Incompatible types (Generics)

Can someone explain me please the following message I've got when trying to compile a file?
incompatible types
found : java.util.Iterator<E1>
required: java.util.Iterator<E1>
If the types are identical, how can they be incompatible???!!!
Thanks.

Hello,
I am stuck, I have a compilation probem. I am trying to compile my torque init class, and it gave an error message says that incompatible types. I am using Vector package to check the index of an element in the array. But the compiler found List instead of vector. Can you please tell me what's wrong.

Incompatible types with generics problem

Hi,
I get a mysterious compiler error:
C:\Documents and Settings\Eigenaar\Mijn documenten\NetBeansProjects\Tests\src\tests\genericstest.java:26: incompatible types
found : tests.Store<T>
required: tests.Store<T>
return store;
1 error
BUILD FAILED (total time: 0 seconds)
in the following code:
class Supply<T extends Supply<T>>{}
class Store<T extends Supply<T>>{ }
class A<T extends Supply<T>>{
    private Store<T> 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;
}

Problem with incompatible types

Can you help me out where the problem is? The Child extends the Iterator<GenericTypeTest> so why the assignment doesn`t work? Thank you in advance
class GenericTypeTest implements Iterator<GenericTypeTest> {
    public GenericTypeTest() {
        Child a = null;
        Iterator<GenericTypeTest> b = null;
        b = a;
        Set<Child> sa = null;
        Set<Iterator<GenericTypeTest>> sb = null;
        sb = sa; // HERE: COMPILATION PROBLEM
        // (Incompatible types: found: Set<Child> required: Set<Iterator<GenericTypeTest>>)
    public boolean hasNext() {
        return false;
    public GenericTypeTest next() {
        return null;
    public void remove() {

You can only assign from a subtype to a supertype. And the subtype/supertype relationship for generic types isn't what you think it is. Read this FAQ entry for more information, especially the part around the sentence "The prerequisite is that at least one of the involved type arguments is a wildcard."

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.)

With just these generic error messages being present, this has been difficult to diagnose. Some research has yielded possible resolutions of the Event Viewer log being full, .NET corruption, missing registry entries, but none of those seem to be the issue
(Event Viewer logs cleared, Analysis services is working on the same physical servers in a different cluster, and the registry entries was only a supported issue for SQL Server 2008 and 2008 R2).
Any help would be greatly appreciated.

Bring up Configuration Manager, look at binary path for SSAS. Make sure BOTH folders exist. Sometimes with failovers mappings get screwed up.

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 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.

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

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;

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?

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,
