//        String mobile = "15688888888";
        String[] mobiles = new String[1];
        if (mobile.contains(",")) {
    
    
            mobiles = mobile.split(",");
        } else if (mobile.contains(" ")) {
    
    
            mobiles = mobile.split("  ");
        }else {
    
    
            mobiles[0] = mobile;
        }
        int i = 0;
        for (String telephone : mobiles) {
    
    
            i++;
            System.out.println(telephone);
