regarding objects and collections

[suresh sai]

hi,
the following code gives ClassCastException.

Object [] myObjects={new String("foo"),new Boolean(true),new Integer(5)};
Arrays.sort(myobjects);

Is it because of ,myObjects contain different type of objects or it is due to..Object is super class of Arrays.Please tellme ,How can I rectify the error?

Chinna,
First of all, you've got two same threads at https://coderanch.com/forums/f-33/java .
You can remove one of them by selecting it, clicking the edit icon of your post (here), checking the "Delete Post" checkbox and confirming.

Secondly, it's not cool to post the same question in different threads. Could you please continue in your original post ? Thank you.

That was obvious because all elements in the array were not mutually comparable.Read more at:

Please don't post the same question in multiple forums. It creates duplicate conversations and wastes the time of the people trying to help you.

Thanks,
