I have a game implemented in java, to roll a dice and pass the points and if it rolls 1 the points remain at zero and if the turn passes the points are saved and whoever reaches 100 wins currently I only have two frames but I What happens is that I don't add the client and server classes to the code already done, but I don't know how to make the game methods that are in the frame handle them to the server. Can someone help me?

Hello, I have taken some fragments of a code, and I do not understand these fragments, could you explain to me what function they fulfill? Thank you...

1-

} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

two-

public String toString() {
    return (getNombre() + " " + getP_Apellido() + " "
            + getS_Apellido());

}

3-

public static void main(String[] args) {
    Employee e = new Employee();
    e.name = "Reyan Ali";
    e.address = "Phokka Kuan, Ambehta Peer";
    e.SSN = 11122333;
    e.number = 101;

    try {
        FileOutputStream fileOut
                = new FileOutputStream("employee.ser");
        ObjectOutputStream out = new ObjectOutputStream(fileOut);
        out.writeObject(e);
        out.close();
        fileOut.close();
        System.out.printf("Serialized data is saved in /employee.ser");
    } catch (IOException i) {
        i.printStackTrace();
    }
}

4-

public void mailCheck() {
    System.out.println("Mailing a check to " + name
            + " " + address);
}

5-

Employee e = null;
    try {
        FileInputStream fileIn = new FileInputStream("employee.ser");
        ObjectInputStream in = new ObjectInputStream(fileIn);
        e = (Employee) in.readObject();
        in.close();
        fileIn.close();
    } catch (IOException i) {
        i.printStackTrace();
        return;
    } catch (ClassNotFoundException c) {
        System.out.println("Employee class not found");
        c.printStackTrace();
        return;
    }
    System.out.println("Deserialized Employee...");
    System.out.println("Name: " + e.name);
    System.out.println("Address: " + e.address);
    System.out.println("SSN: " + e.SSN);
    System.out.println("Number: " + e.number);
}

I would be grateful if you could explain to me what each code does, they are fragments of a complete code that I do not understand, thank you very much in advance...

I have the Client program:

class Cliente {
static final String HOST = "localhost";
static final int PUERTO=5000;
public Cliente( ) {
try{
Socket skCliente = new Socket( HOST , Puerto );
InputStream aux = skCliente.getInputStream();/* A partir de aquí no entiendo lo que hace */
DataInputStream flujo = new DataInputStream( aux );
System.out.println( flujo.readUTF() );
skCliente.close();  ... /* Hasta aquí */
} catch( Exception e ) {
System.out.println( e.getMessage() );

}
}
public static void main( String[] arg ) {
new Cliente();
}
}

And I have the Server program:

class Servidor {
static final int PUERTO=5000;
public Servidor( ) {
try {
ServerSocket skServidor = new ServerSocket(PUERTO); /* A partir de aquí no entiendo lo que hace */
System.out.println("Escucho el puerto " + PUERTO );
for ( int numCli = 0; numCli < 3; numCli++; ) {
Socket skCliente = skServidor.accept(); // Crea objeto
System.out.println("Sirvo al cliente " + numCli);
OutputStream aux = skCliente.getOutputStream();
DataOutputStream flujo= new DataOutputStream( aux );
flujo.writeUTF( "Hola cliente " + numCli );
skCliente.close();... /* Hasta aquí */
}
System.out.println("Demasiados clientes por hoy");
} catch( Exception e ) {
System.out.println( e.getMessage() );
}
}
public static void main( String[] arg ) {
new Servidor();/* No entiendo para que esta este main aqui? */
}
}

Could you explain to me line by line what each program does?, to better understand the issue of sockets.

In Bogotá there is a main office where the main and backup servers are located. For the interconnection of the offices, it is desired to contract fiber optics, seeking that all the offices have fast and reliable access to the servers of the main office. Locally at each venue, it is planned to have a high-speed connection for each computer equipment. The Cities where there is coverage are determined below: BOGOTÁ: Number of Venues: 3 Number of teams: 420 Description: These are venues located in distant districts for better coverage and each venue has buildings with an area of ​​over 2000 m2, with structured cabling. At Headquarters there are 210 teams, at venue B there are 90 and at venue C 120 teams. MEDELLÍN: Number of Venues: 2 Number of Teams: 250 Description: Two small identical venues with an area of ​​1200 m2, each with 125 teams. MANIZALES: Number of Venues: 1 Number of Teams: 50 PEREIRA: Number of Venues: 1 Number of Teams: 120

From the above, I implemented it in cisco packet tracert, I was thinking of implementing it as shown in the image, but I don't know if the connection between the 4 cities is correct as stated in the statement. , but I don't know if it will be possible or what else do I have to add? so that it is well implemented based on the description?

I developed a game in Java and I have to do unit tests on it. I do them and I get an error in the tests but I don't understand why, if the game works as expected. The test code is as follows:

    public static void tearDownClass() {
    }

    public void setUp() {
    }

    @After

    }

    /**

    @Test
    public void testMensaje() {
        System.out.println("Mensaje");
        Constelacion instance = new Constelacion();
        instance.Mensaje();
        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }

    /**

    public void testCleanBoton() {

    public void testMain() {

        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }

}

And when I run it I get this error in the tests. Could someone tell me why the result is wrong?

I have a problem when executing my program, I get a little hammer where the classes are and it won't let me execute it. I get that hammer:

The strange thing is that all the classes are there and the frames but it does not let them execute, can someone help me?

I have a problem I am developing a game to find objects in java. What happens is that the buttons (in this case 5) will be blank after the player finishes finding all the objects.

What I want is that when those 5 objects reach white, a message appears that you won, but I don't understand how to call those 5 buttons, so that when the 5 are already blank, the message appears, can someone help me? Thank you

I am making a game in java, but when I run the Frames I get a small window and I hit maximize and it maximizes me, but the idea is that it comes out at once of the size it is, I edit the Frame properties and I maximize the size and it doesn't give me, is there any other way?

I use the Frames with Layout null to put the images and from there it gives the error... Thanks if someone knows how to maximize the frame I would appreciate it very much

I am making a game of hidden objects in java, where I have an interface with many labels(30 or more) that have an image, and the interface also has 5 buttons which have the names of 5 images of the interface, and with those names search for the image and click on it and it will disappear, and after that the button changes its name to another image after an object is found, to be more exact it is like something similar to the famous game Criminal Case, my problem is that I implemented all the code as shown below, I don't get any errors but they don't do the functions they should do well, in the code the methods appear underlined in yellow, I don't know if that's it... Could someone help me?

Can you help me with this? I declared those two methods that I mentioned in the title and I get an error in the if and I don't understand why.

I would like to know why this code does not send me data from one Jframe to another. I have two fields (textField), one (num1) in a Jframe called purchases and the other (p4) in another Jframe called invoice.

What I want is that I type any word in the shopping field called num1 and it appears in the other field (p4) of the other JFrame.

For that I execute the following code, in a button called invoice, as shown below. But it does not send the word.

What could be the problem?

private void BotonFacturaActionPerformed(java.awt.event.ActionEvent evt){             
    String dato; //variable que gusrda la informacion que se dijite el JTextField llamado num1
    dato=num1.getText();//estoy capturando lo que se digite en el campo num1 y guardandolo en la variable dato
    new Factura().setVisible(true);//la ventana que recibe los datos se abra
    Factura.p4.setText(dato);//envia el dato a la variable de la factura
}    

I have a doubt. I have executed this program in which in netbeans it makes a statement that if the money is less than the total, it will come out cantidad no suficienteand, if it is entered again, and this time it is enough, then the invoice will come out.

I know how to execute it by java, but I don't know how this same procedure would be done in a JFramewindows.

For example, if I said a price in a TextField, this would be money as stated in the if, and the total would be another TextFieldwith another amount.

if (dinero< total){
            System.out.println("el dinero es INSUFICIENTE.");
            System.out.println("\n si desea cambiar la cantidad de dinero digite CORREGIR, sino no lo desea digite CANCELAR");
            respuesta= leer.next();
             if(respuesta.equalsIgnoreCase("corregir")){
                 option= true;
             }else{
                 if(respuesta.equalsIgnoreCase("cancelar")){
                     System.out.println("pedido cancelado.");
                     option=false;
                 }else{
                 System.out.println("el pedido fue cancelado.");
                 }
             }
        }
        }while(money<total && option!= false);

//--devuelta--//
        double devuelta; 

        if (money>= total){
            devuelta= total-money;
            System.out.println("Restaurante el Mirador:");
            System.out.println("FACTURA:");

I would like to know what statement can be made so that I do not get an error if I leave blank spaces.

For example I have 11 textFieldin a JFramein netbeans. If I fill those 11, it makes me the normal sum, but if for example of those 11 I only want to fill 5 or 2 or 3 or 7 or 4 or 1, etc; It throws me an error if I leave those blank, and it no longer does the sum.

How can I fix the problem? I know that with a IgnoreCaseI can make it not leave blank spaces when I fill out a form, but I don't know how to make it leave blank spaces and continue executing the ordinary sum.

In other words, count it as if it were a 0 but without putting a zero in the sum.

How do I loop through a list? How do I go through the data of it as such to a Jframe window called shopping ... from a control I load a list in a Jframe but I would like to know how to go through it with what code is it done?

I am working with events in Java Swing and it happens that in a JFrame I have uploads of three images. What I need is to know how I can make it so that when I press an image when the program runs, it moves vertically and I myself can stop it with another click or by clicking on the second image. If I click on the second image, the first one should stop and the other one should start moving. How can I get this result in Netbeans?
