regex - Java, how to replace a sequence of numbers in a string

Question

I am trying to replace any sequence of numbers in a string with the number itself within brackets. So the input:

"i ee44 a1 1222"  

Should have as an output:

"i ee(44) a(1) (1222)"

I am trying to implement it using String.replace(a,b) but with no success.

Answer 1

"i ee44 a1 1222".replaceAll("\d+", "($0)");

Try this and see if it works.

Since you need to work with regular expressions, you may consider using replaceAll instead of replace.
