Java String.replaceFirst() replaces the first occurrence of a substring found that matches the given argument substring (or regex).
Find the first occurrence of the letter "e" in a string, starting the search at position 5: publicclassMain{publicstaticvoidmain(String[]args){StringmyStr="Hello planet earth, you are a great planet.";System.out.println(myStr.indexOf("e",5));}} ...
This “going further” makes it possible to have an exception at the end that collects the information about all discovered exceptional cases and not only the first occurrence. If you look at the code, you will also find there the original text of this article, and the setup that helps to...
