int atoi (const char * str); Convert string to integer. Parses the C-string str interpreting its content as an integral number, which is returned as a value of type int. The function first discards as many whitespace characters (as in isspace) as necessary until the first non-whitespace character is found.
The Math.* methods that handle the overflow conditions are good too. I am not sure if you intended it, but you also correctly handle an obscure edge-case in 32-bit signed integer systems (not just Java), where Integer.MIN_VALUE is not the same as - Integer.MAX_VALUE and your code actually gets it right for an exact input of the text
