Converting type INT to type String...possible?
Hi
I basically have a stored string that I want to add numbers to, like adding a phone numbers digits to eachother or a calculators numbers to eachother in seperate instances. Is this possible?
So say I ask the user to input a number (single), can this then be added to the string field and then perhaps looped (dont tell me how to do that - I will try that myself) to create a string of 10 or more numbers?
Thanks for any help
Thanks but I have to start with a param of INT before
adding it to the string, and I cant seem to do this
with casting (String) FIELDNAME - I get the
Inconvertible types error[url http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Integer.html#toString(int)]Integer.toString()

How do I convert an int to a String?
You can also use any of these methods if you need to get more complicated:
Integer.toString(int i)
Integer.toBinaryString(int i)
Integer.toHexString(int i)
Integer.toOctalString(int i)
Integer.toString(int i, int radix) -
i want to know how to convert an int to a string .
I have tried toString() but it says can't dereference an int.
any ideas ????
thanksWhat I mean by the object being null is, say for example, you have the following method:
public String combine(Object o1, Object o2){
return o1.toString() + o2.toString();
}This method will throw a NullPointerException if either or both o1 and/or o2 are null. If you use it like so:
public String combine(Object o1, Object o2){
return String.valueOf(o1) + String.valueOf(o2);
}This will always work. (I know someone out there would say that this would return a String like "nullnull" if both are null, and so forth and so on, but hey, you get my drift.) I'm also not saying the you can't not check if either o1 or o2 is null before proceeding, so the following also works:
public String combine(Object o1, Object o2){
String s = null; // I'm using this instead of StringBuffer for
// simplicity's sake so don't get this wrong
if (o1 != null){
s = o1.toString();
if (o2 != null){
s += o2.toString();
return s;
}As you can see, there's no right or wrong way in programming as long as you achieve the result. The only thing that would matter is how clean your code is, how efficient your code is, and how maintainable your code is. -
How to convert an int array to string array?
Hi,
Can anyone please help me with this question?
int number={4,6,45,3,2,77};
I like to convert this into a list and sort
List mylist = Arrays.asList(number);
Collections.sort(mylist);
But first I need to convert the int array to String array.
Please advise. Thanks.If you want to convert your int array to a String array, you have no choice but doing a conversion element by element in a for loop.
However, if the sort method doesn't behave as desired, you can use the one with 2 parameters, the second parameter being a comparator class.
Check the javadoc for more information : http://java.sun.com/j2se/1.3/docs/api/java/util/Collections.html

How to convert an int variable into String type
hi everybody
i want to know how to convert an interger variable into string variable
i have to implement a code which goes like this
Chioce ch;
for(int i=0;i<32;i++)
// here i need a code to convert the int variable i into a string variable
ch.add(String variable);
how do i convert that int variable i into a String type variable??
can anyone help me?Different methods:
int a;
string s=a+"";or
String.valueOf(int) is the better option because Int.toString() generated an intermediate object to get the endresult

Convert TYPE string to TYPE p in a UNICODE system
Hi-
I've got a string that contains an amount and I want to convert it into a TYPE p in my program to store as a proper amount in the database.
I can't do a simple move or use FMs like HMRC_AMOUNT_STRING_CONVERT as I am in a Unicode system and it errors if I try these.
How can I do it.
Example.
parameters p_amount type string.
start-of-selection.
data l_amount TYPE p decimals 2.
MOVE p_amount TO l_amount.
=>compile error.Hi Tristan.....
IN PARAMETERS we ca have only have predefined data
The data types valid for parameters include The built-in ABAP types c, d, i, n, p, t, and x
You cannot use data type F, references and aggregate types.
But you are using type STRING which is not allowed.
so you are getting a compiler error.

Hi,
when i try to do the following its an error
int totalmarks;
String Totalmarks;
Totalmarks = totalmarks.toString();
could any one tell me how to do it correctly
Thank youA lot of alternatives, but you can't do new String(int..).
1. Integer.toString(totalmarks)
2. String.valueOf(totalmarks) will call Integer.toString(totalmarks)
3. ""+totalmarks will use the StringBuffer and append "" and totalmarks which again will call String.valueOf(totalmarks) which again will call Integer.toString(totalmarks) -
Trying to convert a int back to a textfield - help
Okay this is what I want. I want to type a number in a TextField and double it.... So lets say I type in 10, it will output 20.. But I cant seem to get it to work. The integer won't change it back to a textfield usable text thing .. any help? And yes, i'll admit, its for school, not really for marks, but just to learn.. Theres like 10 of them. And I've been trying to get it to work for awhile, and I ain't asking for coding, or cheating. I'm just asking for help :)
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Myname extends Applet implements ActionListener
Button pressMe = new Button("Enter a number");
TextField answer = new TextField(10);
Font bigfont = new Font("TimesRoman", Font.ITALIC,24);
public void init()
add(pressMe);
add(answer);
answer.requestFocus();
pressMe.addActionListener(this);
public void actionPerformed(ActionEvent thisEvent)
int doubleamount = (new Integer(answer.getText())).intValue();
int doubleamount2 = doubleamount + doubleamount;
answer.setText(doubleamonut2);
invalidate();
validate();
Thats what I haveYou need a String.valueOf (doubleamount2)to convert your int to a String, and you don't need
the revalidate ().
Kind regards,
LeviYeah, Levi is correct. :-) -
Hi All,
I am reading notepads files and inserting data in sql tables from the notepad-
while performing sql bulk copy on this line it throws exception - "bulkcopy.WriteToServer(dt); -"data type related(mentioned in subject )".
Please go through my logic and tell me what to change to avoid this error -
public void Main()

string[] filePaths = Directory.GetFiles(@"C:\Users\jainruc\Desktop\Sudhanshu\master_db\Archive\test\content_insert\");
for (int k = 0; k < filePaths.Length; k++)
string[] lines = System.IO.File.ReadAllLines(filePaths[k]);
//table name needs to extract after = sign
string[] pathArr = filePaths[0].Split('\\');
string tablename = pathArr[9].Split('.')[0];
DataTable dt = new DataTable(tablename);

string[] arrColumns = lines[1].Split(new char[] { '|' });

for (int i = 2; i < lines.Length; i++)
string[] columnsvals = lines[i].Split(new char[] { '|' });
DataRow dr = dt.NewRow();

SqlBulkCopy bulkcopy = new SqlBulkCopy(conn);
bulkcopy.DestinationTableName = dt.TableName;
bulkcopy.WriteToServer(dt);
conn.Close();
Issue 1:-
I am reading notepad: getting all column and values in my data table now while inserting for date and time or integer field i need to do explicit conversion how to write for specific column before bulkcopy.WriteToServer(dt);
Issue 2:- Notepad does not contains all columns nor in specific sequence in that case i can add few column ehich i am doing now but the issue is now data table will add my columns + notepad columns and while inserting how to assign in perticular colums?
sudhanshu sharma Do good and cast it into river :)Hi,
I think you'll have to do an explicit column mapping if they are not in exact sequence in both source and destination.
Have a look at this link:
https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopycolumnmapping(v=vs.110).aspx
Good Luck!

The workaround is to add a custom converter class to your ViewController project like this
package oow2008.view;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.convert.Converter;
import javax.faces.convert.ConverterException;
import oracle.jbo.domain.ClobDomain;
import oracle.jbo.domain.DataCreationException;
public class ClobConverter implements Converter {
public Object getAsObject(FacesContext facesContext,
UIComponent uIComponent,
String string) {
try {
return string != null ? new ClobDomain(string) : null;
} catch (DataCreationException dce) {
dce.setAppendCodes(false);
FacesMessage fm =
new FacesMessage(FacesMessage.SEVERITY_ERROR,
"Invalid Clob Value",
dce.getMessage());
throw new ConverterException(fm);
public String getAsString(FacesContext facesContext,
UIComponent uIComponent,
Object object) {
return object != null ?
object.toString() :
null;
}then to register the converter in faces-config.xml like this
<faces-config version="1.2" xmlns="http://java.sun.com/xml/ns/javaee">
<application>
<default-render-kit-id>oracle.adf.rich</default-render-kit-id>
</application>
<converter>
<converter-id>clobConverter</converter-id>
<converter-class>oow2008.view.ClobConverter</converter-class>
</converter>
</faces-config>then reference this converter in the field for the ClobDomain value like this
<af:inputText value="#{bindings.Description.inputValue}"
label="#{bindings.Description.hints.label}"
required="#{bindings.Description.hints.mandatory}"
columns="40"
maximumLength="#{bindings.Description.hints.precision}"

How do I convert a Variant of type=String to G data? (LV 5.1.1)
I've tried to return a string in the Variant return of a VB function in a DLL. (I want to do this so that I can retain the interface and thus binary compatibility in the DLL.)
When I use the DLL function in LabVIEW 5.1.1 I
get an error in the call library function call (returning). It looks like there is a way to handle this in v 6.0 but I have to use 5.1.1 for this application. Is there a way for LV 5.1.1 to handle a Variant containing a string?
Thanks
Dave Karon
Concepts NRECHi Dave,
you can use the type conversion function located under advanced -> data
manipulation to convert the variant into a string.

but after that I got an error that " Object reference not set to an instance of an object".Why this type of error occurs??
Still confused about how you define variable "array[0]".
Based on your error information, because your DC is null. As I said before, DC is an int[]. You must assign an array to DC.
int[] array = new int[] { 2, 43 };
test s = new test();
s.DC = array;
s.DC[0] = 12;//It works fine

Thanks in advance
B.VenkatesanThe error message indicates the problem fairly clearly. _feed_list is defined as a ComboBox in your first line of code. You are passing that as an argument in your populate(_feed_list) line of code. However, the populate function is expecting an XMLList object to be passed, not a ComboBox.
You probably really mean to be using...
populate(feed_items);
since that is the only XMLList to be found
