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", contains(), indexOf(), or matches() method of class. Similarly, the substringBefore method gets the substring before the first occurrence of a separator. There are many ways to check SubString in String in Java e.g. String substring () The substring () method has two variants and returns a new string that is a substring of this string. StringUtils.substringAfter(text, "living in ")) ![]() The separator isn't returned: assertEquals("the USA (United States of America).", str1.toUpperCase ().contains (str2.toUpperCase ()) UPD: Original answer was using toLowerCase () method. 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) Getting a Substring Starting at a Specific Character. It's provided by the String class itself and is very efficient. StringUtils.substringBetween(text, "(", ")")) The first and foremost way to check for the presence of a substring is the. In this example, we're going to see how to extract a substring nested between two Strings: assertEquals("United States of America", ![]() Apache Commons Lang provides a host of helper utilities for the java.lang API, most notably String manipulation methods. The Apache Commons libraries add some useful methods for manipulating core Java types.
