不能得到數組表標題正確

Question

我有下面的代碼位：

的問題是不能似乎得到了標題到一個單獨的表中的列，而我的列標題，如在本部分中定義

String[] columnNames ={container.toString()}; 

並從

URLConnection yc = oracle.openConnection(); 
BufferedReader in = new BufferedReader(new InputStreamReader(
yc.getInputStream())); 
//create array-------------- 
ArrayList list = new ArrayList(); 


Scanner scanner = new Scanner(in); 
while (scanner.hasNextLine()) { 
String line = scanner.nextLine(); 
//add line to array------------- 
list.add(line); 
} 
//get headings of data------------------ 

//String heading[] = list.get(2).toString(); 
String[] simpleArray = new String[list.size()]; 

list.toArray(simpleArray); 

String j = (String) list.get(2); 

String [] items = j.split(";"); 
List<String> container = Arrays.asList(items); 



createUserInterface(container); 

衍生出現在其整體中的第一列（並且因此在表中唯一的列） 我因此ö NLY看 「名」 出現在數據字段

的println我的標題是

[A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R,S] *I have substituted my actual headings with letters 

幫助表示讚賞

代碼below--

public void createUserInterface(List<String>container) { 
//create user interface---------------------  
setLayout(new BorderLayout()); 
setTitle("Fund");//setTitle is also a JAVA Parameter 
setSize(2000, 200); 
setBackground(Color.gray); 
setDefaultCloseOperation(EXIT_ON_CLOSE); 
// Create a panel to hold all other components 
JPanel topPanel = new JPanel(); 
topPanel.setLayout(new BorderLayout()); 
getContentPane().add(topPanel); 
// 


System.out.println(container.toString()); 

List list = Arrays.asList(container); 

Object[] columnNames ={list}; 
Object[][] data = {{"First Name", "Last Name", "Sport", "# of Years","First Name", "Last Name", "Sport", "# of Years","First Name", "Last Name", "Sport", "# of Years","First Name", "Last Name", "Sport", "# of Years","First Name", "Last Name", "Sport", "# of Years"}}; 



table = new JTable(data, columnNames); 
// Create a new table instance 
scrollPane = new JScrollPane(table); 
topPanel.add(scrollPane, BorderLayout.CENTER); 

setVisible(true); 



}

你有什麼期望，這將返回：container.toString()？這怎麼可能代表你的表格標題？

如果你想從A到S的字母是你的JTable列標題（這就是你想要做的猜想），爲什麼不簡單地使用這個數組呢？

String[] columnNames = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", 
     "K", "L", "M", "N", "O", "P", "Q", "R", "S"}
