Converting String type to inte type

Can any one tell me how I can convert an array of Strings into an array of integers??

it's simple ..... it's like this...
   // some code goes here....
   String num[]={"23", "342", "21", "1"};
    int n[]= new int[num.length];
    for(int i=0; i<num.length; i++)
         n=Integer.parseInt(num[i]); // << -- convert string to int then copied it to int[]
// rest of your code....

How to convert String array into int.

void getSoldSms(Vector vecSoldSms)
     String str[]=new String[vecSoldSms.size()];
     String words[]=new String[str.length]; // String array
          for(int i=0;i< vecSoldSms.size();i++)
               str=(String)vecSoldSms.get(i);
          }               //End for
          for(int i=0;i<str.length;i++)

          } // end inner for loop
          }          //End for
     }          //End function getSoldSms
how do i convert words which is a string array into int type. i kno string can be converted into int using interger.parseint. but wat abt string arrays??? plz help me out with the above code.

i did tht its still giving the same errorFor Heaven's sake, what about taking a second to try to understand the code you're copying first? If you really can't fix the error yourself, you have a more serious problem than just convertingStrings to ints.
And if you want { "1", "2", "3" } to be 123:
StringBuffer b = new StringBuffer();
for (int i = 0; i < array.length; i++) {
b.append(array);
int result = Integer.parseIn(b.toString());

Converting string to an int

hi,
is there anyway i can easily convert a string into a long int.
I have an id string which consists of 11 characters, the first 3 are used to identify the type. the last 8 are numbers that need to go in a sequence.
Eg, 44400000001, next would be 44400000002 and so on.
i can break the string into two, but when i convert the last part into an int it does not keep the 0s. i need the length of this int to remain 8.
thanks

How do you mean, keep the zeros?
int is short for integer, it doesn't have length as in number of characters...
What about keeping the last part as String as well and converting it inside the calculations (or whatever you're doing)... or maybe convert it and do what you're doing and then convert it back to String with padded zeros?

How can I convert a String into an int?

I need to use command-line args. So I enter "java Main 123" and I want to use 123 not as a String but as an int.
How can I convert it into an int?
Thank You!!
Sprocket

Example method (you don't need to use a method unless you do this a lot)
private int stringTOInt (String aString)
int result = 0;
try
result = Integer.parseString(aString);
catch (Exception ex)
System.out.println ("Failed to convert string " + aString + " to int.");
return result;
}

Incompatible types - found java.lang.String but expected int

This is an extremely small simple program but i keep getting an "incompatible types - found java.lang.String but expected int" error and dont understand why. Im still pretty new to Java so it might just be something stupid im over looking...
import java.io.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
public class Lab
public static void main(String []args)
int input = JOptionPane.showInputDialog("Input Decimal ");
String bin = Integer.toBinaryString(input);
String hex = Integer.toHexString(input);
System.out.println("Decimal= " + input + '\n' + "Binary= " + bin + '\n' + "Hexadecimal " + hex);
}

You should always post the full, exact error message.
Your error message probably says that the error occurred on something like line #10, the JOptionPane line. The error is telling you that the compiler found a String value, but an int value was expected.
If you go to the API docs for JOptionPane, it will tell you what value type is returned for showInputDialog(). The value type is String. But you are trying to assign that value to an int. You can't do that.
You will need to assign the showInputDialog() value to a String variable. Then use Integer.parseInt(the_string) to convert to an int value.

How to insert int type array value to String type value?

public class wood
     public static void main (String args[])
          int a[]={1};
          String b[]={" "};
          b=a[0];
}how can I do it??I know it is int type, but how to insert a[0] to b[0]?

I don't understand this statement.
What I want to know is
1) why are you trying to convert an int[] to a String[]
2) are you trying to convert from a int[] to String[] or from an int[] to a String (i.e. treating the ints as chars or even simply concatenating there String values to a single String) and , once again why
There is probably a better way to accomplish your goals, but without cleary stating your goals we cannot help you. And as far as there being multiple int values, so what, the code snippet I posted would work for a hundred int values, you would just need to make the String[] long enough and loop through the values, you can't just simply do it all at once (unless of course, they are to be treated as char values, in which case you can probably cast your int[] to a char[] and use new String).

Convert String variable value to an Object referece type

Hi all,
I want to know that if there any possible way to convert String variable value to a Object reference type in java. I'll explain by example if this is not clear.
Let's think that there is a string variable name like,
String name="HelloWorld";
and there is a class name same to the variable value.
class HelloWorld
I am passing this string variable value to a method which is going to make a object of helloworld;
new convertobj().convert("HelloWorld");
class convertobj{
public void convert(String name){
// in hert it is going to create the object of HelloWorld;
// HelloWorld hello=new HelloWorld(); just like this.
now i want to do this from the name variable value.( name na=new name()) like wise.
please let me know if there any possible way to do that.
I am just passing the name of class by string variable then i wanted to make a instance of the class which come through the variable value.
thanx.

Either cast the object to a HelloWorld or use the reflection API (Google it) - with the reflection API you can discover what methods are available.
Note: if you are planning to pass in various string arguments and instantiate a class which you expect to have a certain method... you should define an interface and have all of your classes that you will call in this way implement the interface (that way you're sure the class has a method of that name). You can then just cast the object to the interface type and call the method.

Error in converting character string to smalldatetime data type

I've installed SQL Server 2000 on my new laptop and Crystal Report XI, out of sudden, the Crystal Report to certain view can't run and I got the following error:

Question about java reflection and "int" type

hi, using reflections I should invoke a Method (meth3) that have as parameter an INT type (not integer). I've tryed with this code:
                    int num = 3;
                    Class[] vettClax = {int.class};
                    Object[] vettParam = {num};
                    Method meth3 = temp.getMethod("meth3", vettClax);
                    meth.invoke(o, vettParam);My problem is that the int value is catched as an Integer value and reflection doesn't found a method that accept an INTEGER as parameter, who can help me?

Works fine when I try it.
public class t
    public static void main(String args[])
     throws Exception
     Class temp = t.class;
     t o = new t();
     int num = 3;
     Class[] vettClax = {int.class};
     Object[] vettParam = {num};
     Method meth = temp.getMethod("meth3", vettClax);
     meth.invoke(o, vettParam);
    public void meth3(int n)
     System.out.println("hello " + n);
}Is your meth3() public?

Data is not updating in calss & Convert vi reference to strictly type reference vi

Hi,
In the attached project file there is a Class called 'ClassSample.lvclass' having 3 different data types Boolean, Numeric and Variant(not really sure, Variant can be use for strict data type reference). From this three we careated the 'VIs for data member access' you can see them in project file
My questions are,(Please refer attached screenshot)
1. Though member of same class, why value is not updating at probe 16 ?
2. How to convert vi reference to strictly type reference vi ?
Thank you.

It depends a bit on your final intention. Bascially you have a shared state that you want to access asynchronously from different places. If you know that the actual object is only created once (terminilogie here is a bit shaky as every wire split would create a copy of the LVOOP object but I hope you know what I mean), you could use a global or Action Engine to store the state. Using a DVR for this state and adding the DVR to your object class data is however a more scalable approach as it will allow you to instantiate more than one object of that class and each one will contain its own DVR that will reference the same value for the specific object instance even if you split the object wire, creating actually two copies of that object (but for the purpose of this discussion they would be still the same object instance).
Queues could work if you create a single element queue but you would always need to use Preview Queue rather than Dequeue in order to maintain the value in there.

Converting OBJECT Type into RECORD Type

folks,
Is there a way to Convert a OBJECT Type into a RECORD Type in Oracle PL/SQL, Because i have a stored procedure with RECORD Type as a IN parameter and as we know that we JDBC doesn't support calling or returning RECORD Types , So i was thinking of sending a OBJECT type and convert that to a RECORD type,
I appreciate any help with the code or point to the documentation,
thanks

1067: Implicit coercion of a value of type String to an unrelated type

Hi,
I created a webservice based on sql server 2005 with several methods successfully.
I am having headach now just trying to do some simple tests with Flex :-(
I used the "Import WebService", it created some code "generated webservices".
My test method p_SEARCH_NAME_SOUNDEX is based on a sql procedure wich take a varchar (128) as a parameter => NAL_NOM.
I am just trying to debug this function (error at line in red)
       public function searchEntry(name:String):void
            // Register the event listener for the findEntry operation.
            //agenda.addfindEntryEventListener(handleSearchResult);
            myWS.addp_SEARCH_NAME_SOUNDEXEventListener(handleSearchResult);
            // Call the operation if we have a valid name.
            if(name!= null && name.length > 0)
               myWS.p_SEARCH_NAME_SOUNDEX(name);
I got this error message:
067: Implicit coercion of a value of type String to an unrelated type generated.webservices:NAL_NOM_type1.
FLEX has creaetd a type called NAL_NOM_type1 for my class:
* NAL_NOM_type1.as
* This file was auto-generated from WSDL by the Apache Axis2 generator modified by Adobe
* Any change made to this file will be overwritten when the code is re-generated.
package generated.webservices
    import mx.utils.ObjectProxy;
    import flash.utils.ByteArray;
    import mx.rpc.soap.types.*;
     * Wrapper class for a operation required type
    public class NAL_NOM_type1
         * Constructor, initializes the type class
        public function NAL_NOM_type1() {}
        public var varchar:String;public function toString():String
            return varchar.toString();
I tried to do myWS.p_SEARCH_NAME_SOUNDEX(NAL_NOM_type1(name));
and also declared "name" as NAL_NOM_type1... but i still get this error.
This is how it declared my webservice method:
        public function p_SEARCH_NAME_SOUNDEX(nAL_NOM:NAL_NOM_type1):AsyncToken
             var _internal_token:AsyncToken = _baseService.p_SEARCH_NAME_SOUNDEX(nAL_NOM);
            _internal_token.addEventListener("result",_P_SEARCH_NAME_SOUNDEX_populate_results);
            _internal_token.addEventListener("fault",throwFault);
            return _internal_token;
I am even not on the level of assigning the data to my grid... i just want to see how it gets the data first in debug.
Thanks in advance for you help.
kr,
Meta

Thanks _Natasha_
I tried this:
var t = new NAL_NOM_type1();
t.varchar = name;
myWS.p_SEARCH_NAME_SOUNDEX(t);
It passes the 1st step :-) but I get another error now :-/
I think it try to get back NAL_NOM_type1 from the server of course on the WSDL side it know only NAL_NOM
Error: Cannot find definition for type 'http://NABSQL64DEV/::NAL_NOM_type1'
    at mx.rpc.xml::XMLEncoder/encodeType()[C:\autobuild\3.2.0\frameworks\projects\rpc\src\mx\rpc \xml\XMLEncoder.as:1426]
I guess I have to change my constructor type... i am not used to these stuff :-s
is this generating method the best way to access your data with webservices?
the turorials I saw are xml file or array based... is there any link similar to my issue so I can learn better?

FM to convert character type to hexadecimal type

I have to make an object unicode compliant .
in the object the password is created using paskey and bcode.
Bcode contains all alphanumeric or alphabets.
and paskey is numeric.
to create password passkey and bcode are subtracted bit by bit.
now the problem is that i am not able to convert the Bcode to numeric type.
hence at the line where subtraction is starting.
its giving runtime error.
Can anyone help me to convert the alphnumeric chartcters to numeric...hexdecimal type.
Is there any FM or any code , plz tell me.
Its urgent.
Thanks and regards,
Prachi

Prachi,
Check the below FM'S

WSIF string(xml) to (anonymous type)

Hi All,
I have a WSIF service that returns a string value which is an xsd schema defined xml element. Should I leave the response type as a string and transform it in my BPEL to the element? Or should I map the string to the element within the WSIF wsdl and try and return the element itself from the WSIF? Which of the two is the better more efficient design?
Thanks in advance.

Converting string to int

I cannot convert this string to integer.
int tempI = Integer.parseInt("fdcedfbd", 16);
it returns a numberFormatException
but if I do this then there will be no problem.
int tempI = 0xfdcedfbd
Can anybody help me with this? Thank you.

It sounds like the real problem here is that someone is giving you an 8-byte unsigned value represented as a 16-character hexadecimal string, and they want you to convert that into the actual 8 bytes. Are they going to do bit manipulation on it or something?
If you successfully convert it into a long and they then try to do math with it, they'll run into the sign/overflow problems everyone else has been talking about. If they just want to look at the individual bits then it would make sense to do the conversion into a long.
You could do something like this:
private static final String highOrderDigits = "89abcdef";
public long hexToLong(String hex) {
    // Only process exactly 16-digit strings.
    if (hex.length() != 16) {
      throw new IllegalArgumentException("Expect 16-digit hex value");
    boolean overflow = false;
    // Check for most significant digit > 7, which would
    // cause problem for parseLong.
    int highOrderIndex = highOrderDigits.indexOf(hex.charAt(0));
    if (highOrderIndex > -1) {
      // Clear most-significant bit and set overflow flag.
      overflow = true;
      hex = "" + highOrderIndex + hex.substring(1);
    long result = Long.parseLong(hex, 16);
    if (overflow) {
      // Manually set most significant bit in result.
      result |= 0x8000000000000000L;
    return result;
}I more or less tested this and it looks to work.
