Parse number with positive/negative prefix from string in java

Question

It\'s quite straight forward in java to parse number from String, i.e. with Integer.parseInt(s) if string in the format \'n\' or \'-n\', but unfortunately

Answer 1

Integer.parseInt(s.replace("+", ""));

In truth there are many gotchas using Integer to parse numbers like that, in that Integer has very specific bounds of size and format ("1,000,000.00") isn't parsing that way, but I'm taking your question as Integer.parseInt meets your needs just fine, you just have to deal with a + in your data.
