Integer.parse(String str) java.lang.NumberFormatException: Errors

Question

I keep getting number format expectations, even though I\'m trimming the strings and they don\'t contain non numerical characters bizarrely it works for some numbers and not

Answer 1

The largest number parseable as an int is 2147483647 (2³¹-1), and the largest long is 9223372036854775807 (2⁶³-1), only about twice as long.

To parse arbitrarily long numbers, use:

import java.math.BigInteger;

BigInteger number = new BigInteger(str);
