如何从 Java swing 中的 txt 文件中将特定数据放入组合框中

Question

I am currently working on an assignment that requires me to show the item inside the menu.txt to the user inside the combobox. And the data stored inside the menu.txt is like

1    Pizza     $50
2    CocaCola  $3
3    Rice      $1

The currently code that im using is:

    public void fillComboFromTxtFile(){
    File file = new File("Menu.txt");
    try{
        BufferedReader br = new BufferedReader(new FileReader(file));
        Object[] lines = br.lines().toArray();
        
        for (int i=0;i<lines.length;i++){
            String line = lines[i].toString();
            cbName.addItem(line);
        }
        
    }catch(FileNotFoundException ex){
        Logger.getLogger(Order.class.getName()).log(Level.SEVERE,null,ex);
    }
    
}
        

But instead of showing the name of the food, the item listed inside the combo box is like

1Pizza$50
2CocaCola$3
3Rice$1

What I really want in my combo box is like only showing

Pizza
CocaCola
Rice

What am I suppose to do? Thanks

You have also to split the line at the whitespaces and take the first element, because that is the name

    public void fillComboFromTxtFile(){
    File file = new File("Menu.txt");
    try{
        BufferedReader br = new BufferedReader(new FileReader(file));
        Object[] lines = br.lines().toArray();
        
        for (int i=0;i<lines.length;i++){
            String line = lines[i].toString();
            cbName.addItem(line.split("\\s+")[1]);
        }
        
    }catch(FileNotFoundException ex){
        Logger.getLogger(Order.class.getName()).log(Level.SEVERE,null,ex);
    }
    
}
