Valid Number ( Java )

LeetCode

Validate if a given string is numeric.
Some examples:
"0" => true
" 0.1 " => true
"abc" => false
"1 a" => false
"2e10" => true
Note: It is intended for the problem statement to be ambiguous. You should gather all requirements up front before implementing one.

This is really a trivial question, a lot of corner cases need to be found, just like the Stirng to Integer question.
