Need help using split, how to get the number of inputs?

I am trying to write a program in which a user inputs several numbers, then the output is how many numbers were input. I am thinking that the best way to do this is to use split, however I am pretty new and can't get it quite down. Thanks

Sorry, I guess I didnt explain it correctly. The input would be something like this-
90 87 76 23 99
Here is what I have-
import java.util.*;
public class Scores {
  public static void main(String args[]) {
          int score;
          System.out.println("Input UNC Basketball scores, each separated by a space.");
          Scanner keyboard = new Scanner(System.in);
   int count = args[0].trim().split(?\\s?).length;
}The int count line was given to me by someone, however I dont know how to get there. Thanks

  • [Win VC++ 6.0 ]How to get the number of files count in a folder using VC++ 6.0?

    Hi all,

    I'm a little confused by the question, but it sounds like you're asking how to count the number of files with a particular extension in a given directory? That's not really an AI SDK question, but it's a fairly easy one to find if you google it. If you're trying to use Illustrator to do it, AI doesn't have a general purpose file API. It has a few functions to do some things that Illustrator needs, but I don't think enumerating directories is one of them.

  • How to get the number of decimal places configured for a site column

    Hi,
    I have a column 'SampleNumCol' of type Number, the number of decimal places to be displayed is configured as 2.
    The column conatins a value, but when retrieved programatically is displayed as 5.00000000  instead of 5.00.
    I am retrieving this column using listitem.Properties[field.InternalName].
    I need to trim the decimals based on  number of decimal places configured for the site column.
    How to get the number of decimal places configured for a site column?
    Thanks in advance,

    Get the field as SPFieldNumber and then check DisplayFormat which returns
    SPNumberFormatTypes
    SPFieldNumber numberField = list.Fields.GetFieldByInternalName("YourNumberFieldName") as SPFieldNumber;
    SPNumberFormatTypes numFormatType = numberField.DisplayFormat;

    When a file is uploaded, the file name is also submitted. The path of the file is available only to the machine within the Local Machine security zone. The value property returns only the file name to machines outside the Local Machine security zone. See About URL Security Zones for more information on security zones.
    i need to know on how to get the compelete path /directory of the filename
    using <input type="file"> tag You can't. Its a security thing.
    is there any other way to get an input file from a local host aside from <input type="file"> tag?No. Not using just html.
    You could always go into activex components, but thats different again.

  • How to get the number of columns in a result set???

    hi everyone..
    i am trying to establish a servlet applet communication....
    my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
    Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
    so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
    so is there a way to get the number of columns in a result set...???
    and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
    thanx in advance

    You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

  • How to get the number of elements in DB

    Could you tell me how to get the number of elements in DB??
    My code to get the number is below, but I think it is not efficient
    DB->cursor(DB, NULL, &cursorp, 0);
    while ((ret = cursorp->c_get(cursorp, &key, &data, DB_NEXT)) == 0)
    count++;
    --------------------------------------------------------------------------------------------------------------

    Hi,
    The most efficient way to get a count from the database is using the DB->stat API (http://docs.oracle.com/cd/E17076_02/html/api_reference/C/dbstat.html)
    The code will be something like:
            DB *dbp;
            DB_BTREE_STAT *statp;
            int ret;
            /* Print out the number of records in the database. */
            if ((ret = dbp->stat(dbp, NULL, &statp, 0)) != 0) {
                    dbp->err(dbp, ret, "DB->stat");
                    goto err1;
            printf("%s: database contains %lu records\n",
                progname, (u_long)statp->bt_ndata);
            free(statp);The code comes from the example included in the distribution at examples/c/ex_btrec.c
    If the database isn't a btree, you should update to the appropriate statistics structure and field.
    It's worth noting that retrieving the count is never a "cheap" operation. The count is not stored in the database - since doing so introduced a single point of contention that creates a bottle neck.

  • How to get the number of messages consumed by a MDB ??

    Hi all,
    How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
    DMS ??? what use DMS ???
    tanks

    ok.
    Well using DMS is one way to get at these sorts of stats in a programmatic manner.
    There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
    I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
    http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
    Which produces a table of the TEXT form:
    <DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>

    pooled.value:     0     count

    ready.value:     0     count
    session-type.value:     Stateless     
    transaction-type.value:     Bean     
    </statistics>
    </DMSDUMP>
    Or produces an XML document of the form:
    http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
    You can use the Spy console to find the table that contains the details for MDB and then take it from there.
    This is not what you specifically want to do, but it does provide a good overview of how DMS is used.

  • How to get the number of files currently open?

    hi,
    does any one know how to get the number of files currently open in windows OS?
    e.g. lets say .txt files...
    any comment will be really appreciated.
    thanks

    Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

  • How to get the number of bytes at TCP port

    Hi all,
    How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
    but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

    Hi
    In LabVIEW you don't have the same property as in serail port.
    You havn't "Byte at TCPIP port".
    if you developp a protocol, one soltion, is to send the size to read.

  • How to get the number of rows in a DB-Cursor

    When i open a database cursor i do not know how much rows are stored in the cursor. To solve this problem i have to send a 'select count(1) ...' to get the number of rows before i set up the cursor. I think that this is not very clever and could possibly cause performance problems. But i need the num of rows to show the percentage of processed rows. Is there any other way to get the num of rows? May be by checking the cursor directly?
    Please help!
    Thanx a lot

    In order to find out how may rows are going to be processed, oracle has to visit every row. So with a cursor, there is no property that will accurately reflect the number of rows until you get to the last one. That said, you could use
    select count(*) over() as row_count, <rest of your columns> FROM <your table>
    which will give you the total row count agaist each row in the result set. There are performance penalties involved but they will be less than issuing the query twice, once to get the count and once to get the rows.
    Have a look on asktom for some very usefull info about all this.
