Java regex take numbers from String

Question

I want to take number's from string

example:

1223_:2 
234423_:5

I only want to take this number's to _:

any idea for

 Pattern p = Pattern.compile(??????????)

I'm not sure whether I got you right: do you want only the first part of the number (e.g. 1223) or the whole number without "_:" (e.g. 12232)? — s106mo

What’s with the regex requirement?

String number = someOtherString.substring(0, someOtherString.indexOf('_:'));

String str = "1223_:2 234423_:5";
String[] numbers = str.trim().split("_:\\d+\\s*");

For a better answer we are gonna need more details. What exactly do you want to do?
