10. contains

Fn: The contains function is used to determine whether the source string contains a substring. It includes two parameters: string and substring. They are both String types. distribution indicates the source string and sub-String. The returned result is a boolean value. The following is an example.

$ {Fn: contains ("ABC", "")}

$ {Fn: contains ("ABC", "")}

The former returns "false", and the latter returns "true ".

11. containsIgnoreCase

The fn: containsIgnoreCase function is similar to the fn: contains function. The only difference is that the fn: containsIgnoreCase function is case-insensitive for the inclusion of sub-strings.
DEMO code:
$ {Fn: containsIgnoreCase ("ABC", "")}

$ {Fn: containsIgnoreCase ("ABC", "")}

Both the former and the latter return "true ".

12. indexOf

The fn: indexOf function is used to obtain the starting position where the substring matches the source string. If the substring does not match the content of the source string, "-1" is returned ".

DEMO code:

$ {Fn: indexOf ("ABCD", "aBC ")}

-1 is returned because no matching is successful.

13. length

Obtain the length of the result set, similar to the size method defined by java. util. Collection interface.

DEMO code:

$ {Fn: length (sessionScope. arrayList1 )}

14. replace

Fn: The replace function allows replacement of source strings.

DEMO code:

$ {Fn: replace ("ABC", "A", "B ")}

Replace the "ABC" string with "BBC" and "A" with "B" in the "ABC" string ".

15. split

Fn: The split function is used to convert a group of strings separated by delimiters into string arrays.

DEMO code:

$ {Fn: split ("A, B, C ",",")}

Convert the string "A, B, C" to an array {A, B, C }.

16. startsWith

Fn: The startsWith function is used to determine whether the source string conforms to a series of specific word headers.

DEMO code:

$ {Fn: startsWith ("ABC", "AB ")}

Returns false.

17. substring

Fn: The substring function is used to intercept a string. Its parameters, returned results, and descriptions.

DEMO code:

$ {Fn: substring ("ABC", "1", "2 ")}

The Truncation result is "B ".

18. toLowerCase

Fn: The toLowerCase function allows you to convert all characters in the source string to lowercase characters.

DEMO code:

$ {Fn: toLowerCase ("ABCD ")}

The conversion result is "abcd ".

19. toUpperCase

Fn: The toUpperCase function allows you to convert all the characters in the source string to uppercase or lowercase characters.

DEMO code:

$ {Fn: toUpperCase ("abcd ")}

The conversion result is "ABCD ".

20. trim

Fn: the trim function deletes the "space" at the end of the source string to generate a new string.

DEMO code:

$ {Fn: trim ("AB C")} D

The conversion result is "AB cd". Note that it will only delete spaces at the end of the word rather than all. Therefore, there is still a space between "B" and "C.
