Regular expression to remove string with brackets

1. "10 10 [by]"
2. "1232 1232 [en]"

expected:

1. "10 10"
2. "1232 1232"

I want to get string without [] and value inside it.
I tried companyCodeValue1.replaceFirst("\s*([^[]]*)$", "") but I have issue with []…
Does anyone know how to implement regular expression for catching that case?

>Solution :

The regex you’re looking for it’s this one right here: \[.*\]

Pattern p = Pattern.compile("\\[.*\\]");
Matcher m = p.matcher("10 10 [by]");
String res = m.replaceAll("");
