Color2.java:89: missing method body, or declare abstract

I am creating a color chooser applet but I keep receiving this error please help me to resolve this as my heads wrecked.
Here is my code:
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class Color2 extends Applet implements AdjustmentListener, ActionListener
          Scrollbar redbar, grebar, blubar;
          TextField rfield, gfield, bfield;
          myColorSquare cSquare = new myColorSquare();
     public void init()
          cSquare.setSize(100,100);
          this.add(cSquare);
          Panel n= new Panel(new GridLayout(3,3));
          n.add(new Label("Red (0-255)"));
          this.redbar = new Scrollbar(Scrollbar.HORIZONTAL,0,10,0,265);
          this.redbar.addAdjustmentListener(this);
          n.add(redbar);

          this.cSquare.updateColor(aColor);
     public void adjustmentValueChanger(AdjustmentEvent e)
          this.updateColor();
     public void ActionPerformed(ActionEvent e)
               if (e.getSource().equals(this.rfield))
                    int red = new Integer(this.rfield.getText()).intValue();
                    this.redbar.setValue(red);

                    int green = new Integer(this.gfield.getText()).intValue();
                    this.grebar.setValue(green);
               this.updateColor();
          class myColorSquare extends Canvas
          Color c = Color.black;
          public void paint(Graphics g);
                    g.setColor(this.c);
                    g.fillRect(0,0,this.getSize().width, this.getSize().height);
          public void updateColor(Color v)
                    this.c = v;
                    this.repaint();

What happens if:
public void adjustmentValueChanger(AdjustmentEvent e)
is changed to:
public void adjustmentValueChanged(AdjustmentEvent e)

Missing method body or declare abstract error

Hi!
I have been working on this simple Java 1.3.1 program for three days now and cannot figure out what I am doing wrong. If anyone has done the "Building an Application" tutorial in the New to Java Programming Center, you might recognize the code. I am trying to set up a frame with panels first using the BorderLayout and then the FlowLayout within each section of the BorderLayout. It will have textfields and checkboxes. I am working on the code to retrieve the user input from the text boxes and also to determine which checkbox the user has checked. Here is my code: (ignore my irrelivent comments!)

//This method gathers the input text supplied by the user from five text fields on the Current
//Purchase tab of the tabbed pane of the MPGLog.java program. The way it gathers the text

//a text file called textinput.txt.

I have looked this error up in three different places but the solutions do not apply to what I am trying to accomplish.
Any help would be greatly appreciated!! Thanks!

Geesh! If I had a hammer I would be hitting myself over the head with it right now!!! What an obviously DUMB newbie mistake!!!
Thanks so much for not making me feel stupid! :-)

Error message "missing method body, or declare abstract"

This is my test driver. Does anyone know why it is not working?
public class TestInfo
   public static void main(String args[])
          Info results = new Info();
          printInfo();
     public static String printInfo();
          System.out.println(" The Diameter is: " + results.diam
          + " The Circumference is: " + results.circum
          + " The Area is: " + results.area);
}The error message I get is: missing method body, or declare abstract
The print block has to be a separate method. The print block works when I put it in main. When it is in a separate method and I call it in main it doesn't work

You have an extraneous semi-colon after printInfo. This tells the compiler that that's all there is for that method, which only makes sense if it's an abstract method. It sees the block after the semicolon, but it thinks it's an initializer. So it wants you to either declare it abstract, or give it a method body.
Just remove that semicolon and you're fine.

Missing method body or declare abstract...

Hi There,
Im working on an assignment that works with the math class and performs a bunch of mathematical functions. Im trying to declare the different fields in the math class and I keep getting error messages!!
This is what I have right now
public class Math
    // Returns the absolute value of a double value.
    double abs(double a);
    // Returns the absolute value of a int value.
    int abs(int a);
    //Returns the greater of two double values.
    double max(double a, double b);
    //Returns the greater of two int values.
    int max(int a, int b);
    // Returns the lesser of two double values.
    double min(double a, double b);
    // Returns the lesser of two double values.
    int min( int a, int b);
    // Returns the value of the first argument raised to the power of
    // the second argument.
    double pow(double a, double b);
    // Returns the remainder of division of two integers.
    int remainder(int a, int b);
    // Returns the closest long to the argument.
    long round(double a);
    // Returns the sum of all the elements in an array of doubles.
    double sum(double [] doubleArr);
    // Returns the sum of all the elements in an array of ints.
    int sum(int [] intArr);
    // Storage for the list of integers used for the int sum method.
    private int [] intArray = {5, 10, 15, 20};
    // Storage for the list of doubles to be used double sum method.
    private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};
    }When I try and compile it tells me that Im missing method body or declare abstract.
I originally had this
   // Returns the absolute value of a double value.
    double abs;
    // Returns the absolute value of a int value.
    int abs;
    //Returns the greater of two double values.

    double pow;
    // Returns the remainder of division of two integers.
    int remainder;
    // Returns the closest long to the argument.
    long round;
    // Returns the sum of all the elements in an array of doubles.

    private int [] intArray = {5, 10, 15, 20};
    // Storage for the list of doubles to be used double sum method.
    private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};When i tried doing this it told me that I had already declared the field previously when it got the the field with the same name and thats why I added the bit in brackets.....
Im so lost... can anybody hep????

Java.lang.RuntimeException: Uncompilable source code - missing method body

Hi,
I am getting the following error at runtime
java.lang.RuntimeException: Uncompilable source code - missing method body, or declare abstractwhen I try to instantiate a class using reflexion as following:
MyInstance = MyClass.newInstance(); I have tried to find some explanation using Google, but could not find any that fit my case. MyClass's implementation has a public constructor with no parameter. There is no error at compile time when cleaning and building all code.
Anyone has tips about what could cause this error?
Thanks.

Missing method body

class Board
    public static void main(String[] args)
        Board example = new Board();
    private Board();
        char array[][];
        array = new char[3][3];
        for (int i = 0; i < 3; i++)
            for (int j = 0; j < 3; j++)
                array[i][j] = '.';
                System.out.println(array[i][j]);
}compiler says missing method body, but i can't think where the error is? private Board has to be a constructor.

Are you using a text editor or an IDE? If you are already fairly familiar with the Java programming language and the java/javac and you understand how classpath works, then you might consider to step over from the text editor to an IDE, such as Eclipse. It will save time and effort in developing. I tried to reproduce your problem in Eclipse and it clearly understrikes the "Board();" part during typing and says "This method requires a body instead of a semicolon" which makes much more sense.

Missing method body and cannot resolve symbol

I keep getting these two errors when trying to compile. I know that I need to call my fibonacci and factorial functions from the main function. Is this why I am getting the missing method body error? How do I correct this?
Am I getting the cannot resolve symbol because I have to set the num and fact to equal something?
Thanks
public class Firstassignment
public static void main(String[]args)
     System.out.println();
public static void fibonacci(String[]args);
     int even=1;
     int odd=1;
     while (odd<=100);
     System.out.println(even);
     int temp = even;
     even = odd;
     odd = odd + temp;
public static void factorial (String[]args);
     for (int count=1;
     count<=num;
     count++);
     fact = fact * count;
     outputbox.printLine("Factorial of" + num + "is" + fact);

Hey... :o)
the problem is that you've put semicolons at the end of the function signature, like this:
public static void fibonacci(String[]args);
}that should happen only when the function is abstract... so ur function should actually look like this:
public static void fibonacci(String[]args)
}also, i think you've missed out on the declarations (like what are fact and num??)....

Compiling Error Method body missing

Error during transport: Method is not declared + Component missing

HI
I got 2 errors when I transport:
Error 1:

1)
When I go to Class Builder (SE24), and make a syntax check for ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT, I got the error:
Class ZCL_ZGW_VH_ORDER_DETAI_DPC_EXT,Protected section

The code looks like this
protected section.

2)
If I go to include ZCL_ZGW_VH_ORDER_DE_01_DPC====CM006 (in SE38), I am navigated to method: DETSET_GET_ENTITYSET (That was the missing method in error 1). When I do a syntax check, I got the error message:

Then I double click at ls_gw_et_details-zz_matr_lev_dato, and got the data statement: DATA ls_gw_et_details LIKE LINE OF et_entityset.
When I double click at et_entityset, I see that the et_enityset is type ZCL_ZGW_VH_ORDER_DE_01_MPC=>TT_ORDDET. Now I double click at TT_ORDDET I got the public section, where I can see that ZZ_MATR_LEV_DATO is already specified.
     ZZ_SPORSP_DATO type D,
     ZZ_KSTROM type STRING,
     ZZ_KSTROM_DATO type D,
     ZZ_MATR_LEV_DATO type D,
end of TS_ORDDET. .
types:
TT_ORDDET type standard table of TS_ORDDET. .
Anyone who will help me?
Thanks

Hi Ron Sargeant,
I'm having a kind of similar issue. I have 3 entities, they were already mapped to theirs respective RFC. In the RFC, a couple of fields changed their name so the mapping got lost. I did again the mapping and there was no errors on 2 of the 3 entities. For other reasons, I had to delete the third entitiy, I deleted it and created it again and there was no problems, I do the mapping and everything was apparently fine, when I tried to "Generate Runtime Objects" it throws me an error with the next message: "Failed to create data provider class". If I try to Generate the service again, it throws me another error message: "The class ZCL_xxx_xx_xxxxxx_DPC is locked. Process canceled". I'm sure I've not edited or deleted the DPC class. If I try to access the DPC class from the tx SE24 it tells me that the object it's not created, and the class still appears in the list of Runtime Artifacts in tx SEGW.
I'd like to know if you've got any idea of what may happen, or I'd also like to be sure that if I delete the DPC class and the DPC_EXT class, it will be regenerated again by the Service Builder.
Best regards,
Ana Velásquez

Problems with loading native library/missing methods:no ttJdbcCS in java.li

Iam facing one problem while connecting the timesten client to the server The SQL Exception which Iam getting is pasted below:-
Problems with loading native library/missing methods: no ttJdbcCS in java.library.path
I am working with MAC OS X 10.7.2 and my timesten client version is 11.2.1.0
I have also changed the Java Preferences from 64-bit to 32-bit but still whenever i tried to connect with the SQL Developer it gives me the above error.

I just tried this out. My environment is OS X 10.7.4, Timesten (32-bit) client 11.2.1.9.0, SQL Developer 3.1.07, Oracle Java 1.7.0_04.
The key things you need to be sure to do (in a terminal window) are:
1. Be sure to . in the TimesTen environment script <tt_install_dir>/bin/ttenv.sh to set the full TT environment.
2. Change directory to SQLDeveloper.app/Contents/Resources/sqldeveloper
3. Run 'sh sqldeveloper.sh -J-d32'
and all should be fine.
Note that if you are using Java7 as I am then there is a step 1a. Change the CLASSPATH environment variable to specify ttjdbc6.jar not ttjdbc5.jar. For some reason running the app directly from Finder does not work even if you add -J-d32 into the sqldeveloper launch script. I'm still looking into that.

WTK22 JSR172Demo - missing SOAP body

Hi,
I tried the sample JSR172Demo provided with WTK22, with the server running on localhost. Hence the WSDL port is as below:
location="http://localhost:8080/serverscript2/serverscript"
The service has been verified to be running. The stubs for the client generated using the KToolbar stub generator tool. The build was successful. However when the client is run and the service is invoked the following error is displayed on the Ktoolbar console:
java.rmi.MarshalException: Missing SOAP Body or Envelope
at example.serverscript.connector.Interface_Stub.request(+125)
at example.serverscript.demo.Demo.run(+23)
Please let me know if anyone has faced a similar problem and found a solution.
Thanks,

I have simular problem:
"Missing SOAP Body or Envelope exception" when I'm trying to call web-service methos through internet.
It seems there is something wrong with my computer security settings - can't imagine what's wrong.
With local web-server everything works fine.
I tryed to change Security Domain to Trusted, but this doesn't helps.

Java.lang.NoSuchMethodError: java/util/Vector method revove...

After using jexegen from microsoft to make EXE. I receive this error when i execute the my EXE :
java.lang.NoSuchMethodError: java/util/Vector method revove...
Any body know why?
If i execute from JBuilder i have no problem!

hi, i don't have much experience with M$ java products, but as far as i remember, M$ java stopped developping since jdk 1.1.4 (or 1.1.7).
maybe that's the reason for throwing this exception. if you want to "exe" your class-file, try JToExe.

Why java allow start() method only once for a thread

Hi ,
Why java allows start method only once for thread . suppose
Thread t = new Thread();
t.start();
say at later stage if again we call t.start() IllegalStateException is thrown , even though isAlive method returns false.
Hence the question , why start() method is allowed only once.If you need start a thread , we need to create a new instance.

Really. Why do you think that? Do you have any evidence? It is one of the first things I would think of, personally.Considering that the Thread API doesn't allow you to specify a stack address (only stack size), I think it demonstrates they wanted to remove that capability from their Thread API all together. That missing "capability" makes me believe they want me to believe it's not something I need to worry about when using their API... I think the exact semantics of the Thread class and its methods were driven by how to make it most understandable and usable for their customers. I'm certain this issue was one of many that was given considerable thought during the design and implementation of the JVM and the underlying runtime classes.
Do I have any evidence? No. But if you can point me at some first-hand information on this, I'd love to read it. Most of what I've found is second or third hand accounts. (and I mean that sincerely, not as a smart-ass remark or rebuke of your comments).
On the one hand you seem to think the Java API designers are idiots, on the other hand you think that they should be. I can't make it out.I thought my position was that the Java developers were talented enough to implement platform in whatever way their API called for; hence, the designers made a choice about how they wanted their API to be used by their customers. They decided which capabilities they wanted to include or exclude, and created an API that was consistent with their vision for this technology. While I'm certain technical limitations had an effect on the API design, I certainly don't think the API was dictated by the them.
I think the current design of the Java Thread API was a reflection of their vision to make Threading easier and more accessible to Joe Programmer, not limitations in the implementation. I never said it was wrong or that I could do better... I just said I think they could have done something different if they decided it would have made for a better customer experience. But hey, maybe I'm wrong.

Java interface as method arg question.

Hello,
Imagine that I have the following two interfaces and their associated classes:
AI, AC, FooI, FooC
where AC and FooC implements the interfaces AI and AC respectively. Assume than that FooI has contains only the following method:
public void doIt(AI arg);
So far so good. Now assume that FooC attempts to implement the method in it's interface like so:
public void doIt(AC arg);
The java compiler complains thusly:
C:\moment\javatest>javac AC.java AI.java FooC.java FooI.java
FooC.java:1: FooC should be declared abstract; it does not define doIt(AI) in FooC
public class FooC implements FooI
I was surprised by this result. Since AC honors AIs contract, why is the compiler complaining. If someone could explain the reasoning behind the error, I'd really appreciate it. Thanks in advance.
-exits

AC may be an implementation of AI, but not every implementation of AI is AC.
The FooI interface is essentially insisting that the method work on every implemenation of AI. If you create a method that works only on a particular subset of AIs, namely ACs, then you haven't really implemented the method as specified.
