如何將此代碼轉換爲類並重用它？

我已經寫了這個枚舉來配置我的程序參數...
那麼我想翻譯爲一個類。如果是SingletonClass，則更好。我的大問題是，我不知道如何在運行時的參數值設置...如何將此代碼轉換爲類並重用它？

package GUI;

如果你重構它，它會產生幾個類，每個類表示一個const來自enum的螞蟻。你確定要這麼做嗎？ –

我不想有幾個類，我相信它會是資源昂貴... – Tilens

我只是想嘗試重寫它有一個類或其他類型，我可以使用（更改參數字段...）我的下一個配置步驟有...傳感器屬性，例如... – Tilens

讀了一些關於後和Singleton in Java使用Netbeans各種測試之後...... 我創造了這個圖書館是爲我工作好，似乎不是很沉重......

package com.tilens; 

public class Configurador{ 
    private static Configurador INSTANCIA; 
    private final static Object sync=new Object(); 
    private static List<Campo>campos; 
    private Configurador(){ 
    campos=new ArrayList<>(); 
    System.out.println(Thread.currentThread().getName()+"> Creando Instancia..."); 
    } 
    public static Configurador getInstance(){ 
    synchronized(sync){ 
     if(INSTANCIA==null)INSTANCIA=new Configurador(); 
     else System.out.println(Thread.currentThread().getName()+"> Obteniendo Instancia..."); 
    } 
    return INSTANCIA; 
    } 
    public void addCampo(String caption,String value){ 
    Campo tmp=new Campo(caption,value); 
    campos.add(tmp); 
    } 
    public synchronized int show(JFrame padre){ 
    JPanel pnlContenedor,pnlControles; 
    GridBagConstraints constraints; 

    pnlControles=new JPanel(new GridBagLayout()); 
    pnlControles.setBorder(BorderFactory.createTitledBorder("Campos:")); 

    constraints=new GridBagConstraints(); 
    constraints.gridwidth=1; 
    constraints.gridheight=1; 
    constraints.ipadx=4; 
    constraints.ipady=4; 

    for(int i=0;i<campos.size();i++){ 
     Campo cmp=campos.get(i); 
     constraints.gridx=0; 
     constraints.gridy=i; 
     constraints.anchor=GridBagConstraints.LINE_END; 
     pnlControles.add(cmp.getLabel(),constraints); 
     constraints.gridx=1; 
     constraints.anchor=GridBagConstraints.LINE_START; 
     pnlControles.add(cmp.getField(),constraints); 
     //if(cmpFocus==null) cmpFocus=campo.field; 
    } 

    pnlContenedor=new JPanel(new BorderLayout()); 
    pnlContenedor.setMaximumSize(new Dimension(500,500)); 
    //pnlContenedor.add(new JScrollPane(pnlControles)); 
    pnlContenedor.add((pnlControles)); 
    return JOptionPane.showConfirmDialog(padre,pnlContenedor,"titulo",JOptionPane.OK_CANCEL_OPTION); 
    } 
} 
class Campo{ 
    private final String label; 
    private final Component field; 
    public Campo(String caption,String value){ 
    field=new JTextField(value); 
    label=caption; 
    } 
    public String getCaption(){ 
    return label+": "; 
    } 
    public JLabel getLabel(){ 
    return new JLabel(getCaption()); 
    } 
    public String getFieldClass(){ 
    return field.getClass().getSimpleName(); 
    } 
    public Component getField(){ 
    return field; 
    } 
}

我希望能爲別人有用，幫助我準確的代碼...
