You may need to extract or filter the date or time from a String or text. You can use the following program:
| The code is as follows: |
Copy code |
Public String run (String text ){
String dateStr = text. replaceAll ("r? N ","");
DateStr = dateStr. replaceAll ("\ s + ","");
Try {
List matches = null;
Pattern p = Pattern. compile ("(\ d {} [-| \/] \ d {} [-| \/] \ d }: \ d {1, 2 }:\ d {1, 2}) ", Pattern. CASE_INSENSITIVE | Pattern. MULTILINE );
Matcher = p. matcher (dateStr );
If (matcher. find () & matcher. groupCount ()> = 1 ){
Matches = new ArrayList ();
For (int I = 1; I <= matcher. groupCount (); I ++ ){
String temp = matcher. group (I );
Matches. add (temp );
}
} Else {
Matches = Collections. EMPTY_LIST;
}
If (matches. size ()> 0 ){
Return (String) matches. get (0). trim ();
} Else {
Return "";
}
} Catch (Exception e ){
Return "";
}
} |
The current function of this program is to extract from the string in the form of "yyyy-MM-dd HH: mm: ss" or "yyyy/MM/dd HH: mm: ss. If the time format is short, it cannot be processed, but it can be easily expanded.
