阵列到阵列的阵列面临问题。我的程序将表格数据保存为单独的文本文件(每天单独的文件)。现在我想阅读所有内容并对每个字段进行求和。 我保存的文本文件看起来像:阵列阵列到表
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
我已经manged方法来读取并保存数值到数组[] []。但现在我需要将这些数组打印到表格中。
这是我从文件中读取代码:
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);
}
});
这里是我得到的问题代码:
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][]);
}
});
错误代码: INT不能转换为矢量
但我应该将其转换为矢量?可能有另一种方法在表格中显示它?
没有第二个括号它是相同的错误代码。 – Vilhis
有一些代码缺失,但我猜'tableModel'类型'AbstractTableModel',而不是'DefaultTableModel' – Paul
所以我想要做的就是以某种方式显示我的数组[] []到表。是否有必要将所有我的'int数组'按字段转换为向量或目标表字段,还是有另一种方式来显示它? – Vilhis
