我在试着编程，很简单的取随机数，可就这样也不对，我不知道哪里错了，编译时没问题，而且在Eclipse环境下运行JSimpleBug的例程也没出错，可为什么我这个简单的试验程序却出错了呢？帮帮忙吧。在Eclipse环境下。
import swarm.Globals;

public class test {
/**
  * @param args
  */
public static void main(String[] args) {
   
     int y=(int)(10*Math.random());
     System.out.println("result is "+y);

     double z=Globals.env.uniformDblRand.getDoubleWithMin$withMax(0.0, 1.0);
  System.out.print(z+" re");
  }
}

结果是：
result is 2
