Recompile with -Xlint:unchecked for details???

hi friends ,
im using jdk-6-windows-i586. and apache-tomcat-5.5.26.
In development phase i got the following error while compiling
BeerExpert.java file. This is my model.
Note: BeerExpert.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
But the class file is created. Is this any type of error or just warning msg.
What is the meaning of this and what to do for it.
Then I recompile the file with javac -Xlint BeerExpert.java or javac -Xlint:unchecked BeerExpert.java
and the warning msg. appered as-
BeerExpert.java:9: warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.List
brands.add("Jack Amber");
error pos::: ^ error or warning position pointed by compiler
4 warnings
my source code is-
package com.example.model;
import java.util.*;
public class BeerExpert {
public List getBrands(String color) {
List brands = new ArrayList();
if(color.equals("amber")) {
brands.add("Jack Amber");
brands.add("Red Moose");
else {
brands.add("Jail Pale Ale");
brands.add("Gout Stout");
return(brands);
Any suggestions what to do? Please..
Thanx in advance.

hi i have the same problem but my compiler is different
it says note: stream.java uses or overrides depricated API
recompile with XLINT:deprication for details

Compliation Error: Recompile with -Xlint:unchecked for details

I am new to Java and am working through Sams Teach Yourself Java2 book. One of the examples gave me a compilation error. The problem code follows:
C:\Java_Work\com\ramyam\ecommerce>java c Storefront.java
Note: Storefront.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
package com.ramyam.ecommerce;
import java.util.*;
public class Storefront {
     private LinkedList catalog = new LinkedList();
     public void addItem(String id, String name, String price, String quant) {
          Item it = new Item(id, name, price, quant);
          catalog.add(it);
     public Item getItem(int i) {
          return (Item)catalog.get(i);
     public int getSize() {
          return catalog.size();
     public void sort() {
          Collections.sort(catalog);
}I think it has something to do with the collections class being outdated. Does anyone have any idea how to fix this?
Thanks in advance,
georgina

The book probably was published before Java had Generics. You can do as the error message says and recompile with the Xlint:unchecked option. Basically, you need to specify the type of objects you are putting into the LinkedList, something like      private LinkedList<Item> catalog = new LinkedList<Item>();This may cause you other errors.........

hi, i'm new in java
i had tried to write one simple java applet, but
when
i compiled this message was come out:
c:> javac applet1.java
Note:applet1.java uses or overrides a depreciated
API
Note: recompile with -Xlint :deprecation for detailsThis is a warning that means that a class or method that you are using in your code is deprecated. A class or a method can be deprecated for several reasons:
e.g. the class/method could contain an error which makes the code unstable, the class/method could be written in a non standard way, the class/method could have been replaced by a more efficient/better/improved class/method
The deprecation message is only a warning. The code will compile even when deprecated. However, most code is deprecated for a reason, so you should try to find out what the substitution is (if one exists).
To find out what the problem is, the java compiler suggests you recompile using -Xlint: deprecation.
So instead of compiling using
javac YourClass.java
type
javac YourClass.java -Xlint:deprecation
You should get a message such as:
C:\Jenjava\Test\PacMan.java:56: warning: [deprecation] isFocusTraversable() in java.awt.Component has been deprecated
public boolean isFocusTraversable(){
Look up the offending method in the API at http://java.sun.com/j2se/1.5.0/docs/api/
It says:
isFocusTraversable
@Deprecated
public boolean isFocusTraversable()Deprecated. As of 1.4, replaced by isFocusable().
So, to get rid of the warning (and use the current method) we replace the isFocusTraversable() with isFocusable().
Make sense?

-Xlint:unchecked for details

Note: C:\Documents and Settings\voonkt\Desktop\Work\Project (06-01-05)\SendComponent.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
What kind of warning is this? What can I do to resolve it?

First, I'm going to assume that you're compiling with java 1.5/ In that case, the warning indicates that not all of your code is typesafed. That is to say the java wants you to use generics in your source code. Compiling with the -Xlint flag will cause javac to show you where it thinks you should be using generics.

User defined function in PI 7.1 compilation error "Recompile with -Xlint"

Hi All,
I have a user defined function in PI 7.1 .,which is throwing the following error.
Do i need to add any import statements like "import java.lang.String" in the beginning.
It is unable to recognize the String methods used in the user defined function.

container.getParameter() returns Object, not String.
try following:

You use "-Xlint:unchecked" as one of your command-line options. So instead of
javac Thingy.javayou do this instead:
javac -Xlint:unchecked Thingy.javaOf course if you already have several command-line options when you do your compiling, then you just need one more.

Compiling via XML file with Xlint:unchecked, JDK 1.5.0_05

compiling 1.4.2_04 code with 1.5.0_05 using an Ant/Tomcat environment and get the following Notes:
[javac] Note: Some input files use unchecked or unsafe operations.
[javac] Note: Recompile with -Xlint:unchecked for details.
added this to my XML file to try to compile with unchecked:
<property name="compile.unchecked" value="true"/> 
<target name="compile">
<javac srcdir="${source.home}"
destdir="${deploy.home}"
debug="${compile.debug}"
deprecation="${compile.deprecation}"
unchecked="${compile.unchecked}" >
optimize="${compile.optimize}"/>
</target>
Now I get this build error:
BUILD FAILED
file:C:/.../my_Build.xml:71: The <javac> task doesn't support the "unchecked" attribute.
This seems strange. Am I using unchecked incorrectly? This same code has <property name="compile.deprecation" value="true"/>, which functions and gives me more info on a few deprecated methods in the code, so I followed the same syntax.
Any suggestions would be appreciated. Thanks

Thank you - that did it.
I am new to Java and am wondering if you can give me any clue as to what an "unchecked call" means? How do I go about making it a "checked call"? If it is a warning and not an error, does it really matter? Can you point me to a good reference (online or book)?
This is the info I got on the xml file when I compiled with unchecked:
warning: [unchecked] unchecked call to addElement(E) as a member of the raw type java.util.Vector
[javac] searchThreads.addElement(temp);
This is the code it is looking at (mostly comments, but didn't want to strip them out):
// Create a vector to hold all of the search threads. 1000 should be more than enough.
Vector searchThreads = new Vector(1000);
// Start spawning search threads until the server socket is found, or until 1000 threads have been created.
while ((searchThreads.size() < 1000) && !found)
// We need to check to see if we've connected to the right server by reading what the server sent back to us.
//If it sent back the string "TM Server", then we're in the right place. If we get anything else, or we get nothing, then we need to keep looking.
// We spawn a thread for each socket to save time, and as soon as one of the threads finds the right socket, it sets a flag telling us to stop looking.
// Create and start the search thread
PortFinder temp = new PortFinder(tmHostName, startPort);
temp.start();
// Add the search thread to the vector THIS IS THE UNCHECKED CALL
searchThreads.addElement(temp);
// Increment to the next port before looping
startPort++;
Thanks

Recompile with -Xlint:deprecation, whaat is it?

Hi, all!
When I'm compiling a prgm, I get this note: Recompile with Xlint:deprecation for details.
buttons.java uses or overrides a deprecated API.
I don't know what is it, and what does it prompt me to do.
Your help is highly appreciated.

An API you are using has been deprecated ^1^ (should no longer be used, for example Thread.stop ^2^ has been depricated as it is not safe to use).
Compiling with "Xlint:deprecation" will tell you what you are using, you can then look that up in the API to tell you what you need to do instead.

recompile with -Xlint(any one know what this is?)
Is it the JDK version i'm using ? First i thought it's a security issue.As in windows is not letting me access the serial ports.
I checked with device manager.My serial ports are open. Ichanged my BIOS settings as well..
(I read inputs from parallel port.But i dont use the comm api for that)
I have installed the rxtx gnu.io package as well..
Tried import gnu.io.* instead of javax.comm.*; still the same compilatiion error!!!
Thanks in advance
goodnews:-(

It is basically a warning (not an error) that the compiler gives you to let you know that you are using a raw type where Java now supports generic types.
For example, in the code you use:
HashMap where you can use HashMap<String,String> to let the compiler know that you intend inserting Strings for both the key and the value. The former is considered to be unsafe because the compiler cannot control what is inserted into the HashMap while in the latter case it can ensure that only Strings are used for both keys and values.
The compiler is also letting you know that if you want to see the details of these "unsafe" operations you can use the -Xlint:unchecked option when compiling and the compiler will show you exactly which lines contain the code that is generating the warning. So to compile with this option you would use javac -Xlint:unchecked ClassToCompile.

Xlint:unchecked compilation error?

Hello,
when i try to compile the following code as part of a servlet application , the following Xlint:unchecked error occurs.I cant understand since I am using jdk1.5 or is it referring to generics in collections?if so could anyone pls reply how to fix it.Thanks in advance.

Set ojdeploy to include -Xlint:unchecked in it's compile

Having a very weird issue with ojdeploy.
The project compiles without errors via jDeveloper, but when I compile it through ANT using ojdeploy I get the following

How do I set -Xlint:unchecked for ojdeploy? (if that is even possible).

Hi DoctorZ,
in a VI is
a) the relative path if on the same drive,
b) the absolut path if on another drive,
c) the name only if the subVI is in vi.lib, user.lib or instr.lib
to all subVIs stored. So if your search path does not include and the subVI will always be found. The search path is only used when to load a VI that has moved from its original path or is a top level VI.
I have no place found to turn off this behavior.
I find this behavior is good. So we need not to maintain a list of search paths for each project since not all projects have the same directory layout. A lot of us work on more than one project within two weeks and we use often a lot of subdirs.
Also we maintain the project in a project directory. Each dev
eloper makes a local copy of the project. All paths are now correct and the developer can do his work. If he finished he closes LV, copies the VIs back to the project directory and can now open the project again from the project directory. And all the paths are correct again.
It is neccessary to close LV, so it forgets all the paths which are collected from the time when it was started.

-Xlint: Unchecked Error Explanation

I have done a compile with -Xlint: Unchecked and i have got back the following results.
[Unchecked] Unchecked Conversion
[Unchecked] Unchecked Method invocation: <T>sort[java.util.List<T>,java.util.Comparator<? super T>in java.util.Collections is applied to [java.util.ArrayList<Album>, java.util.Comparator]It relates to

     if( !(anotherAlbum instanceof Album) ) //comparing
               throw new ClassCastException("Instance of Album expected"); //exception handling
               int anotherAlbumArtistName = ((Album)anotherAlbum).getID(); //standard sort on my getID() method
               return this.noOfTracks - anotherAlbumArtistName;   //returns the inputs in sorted accesending order
public static Comparator NameComparator = new Comparator() //creating a new name comparator object which is integrated
                                                          //within my comparable Album.

            String make1 = ((Album)album).getCD().toUpperCase(); //comparison on my cd names
            String make2 = ((Album)anotherAlbum).getCD().toUpperCase();
            return make1.compareTo(make2);   //returning cd name sorted from a-z
}Does anyone know what is wrong?

You've got two different things going on here. You're mixing Comparators and Comparables.
If Album is to be Comparable, then that means it has a "natural" order, and you'd declare it as public class Album impelements Comparable<Album>[/ode], and you'd provide a compareTo(Album) method so that it can be compared to other albums, and a list of Albums can be sorted without providing an external Comparator class.
If you just want Comparators--external classes that order pairs of Albums, then don't make Album Comparable, and don't implement compareTo.
Or, you can do both.

Function module for detailes description of Order and long text in task

Hello gurus,
please help me with Function module for detaile description of Order and long text in task list(operation Tab)?
regards,
YK

Hi,
You should be able to read the Order short text directly from table AUFK. The Order long text or task list long text can be read by using FM "Read_text". Use Goto> Header on every long text screen to identify the parameters that need to be passed hen using this FM.
