英文:
Get all checked value from the table
问题
这是我需要的输出：
这是我目前编写的代码：
TableModel model = table_test.getModel();
for (int i = 0; i < model.getRowCount(); ++i) {
Boolean isChecked = Boolean.valueOf(model.getValueAt(i, 0).toString());
String col = model.getValueAt(i, 1).toString();
if (isChecked == true) {
try {
textarea.setText(col);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
}
}
这段代码只会在文本区域显示一个值。
希望你能帮我解决这个问题。

你可以尝试以下代码：
TableModel model = table_test.getModel();
for (int i = 0; i < model.getRowCount(); ++i) {
Boolean isChecked = Boolean.valueOf(model.getValueAt(i, 0).toString());
String col = model.getValueAt(i, 1).toString();
if (isChecked == true) {
try {
textarea.append(col);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
}
}
英文:
You can try below.
TableModel model = table_test.getModel();
for(int i=0; i<model.getRowCount();++i)
{
Boolean isChecked = Boolean.valueOf(model.getValueAt(i, 0).toString());
String col = model.getValueAt(i,1).toString();
if (isChecked==true) {
try{
textarea.append(col);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e);
}
}
}
