How do I add values in a vector?

0

Well ... I know how to add values into a vector. Actually, that's not quite it. I'm learning Java a short time ago and started working with netbeans. The teacher requested an activity to create a registration form for students.

So far the code looks like this:

A Student class:

public class Aluno {

    private int matricula;
    private String nome;
    private int RG;
    private int CPF;
    private int fone;
    private int celular;
    private String rua;
    private int numero;
    private String bairro;
    private String cidade;

    /**
     * @return the matricula
     */
    public int getMatricula() {
        return matricula;
    }

    /**
     * @param matricula the matricula to set
     */
    public void setMatricula(int matricula) {
        this.matricula = matricula;
    }

    /**
     * @return the nome
     */
    public String getNome() {
        return nome;
    }

    /**
     * @param nome the nome to set
     */
    public void setNome(String nome) {
        this.nome = nome;
    }

    /**
     * @return the RG
     */
    public int getRG() {
        return RG;
    }

    /**
     * @param RG the RG to set
     */
    public void setRG(int RG) {
        this.RG = RG;
    }

    /**
     * @return the CPF
     */
    public int getCPF() {
        return CPF;
    }

    /**
     * @param CPF the CPF to set
     */
    public void setCPF(int CPF) {
        this.CPF = CPF;
    }

    /**
     * @return the fone
     */
    public int getFone() {
        return fone;
    }

    /**
     * @param fone the fone to set
     */
    public void setFone(int fone) {
        this.fone = fone;
    }

    /**
     * @return the celular
     */
    public int getCelular() {
        return celular;
    }

    /**
     * @param celular the celular to set
     */
    public void setCelular(int celular) {
        this.celular = celular;
    }

    /**
     * @return the rua
     */
    public String getRua() {
        return rua;
    }

    /**
     * @param rua the rua to set
     */
    public void setRua(String rua) {
        this.rua = rua;
    }

    /**
     * @return the numero
     */
    public int getNumero() {
        return numero;
    }

    /**
     * @param numero the numero to set
     */
    public void setNumero(int numero) {
        this.numero = numero;
    }

    /**
     * @return the bairro
     */
    public String getBairro() {
        return bairro;
    }

    /**
     * @param bairro the bairro to set
     */
    public void setBairro(String bairro) {
        this.bairro = bairro;
    }

    /**
     * @return the cidade
     */
    public String getCidade() {
        return cidade;
    }

    /**
     * @param cidade the cidade to set
     */
    public void setCidade(String cidade) {
        this.cidade = cidade;
    }

}

And the code in jNewFrame looks like this:

public NewJFrame() {
        initComponents();
        a = new Aluno[40];
    }

    /**
     * This method is called from within the constructor to initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is always
     * regenerated by the Form Editor.
     */

It happens that when you click the save button (jButton7) it should set the values of each textfield to its respective variable (eg: Field Name -> setar for String Name), doing this for all values in the textfield and store this information into a vector (vector a).

I could not do it and I hope you have understood and can help me solve this problem.

Thanks to all.

You can put it like this:

jButton7.addActionListener(new java.awt.event.ActionListener() {
     public void actionPerformed(java.awt.event.ActionEvent evt) {
         Aluno aluno = new Aluno();//cria uma instancia do objeto aluno
         //seta os valoes pegando dos campos do seu formulario
         aluno.setNome(jTextField1.getText());//campo com o nome 
         //....etc vai preenchendo todas as propriedades

         //adiciona o objeto aluno na list
         a.[indiceQueVoceVaiUsar] = aluno;
     }
});

You will only have to control the vector indices.

See if it helps.
