Java replace string ignore spaces -

string msg = "123 test"; system.out.println(msg.replaceall("(?i)test", "****")); 

result: 123 ****

string msg = "123 te st"; system.out.println(msg.replaceall("(?i)test", "****")); 

result: "123 te st"

but want replace ignore spaces result: "123 ****"

what should change? "123 te st" "123 ****"

you should add blanks * wildcard regexp:

system.out.println(msg.replaceall("(?i)t *e *s *t", " ****"));
