Groovy

def pattern = /1010/def input = "1010"def matcher = input =~ patternif (input ==~ pattern) {  input = matcher.replaceFirst("0101")  println(input)                            //0101}

Java

Pattern pattern = Pattern.compile("1010");String input = "1010";Matcher matcher = pattern.matcher(input);if (matcher.matches()) {  input = matcher.replaceFirst("0101");  System.out.println(input);              //0101}
