Compatible & Incompatible types

Why is that I can assign a integer value to a double variable, but cannot assign a double value to an integer variable? Aren't double and integer compatible types? Isn't there a concept of truncation in java? I searched the net but in vain. I couldn't find the exact answer I was looking for. So I am posting in this forum.
PS: I understand it is not possible to assign an integer to a string since they are incompatible types.

Why is that I can assign a integer value to a double variableBecause it's a widening conversion that doesn't lose any information. See JLS #5.1.2.
but cannot assign a double value to an integer variable?Because it's a narrowing conversion that might lose information. You can do it as long as you write an explicit typecast. See JLS #5.1.3.
Aren't double and integer compatible types?No, see above.
Isn't there a concept of truncation in java?Yes, see above.
@rp0428 I don't see what good asking for the code and the error message does, in a fundamental case like this. It doesn't change the answer, and your own answer (is/isn't) wasn't too inspiring.

ORABPEL-10041 Trying to assign incompatible types

Hi,
I'm developing a BPEL process which takes an input xml file and inserts data into AP interface tables. I used a file adapter to read the input file and used applications adapter to import ap interface tables.
I use the assign activity to assign the number value from my xml file to the invoice_id column in the ap_invoices_interface column. I get the following warning. Can anyone please tell me how do I fix this. I have BPEL 10.1.2.2 installed.
Warning(29):
[Error ORABPEL-10041]: Trying to assign incompatible types
[Description]: in line 29 of "C:\OraBPELPM_1\integration\jdev\jdev\mywork\Workspace1\BPELProcess_TestInsert\BPELProcess_TestInsert.bpel", <from> value type "{http://www.w3.org/2001/XMLSchema}string" is not compatible with <to> value type "{http://www.w3.org/2001/XMLSchema}long".
[Potential fix]: Please make sure that the return value of from-spec query is compatible with the to-spec query.
Thanks

This is just a warning so it does not mean that your process will fail, e.g. string to decimal may work for the string holds a number, but will fail if it has a string.
So if you know the data you can safely ignore, otherwise you will have to do some transofrmation within an assign.

Incompatible types error on a for loop

Hi. I am in the middle of making a program and a decided to make a print statment to check to make sure everything was organized as it should be and I got an incompatible types error for the line where I start my for loop - for (index = 0 ...) etc. Since everything is an int, I'm not sure how they're not compatible with each other.. thoughts? here's my code so far, thanks

Well... can anyone help with this? Or at least some explanations why adding second generic generates this problem?

The problem is in the recursion, not in the second type argument. If you changed your first interface from
    public interface I<T extends I<?>> {} to
    public interface I<T extends I<T>> {} you would run into the same error message. For sake of clarity let's discuss the issue using your first example in a slightly simplified form:
    public interface I<T extends I<T>> {}
    public class Z<E>
      public I<? extends I<E>> m1 ()
        return m2();
        /* error: incompatible types
           found   : I<capture of ? extends I<E>>
           required: I<? extends I<E>>
           return m2();
                    ^
      protected I<? extends I<E>> m2 ()
      { return null; }
    }The error message is not awfully helpful, because the "E" is different in both types.
Method m2 returns a reference of type I<capture of ? extends I<E>>, where E extends I<capture of ? extends I<E>>, that is, it returns a concrete instantiation of the interface, namely I<SomeType> with a type that extends I<SomeType> with a type that extends ... continued recursively.
On the other hand, method m1 is supposed to return a reference of type I<? extends I<E>>, where E extends I<? extends I<E>>, that is, it returns a wildcard instantiation of the interface, namely I<? extends I<SomeType>> with a type that extends I<? extends I<SomeType>> with a type that extends ... continued recursively.
And here is the point: The first construct leads to a concrete instantiation like a List<List<List<String>>>. The second construct lead to a recursive wildcard instantiation like List<? extends List<? extends List<?>>>. As soon as the wildcard appears on a nested level, the types are no longer compatible.
It's like assigning a List<List<String>> to a List<List<?>>. It's not permitted because the first is a list of string-lists and the second is a list of mixed-lists. You cannot assign one to the other.
In your example, changing
    public interface I2<Tx, T extends I2<Tx, ?>> to
    public interface I2<Tx, T extends I2<?, ?>>might do the trick.
(As usual, ignore the annoying additional angle brackets.)

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.

Incompatible types with generics problem

Hi,
I get a mysterious compiler error:

found : tests.Store<T>
required: tests.Store<T>
return store;

    class B<T extends Supply<T>> {
        public Store<T> getStore(){
            return store;                         <-- compiler error!
}Any help would be greatly appreciated.
Edited by: farcat on Jan 13, 2009 1:23 PM

Note that the type parameter T used to define class B is not the T used to define class A. What you wrote can be more clearly written:
class Supply<T extends Supply<T>>{}
class Store<T extends Supply<T>>{ }
class A<T extends Supply<T>>{
    private Store<T> store;
    class B<U extends Supply<U>> {
        public Store<U> getStore(){
            return store;
}Which produces the more readable error message:
A.java:10: incompatible types
found   : Store<T>
required: Store<U>
            return store;B, being a nested, non-static class is already parameterized by T:
class Supply<T extends Supply<T>>{}
class Store<T extends Supply<T>>{ }
class A<T extends Supply<T>>{
    private Store<T> store;
    class B {
        public Store<T> getStore(){
            return store;
}

Incompatible types in case statement

I'm getting incompatible types inside this case statement :
inString = s_in.readUTF();
            switch (inString.substring(1,3))
                case nam:
                    ChatClient.nameArea.append(inString);
                    break;
                case txt:
                    ChatClient.chatArea.append( "\n >>>" + inString );
                    break;
            }If you want, or need to see more or all of the code in this class, just ask.

This is because you can't use Strings within a switch statement. Use if statements instead.

[SOLVED] XSD simpleType trying to assign incompatible types

Hi all!
I have a big XSD schema with complex and simple types defined. One of the simple types looks like this (string with min and max length defined):
     <xsd:simpleType name="MySimpleType">
          <xsd:restriction base="xsd:string">
               <xsd:minLength value="1" />
               <xsd:maxLength value="36" />
          </xsd:restriction>
     </xsd:simpleType>I assign (copy operation) a string variable to an element of this type. When I compile i get the trying to assign incompatible types warning. I know it's just a warning but I'd like to solve it. I thought I can create a variable of the same type, but I can't (if I try to define message type only the complex type from XSD are displayed).
Is there a way to get rid of this warning?
Thanks

instead of using a variable assignment use the expression builder to construct the 'bpws:getVariableData() equivalent of the variable assignment. The warning will no longer exist.

Incompatible types

I get the following error message:

...and it is associated with the piece of code below. I do not understand in what way the �G� and �B� are incompatible types with sa[3] which is supposed to hold strings.
StringTokenizer st=new StringTokenizer(s, �*�);
String[] sa=new String[st.countTokens()]; int i=0;
while(st.hasMoreTokens())
sa=st.nextToken();

What is the problem here?

If you are using only 1-character strings, then you can do:
   switch (sa[3].charAt(0)) //sa[3] contains customer type
      case 'B': // ...
      case 'G': // ...
      // etc.
   }

Incompatible type error

I am receiving the following errors:
incompatible types
found: int
required: boolean
if (accessCode = 8345)
if (accessCode = 55875)
if (accessCode = 999909)
I do not understand why I am getting the errors. accessCode is of type int.
Thanks in advance for any input.
int accessCode = Integer.parseInt( String.valueOf(
securityCodeJPasswordField.getPassword() ) );
     int code;
     if (accessCode >= 1645 && accessCode <= 1689)
         code = 1;
     else
     if (accessCode = 8345)
            code = 2;
     else
     if (accessCode = 55875)
         code = 3;
     else
     if (accessCode = 999898)
         code = 4;
     else
     if (accessCode >= 1000006 && accessCode <= 1000008)
         code = 5;
     else
     if (accessCode < 1000)
         code = 6;
     else
                    code = accessCode;

Thanks !! I am stuck in the coding syntax that I use in my job: SAS

Incompatible Types... NOT!

Why am I getting incompatible types in this method?
C:\jdk1.3\src\CalcBusinessDays.java:53: incompatible types
found : java.util.Date
required: Date
          Date covDate = sdf.parse(dt, pos);^ <-- carat is at end of line
     public Date dateConvert(String dt) {
          SimpleDateFormat sdf = new SimpleDateFormat("mm/dd/yyyy");
          ParsePosition pos = new ParsePosition(0);
          Date covDate = sdf.parse(dt, pos);
          return covDate;
     }     //dateConvert
Thanks in advance.

Actually I'm in Hartford, CT, where NJ sends its rain! I used to live in Staten Island which is close to NJ as you know. Also worked in Parsippany for a while.
I think "Date" needs to be changed to "java.util.Date" in three places. See comments below where changes are marked. I could not compile or test because I don't have Domino / Notes.
By the way, in case you get similar problems with another class (Calendar?), I believe that the lotus.domino classes are AgentBase, AgentContext, Session and DateTime. The others should be standard Java classes. Good Luck.

Error in Parser.fx file "incompatible types found   : java.util.Properties"

Hi,
In parser file "Parser.fx",
public-read def PROPERTIES_PARSER = StreamParser {
override public function parse(input : java.io.InputStream) : RecordSet {
var props = javafx.util.Properties {};
props.load(input);
input.close();
MemoryRecordSet {
records: [
MapRecord {
fields: props
due to under line portion an error is appearing:
"incompatible types
found : javafx.util.Properties
required: java.util.Map
fields: props".
Please suggest some solution.
Thanks in advance.
regards,
Choudhary Nafees Ahmed
