Signature: StringUtils.substringsBetween(inputString, open, close)

Returns: String[] result - the substrings, or null if no match

Example¶

// Typical usage: returns ALL substrings found between open and close
StringUtils.substringsBetween(
    "lion, and tiger, and bears, oh my!",
    "lion",
    "bear"
); // [", and tiger, and "]

// If open or close is not found, returns null
StringUtils.substringsBetween(
    "lion, and tiger, and bears, oh my!",
    "not found",
    "zz"
); // null

// Multiple matches are returned in order
StringUtils.substringsBetween(
    "one and two and three and four and five",
    "and",
    "and"
 ); // [" two ", " four "]

// If inputString is null, returns null
StringUtils.substringsBetween(null, "[", "]"); // null

// If open or close is empty or null, returns null
StringUtils.substringsBetween("abc", "", "]");   // null
StringUtils.substringsBetween("abc", "[", null); // null
