以下代码正常运行！

 ScriptEngineManager mgr = new ScriptEngineManager();
 ScriptEngine engine = mgr.getEngineByName("JavaScript");
 try {
      System.out.println(engine.eval("1/5"));
    } catch (ScriptException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

您不能在Javascript中按整数划分对象，说明问题发生的原因
