New to the forum + assistance :)

[quemadissimo]

Hey everyone I'm new to the forum and I signed up because I'm new in Java programming and I am really stuck and I would like more advanced people to assist me.
Thank you in advance :)

The problem is the following: I try to compile, and even though NetBeans doesn't detect any error prior to running, when I do run it I get the following error:

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - reached end of file while parsing
at obligatorio.Prueba.main(Prueba.java:19)
Java Result: 1

Here's the code:

package obligatorio;
import java.util.Scanner;
public class Prueba {
    public static void main(String[] args) {
         Scanner input = new Scanner(System.in);
    Empresa E1;
    E1 = new Empresa();
    Empleado P1;
    P1 = new Empleado();
                System.out.println("1: Registre una empresa");
        System.out.println("2: Registre un empleado");
        System.out.println("3: Registre cosa larga");
        int opcion = 0;
          
do {   System.out.println("Seleccione una opcion: ");
            opcion = input.nextInt();
            boolean entrada = false;

        switch(opcion){
            case 1:{
                opcion = 1;
                System.out.println("Ingrese nombre: ");
                E1.setNombre(input.next());
                System.out.println("Ingrese rut: ");
                E1.setRut(input.next());
                break;}
            case 2:{
                opcion = 2;
                System.out.println("Ingrese nombre: ");
                P1.setNombre(input.next());
                System.out.println("Ingrese direccion: ");
                P1.setDireccion(input.next());
                System.out.println("Ingrese documente: ");
                P1.setDocumento(input.next());
                break;}
            case 3:{
                opcion = 3;
                System.out.println("Aca va la cosa larga");
                break;}
        }
                if(opcion == 1, 2, 3)){
entrada = true
        {
            while (entrada = true){
            }
        

}

Can you guys tell what's wrong with the programming? It's most likely a beginner's mistake! Thanks again!

Your braces have to "match". What I mean is that for each { there has to be a later }. I think you may be missing a }.

Note that you don't need to put braces around the blocks of code that make up each of the cases. You can just say:

switch(opcion) {
    case 1:
        opcion = 1;
        System.out.println("Ingrese nombre: ");
        E1.setNombre(input.next());
        System.out.println("Ingrese rut: ");
        E1.setRut(input.next());
        break;
    case 2:
        opcion = 2;
        // etc

Also the line "opcion = 1;" is not really needed because you wouldn't get there unless the user had entered 1 and opcion would already be 1.

if(opcion == 1, 2, 3)) {

This doesn't make sense. Perhaps you should read up about conditional operators to see how you can express the condition "opcion is 1 or opcion is 2 or opcion is 3".

Finally use lower case letters to start variables. And make the variables readable even if that makes them a little longer.

//Empresa E1;
//E1 = new Empresa();
Empresa empresa = new Empresa();

I haven't addressed the "while(entrada=true){}" business because these other things should be corrected first.

And then you can say what this while loop was supposed to do.

okay thank you, I seem to have fixed the problem and it runs correctly now.
The code is now as follows:

import java.util.Scanner;
public class Prueba {
    public static void main(String[] args) {
         Scanner input = new Scanner(System.in);
    Empresa e1;
    e1 = new Empresa();
    Empleado p1;
    p1 = new Empleado();
                System.out.println("1: Registre una empresa");
        System.out.println("2: Registre un empleado");
        System.out.println("3: Registre cosa larga");
        int opcion = 0;
        boolean entrada = false;

        while(entrada = true){
    System.out.println("Seleccione una opcion: ");
    opcion = input.nextInt();
    

    
    switch(opcion){
       case 1:
                       System.out.printf("Ingrese nombre: ");
                e1.setNombre(input.next());
                System.out.printf("Ingrese rut: ");
                e1.setRut(input.next());
                entrada = true;
                System.out.println(e1);
                break;
            case 2:
                opcion = 2;
                System.out.printf("Ingrese nombre: ");
                p1.setNombre(input.next());
                System.out.printf("Ingrese direccion: ");
                p1.setDireccion(input.next());
                System.out.printf("Ingrese documento: ");
                p1.setDocumento(input.next());
                entrada = true;
                System.out.println(p1);
                break;
            case 3:
                opcion = 3;
                System.out.printf("Aca va la cosa larga");
                entrada = true;
                break;
        }
        }
    }
}

The only problem I seem to be having now is with the input.next(); as it takes only the first word typed as the value when the value should be more than one word in direccion (spanish for address), for instance, which should have a number and a street name. The code as it is now uses the first word as the value for the first set* and the second one for the following one. How do I make input.next() use everything the user types until they hit enter as the value for the first setting?

next reads the next token. If your delimiter is space (the default) then you only get one word read at a time. Use nextLine to read the whole line.
