You can always play with regular expressions to achieve a desired result. Use the regex backreference and combine it with the greedy quantifier:

    void printRepeating(String arrayOfInt)
    {
        String regex = "(\\d+)\\1";
        Pattern patt = Pattern.compile(regex);
        Matcher matcher = patt.matcher(arrayOfInt);           
        while (matcher.find())                              
        {               
            System.out.println("Repeated substring: " + matcher.group(1));
        } 
    }
