You can check out this tutorial to find out more about String processing using Apache Commons Lang API. StringUtils.substringBefore(text, " was born")) The separator isn’t returned: assertEquals("Julia Evans", Equals/Compare - compares two strings in a null-safe manner. Trim/Strip - removes leading and trailing whitespace. Similarly, the substringBefore method gets the substring before the first occurrence of a separator. IsEmpty/IsBlank - checks if a String contains text. StringUtils.substringAfter(text, "living in ")) The separator isn’t returned: assertEquals("the USA (United States of America).", The substringAfter method from the same class gets the substring after the first occurrence of a separator. There is a simplified version of this method in case the substring is nested in between two instances of the same String: substringBetween(String str, String tag) StringUtils.substringBetween(text, "(", ")")) In this example, we’re going to see how to extract a substring nested between two Strings: assertEquals("United States of America", Use a better overload like String.split (String regex, int limit). String wantedPart lineOfText.substring (lineOfText.indexOf (',') + 1) Since indexOf returns the index of the, itself, you need to add one to get everything past it. Apache Commons Lang provides a host of helper utilities for the java.lang API, most notably String manipulation methods. Find the index (position) of the first, and substring using that index. The Apache Commons libraries add some useful methods for manipulating core Java types.
