Searching for a substring within a string

can someone reccomend a simple way to search for a substring within a string and count the number occurences of that substring.
The substring and the string will be provided as command line parameters.
Thanks

A simple way would be to use the indexOf methods in String:
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
Not sure what this has to do with event handling though :-P

Help me about Searching for a Substring within a String

Hello everybody,
I have a problem like this:
Assume i type a sentence from keyboard: "I want to play football"
And computer will look for the word "football" to see if this word is in that sentence.
In this case, computer found it.
That is it ! Could anybody help me about this ?
Thank you very much in advance.

Use the String.indexOf() method:
String original = "I want to play football";
int result = original.indexOf("football");
if (result != -1)
System.out.println("computer found it");
If the word "football" is in the original String, the indexOf() method will return the index of the word. If it does not find the word "football", it will return a value of -1. The String API is full of useful methods.

I'm looking for the substring:
YWY,1,YWYWhy do you want that substring. Do you always want the last 9 characters of the string?
If you're looking for a substring that starts with 'YWY', and then has any number (including 0) of commas, digits, and additional 'YWY' strings after it, then:
REGEXP_SUBSTR ( str
, 'YWY[,[:digit:]]*)
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, maybe 5 or 10 rows), and also post the results you want from that data. Include examples of any special cases you need to handle (e.g., the target pattern is not found at all, or it is found at 2 different places in the string).
Explain, using specific examples, how you get those results from that data. Say what your business rules are.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

How to search for upper/lower case using string using JAVA!!!?

-I am trying to write a program that will examine each letter in the string and count how many time the upper-case letter 'E' appears, and how many times the lower-case letter 'e' appears.
-I also have to use a JOptionPane.showMessageDialog() to tell the user how many upper and lower case e's were in the string.
-This will be repeated until the user types the word "Stop".
please help if you can
what i have so far:
[code]
public class Project0 {
public static void main(String[] args) {
String[] uppercase = {'E'};
String[] lowercase = {'e'};
String isOrIsNot, inputWord;
while (true) {
   // This line asks the user for input by popping out a single window
   // with text input
   inputWord = JOptionPane.showInputDialog(null, "Please enter a sentence");
   if ( inputWord.equals("stop") )
    System.exit(0);
   // if the inputWord is contained within uppercase or
   // lowercase return true
   if (wordIsThere(inputWord, lowercase))
    isOrIsNot = "Number of lower case e's: ";
   if (wordIsThere(inputword, uppercase))
     isOrIsNot = "number of upper case e's: ";
   // Output to a JOptionPane window whether the word is on the list or not
   JOptionPane.showMessageDialog(null, "The word " + inputWord + " " + isOrIsNot + " on the list.");
} //main
public static boolean wordIsThere(String findMe, String[] theList) {
for (int i=0; i<theList.length; ++i) {
   if (findMe.equals(theList[i])) return true;
return false;
} // wordIsThere
} // class Lab4Program1
[/code]

So what is your question? Do you get any errors? If so, post them. What doesn't work?

Searching for a substring

after running through the forums i couldn't find anything that related to my question. so here it is.
to search for a substring, do i have to search for each individual character or is there an easier method...
for example:
String john,paul,mark,fabio,greg,park,rego
if i wanted to find all the strings with "ar" in them, would i have to search for a, and then r and check if the position of r is +1 a??
or is there an easier way??
thanks for your help!

The documentation is your friend.

Look up what the method indexOf(String) of the class java.lang.String does.

How do I search for a word within a web page

Search for White space within strings

create table emp_dtl
(empname varchar2(23));
Insert into emp_dtl values ('WAYNE');
Insert into emp_dtl values ('JOSEPH KRUPP');     --------- has white space
Insert into emp_dtl values ('YING ZONG LEE');    --------- has white space
Insert into emp_dtl values ('COHEN');
Insert into emp_dtl values ('MARIE');How can i search for empnames which has White space in it? From other OTN threads, I gathered that this has something to do with
chr(32)But i don't know how to put this in LIKE operator.

Hi,
SELECT *
FROM    emp_dtl
WHERE   REGEXP_LIKE (empname, '\s')
;will look for any kind of whitespace (including spaces, which are CHR (32)).
It may be more efficient to specifically list all the different whitespace characters, and see if the string changes when you remove all of them:
SELECT     *
FROM     emp_dtl
WHERE     empname != TRANSLATE ( empname
                       , 'x ' || CHR (9)     -- CHR (9) = <tab>
                                      || CHR (10)     -- CHR (10) = <newline>
                             || CHR (13)     -- CHR (13) = <return>
                       , 'x'

How can I use SQL to search for a pattern within a field?

Hello, Frank, Solomon, ect
I am now faced with this particular scenario, I've got the SQL to search through a field to find text within the field, but I have to know what it is before it can look for it.
What I have to do is this:
Search through a field, for a pattern, and I won't know what the data is I am looking for. Can this be done in SQL?
For instance, Here is my SQL this far, I was helped allot in order to get to this point.
select table_name,
       column_name,
       :search_string search_string,
       result
from (select column_name,
               table_name,
               'ora:view("' || table_name || '")/ROW/' || column_name || '[ora:contains(text(),"%' || :search_string || '%") > 0]' str
          from cols
         where table_name in ('TABLE1', 'TABLE2')),
       xmltable (str columns result varchar2(10) path '.')
When you execute the above SQL, you have to pass in a value. What I really need is to alter the above SQL, to make it search for a pattern that exist's within the text of the field itself.
Like for instance, lets say the pattern I am looking for is this" xx-xxxxx-xxxx" and it's somewhere in a field.
I need to alter this SQL to take this pattern and search through all the schemas and tables to look for this pattern match.
Can be done?

When you use something dynamically within a function or procedure, roles do not apply and privileges must be granted directly. So, you need to grant select on dba_tab_cols directly. If you want to do pattern matching then you should use regular expressions. The following example grants the proper privileges and uses regexp_instr to find all values containing the pattern xxx-xxxx-xxxx, where /S is used for any non-space character. I limited the tables in order to save time and output for the test, but you can eliminate that where clause.
SYS@orcl> CREATE USER test IDENTIFIED BY test

SYS@orcl> ALTER USER test QUOTA UNLIMITED ON USERS

Search for certain Characters within set of Characters - in a field

Hello -
I know a search can be made within a field for a word, but I am not to sure, or I don't know how to accomplish this...To do a search in a field for certain characters within a larger set of charcters.
For example: I would search, in the Call Description field, for DXXXX within CA0001DXXXXYYY or search for LXXXX within CA0001LXXXXYYY, the X is numeric characters and the Y's are Alpha characters. Can crystal accomplish this....
Thanks for your gracious help....
G.

Like I said earlier, this code:
If instr({database_field}, 'DXXXX') > 0 then "String Found" else "Not Found"
cannot be used in a Record Selection formula.
The following code can be used in the Record Selection formula:
Instr({database field}, "string") > 0
If you wish to search for 'D4444' in the field and return records where a match is found, you would use:
Instr({database field}, "D4444") > 0

Searching for percent character (%) in a string

Hi All,
A strange request from one of our developers that I have not come across before.
Is there a way to search for a percent character (%) in a string and also use the wildcard special character (%)?
i.e. to return all values with a percent character (%)
e.g. select column1 from table1 where column1 like '%%';
When I do this all records are returned.
Regards!!
