In the absence of a Math.random() method in JavaME, you can use the java.util.Random class to do the job:
Random random = new Random(System.currentTimeMillis()); // JavaSE and CDLC 1.1 float f = random.nextFloat(); [0; 1[ // JavaSE and CDLC 1.0 int a = random.nextInt(); // [0; *[ int b = random.nextInt(20); // [0; 20[ int n = random.nextInt(max - min + 1) + min; // [min; max]
This tip can be used on JavaSE, if you want to generate a random number between "min" and "max". It is easier than multiplying and casting to integer.
