.collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append) .toString(); } As we can see, we used thelimit(text.length()-1)method to tell the stream to ignore and delete the last character. Apache Commons Lang3 Library The Apache Commons Lang libraryprovides theStringUt...

we need to keep another information: the last removal position. If we do not have this position, we will generate duplicate by removing two ‘)’ in two steps only with a different order.

3. Using Loop andStringBuilder Using aforloop with aStringBuilderprovides a straightforward approach to removing digits from aString. This method involves iterating over eachCharacterin theString, checking if it’s a digit, and then appending non-digitCharactersto aStringBuilder: ...
int last_tab_index = 0; int added_chars = 0; if (tabWidth == 0) { return StringUtil.remove(line, '\t'); } StringBuilder result = new StringBuilder(); while ((tab_index = line.indexOf('\t', last_tab_index)) != -1) { tab_size = tabWidth - ((tab_index + added_chars)...
