Does googles guava have a java tryparse integer method or something similar?

Question

I have the java guava library, and was wondering if they have a tryparse type helper method that will attempt to parse a string to a integer, and return a boolean if it failed.

In c#, I can do:

if(int.tryparse("somestring", out myInt)) {

}

Was hoping java has something similiar (don't want to re-invent the wheel if it exists).

Answer 1

Guava has Ints.tryParse(String) as of 11.0. It doesn't work quite like the C# method (no out parameters) though. It returns an Integer that's null if the string couldn't be parsed, so for your example you'd use it like this:

Integer myInt = Ints.tryParse(someString);
if (myInt != null) {
  ...
}

Answer 2

It looks like this was set to be added to release 11. The status is set to fixed, which I would think means it's either in the current release or will be in the next.

EDIT: It is in the API for 11: tryParse
