Answer 1

You may juse use String.replaceAll and use 2 regexes

• (0+)+ to remove zeros followed by a +
• +(0+), specific case when zeros are the last one, the + is before it

List<String> values = Arrays.asList(
    "12+00+9+88",
    "12+0+9+88",
    "00+9+88",
    "0+9+88",
    "12+00",
    "12+0"
);

for (String s : values) {
    String r = s.replaceAll("(0+)\+", "").replaceAll("\+(0+)", "");
    System.out.println(r);
}

12+9+88
12+9+88
9+88
9+88
12
12
