I have a value like the below String original = "109,107,108";
now I have to remove 107 the comma in the front and the back and should get the output of the string like
String new="109,108"
value to be removed can be dynamic. if say I will get the value to be removed from the string from another method.
You can split the string at the comma, then remove the undesired values and join it again. Here's an example doing this using the Java 8 Streams API:
Arrays.stream("1,2,3".split(","))
.filter(part -> !part.equals("2"))
.collect(Collectors.joining(","))
Also I noticed you have the "CSV" tag in your question. If you plan to parse a CSV it would probably be better use a library like fast-csv or commons-csv instead. They will be more optimized and also support more complex cases like escapes.
