Question

Android 2.3.3

I have an ArrayList which has both Numbers(in string format) and also words like (and, plus, by, …)

I wish to retrieve numbers only from this ArrayList.

I can get the value using get(index) and convert to number, if it a number that can be converted. If i use a loop to iterate, conversion of words will throw me an exception. So, how do i check, without getting an exception.

Will this work:::

I use a try catch block and when there is an exception, I just write “continue;” in the catch block.

Answer 1

You can try to convert in a try block, and ignore the exception in the catch block. (Just continue the loop, like you suggested). It will work.

Another method, without making use of exceptions handling;
