一段使用Java生成随机数的代码

package testUtility;
import java.sql.Timestamp;
import java.util.Random;
public class RandomTest
{
  public static void main(String[] args) 
  {
    Timestamp d = new Timestamp(System.currentTimeMillis());
    int b = d.hashCode();
    System.out.println("timestamp: " + b);
    Random random1 = new Random(b);
    int a = random1.nextInt();
    if ( a < 0 )
      a = -a;
    System.out.println(a);
    System.out.println("Result: " + ( a + 825281 ) % 3);
  }
}
