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

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. -

You can also use any of these methods if you need to get more complicated:

Integer.toString(int i, int radix) -

How to convert an int variable into Number
Hi all,
I am using Jdeveloper 11.1.1.2
When I insert a row in a entity object I want to create another row in another entity object, but when I am setting the attribute for the new row I have a problem.
Here is the code:
int a = EO1Impl.paramA;
NameEO2Impl.setAttribute("Attribute1", a);
The error is that variable a is an int, while Attribute1 is a Number.
How can convert an int to a Number.
Thank you.Andrea9,
If a, as you say is an int, and assuming you mean an oracle.jbo.domain.Number,
NameEO2Impl.setAttribute("Attribute1", new oracle.jbo.domain.Number(a));works just fine.

Cast Object Array to String Array.
When I try to cast an object array to string array an exception is thrown. How do I go about doing it?
Vector temp = new Vector();
Object[] array = temp.toArray();
String[] nonterms;
nonterms = (String[])array;
Thanks,
AllyTry this
import java.util.Vector;
public class Test
public static void main(String args[]) throws Exception
Vector v = new Vector();
v.add("a");
v.add("b");
v.add("c");
Object[] terms = v.toArray();
for(int i = 0; i < terms.length; i++)
System.out.println((String)terms);

How do I make an array of String Arrays, not knowing how big the array will be
or how big any of the arrays it contains will be at the time I create it?The size of an array is not dynamic, i.e. if you use an array, you must know its size at the time you create it.
Use one of the collection classes (like java.util.Vector or one of the implementation classes of java.util.List).

How to convert an int number to a byte array, and how to convert back?
Hello, everybody,
Just as the topic, if I have an int number(which should have 32-bit, or 4-byte), how can I convert it into a byte array. And also, how to convert it back.
Thank you in advance!Alternatively you can use ByteBuffers to do this work for you
// to a Byte Array
int originalInt =...;
ByteBuffer myBuffer = ByteBuffer.allocate(4);
myBuffer.putInt( originalInt );
byte myArray[] = myBuffer.array();
// and back to an int
ByteBuffer myOtherBuffer = ByteBuffer.wrap(myArray);
int finalInt = myOtherBuffer.getInt(); -

How to convert a "text variable" to String with plugin
Hello,
I am currently developing a InDesign (CS5) plugin, where I need to manipulate text variable.
From the plugin I want to convert the "text variable" to string (in principle I should use the method "VariableToString (..)" of "ITextVariable")"
My problem is, how to find the text varial from its name (I think I should use the method "FindLocationsUsed(..)" of "ITextVariableSuite") and then convert it to String
I don't know how to use interfaces ITextVariable and ITextVariableSuite
Plugin implemented in C++ language

SIMPLE QUESTION! converting an Enumeration to a String array;
Enumeration e=request.getParameterNames();
i have an enumeration that contains some String objects
how can i convert it to a String array?
thanks a lot.String str = null;
List list = new ArrayList();
while(e.hasMoreElements()) {
str = (String)e.nextElement();
list.add(str);
String[] strArray = (String[]) list.toArray();
Disclaimer: Code not tested; use at your own
risk ;)Taht piece of code will probably throw class cast exception at the line:
String[] strArray = (String[]) list.toArray();The array returned is an object array. You should use:
String[] strArray = (String[]) list.toArray(new String[list.size()]);That methods returns an array of the same type as the argument.
