String str = "The quick brown fox jumps over the lazy dog."; String startDelimiter = "quick"; String endDelimiter = "jumps"; String result = StringUtils.substringBetween(str, startDelimiter, endDelimiter); System.out.println(result); // Output: " brown fox "
String str = "The quick brown fox jumps over the lazy dog."; String startDelimiter = "o"; String endDelimiter = " "; String[] results = StringUtils.substringsBetween(str, startDelimiter, endDelimiter); Arrays.asList(results).forEach(System.out::println); // Output: ["qu", "br", "fo", "j", "ov", "the", "lzy", "dog."]This example finds all the substrings between "o" and " " (space) in the given string and returns an array of strings. StringUtils class is part of the Apache Commons Lang library, which provides a set of utility classes for Java.
