陣列到陣列的陣列面臨問題。我的程序將表格數據保存爲單獨的文本文件(每天單獨的文件)。現在我想閱讀所有內容並對每個字段進行求和。 我保存的文本文件看起來像:陣列陣列到表
0 Name auto note note.tot insurance ins.tot offer
1 john 51 6 2 21 44 12
2 peter 32 5 1 36 65 20
3 smith 12 2 1 45 53 9
4 mike 5 0 0 17 55 11
我已經manged方法來讀取並保存數值到數組[] []。但現在我需要將這些數組打印到表格中。
這是我從文件中讀取代碼:
OK4.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
File f = new File(fileName);
if (f.exists()) {
try {
tableModel = new DefaultTableModel(new Object[] {"#", "Name", "auto", "note", "note.tot", "insurance", "ins.tot", "offer"},0);
BufferedReader br = new BufferedReader(new FileReader(fileName));
String line = br.readLine();
String[] colHeaders = line.split("\\s+");
tableModel.setColumnIdentifiers(colHeaders);
while ((line = br.readLine()) != null) {
String[] data = line.split("\\s+");
tableModel.addRow(data);
}
} catch (Exception ex) {
ex.printStackTrace();
}
} else {
JOptionPane.showMessageDialog(null, "This date was not saved");
};
table.setModel(tableModel);
table.getColumnModel().getColumn(0).setMaxWidth(22);
}
});
這裏是我得到的問題代碼:
OK5.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
int[][] array = null;
int counter = 0;
mon = (String) month.getValue();
for (int i = 1; i < 32; i++) {
counter = 0;
fileName= mon + i + ".txt";
File f = new File(fileName);
if (f.exists()) {
try {
BufferedReader br = new BufferedReader(new FileReader(fileName));
String line = br.readLine();
String[] colHeaders = line.split("\\s+");
tableModel = new DefaultTableModel(new Object[] {"#", "name", "auto", "note", "note.tot", "insurance", "ins.tot", "offer"}, 0);
tableModel.setColumnIdentifiers(colHeaders);
while ((line = br.readLine()) != null) {
counter = counter + 1;
String[] info = line.split("\\s+");
for(int j = 2; j < 8; j++) {
int num = Integer.parseInt(info[j]);
array[j][counter]=array[j][counter] + num;
}
};
} catch (Exception ex) {}
};
};
// and here is trying to display it. but it wont work
tableModel.addRow(array[1][]);
}
});
錯誤代碼: INT不能轉換爲矢量
但我應該將其轉換爲矢量?可能有另一種方法在表格中顯示它?
沒有第二個括號它是相同的錯誤代碼。 – Vilhis
有一些代碼缺失,但我猜'tableModel'類型'AbstractTableModel',而不是'DefaultTableModel' – Paul
所以我想要做的就是以某種方式顯示我的數組[] []到表。是否有必要將所有我的'int數組'按字段轉換爲向量或目標表字段,還是有另一種方式來顯示它? – Vilhis
