为什么我的Class.forName()抛出的异常不是ClassNotFoundException，而是RuntimeException?
try   {
    Class   c   =   Class.forName( "aaaaa ");
    c.newInstance();
}   catch   (Exception   e)   {
    if   (e   instanceof   ClassNotFoundException)
        System.out.println( "ClassNotFoundException ");
    else   if   (e   instanceof   RuntimeException)  
        System.out.println( "RuntimeException ");
}

------解决方案--------------------
绝对是ClassNotFoundException

你真的执行过吗


------解决方案--------------------
度过ClassNotFoundException
