我在过去三天试图解决这个问题。我是Java世界的新手。我的任务是，
有两个表T1和T2。 T1的第一列是复选框。 一旦T1中的复选框将所选行复制到T2。当我取消选中该复选框时，它应自动从T2中删除所选行。 这里只有鼠标释放事件没有按钮动作。
private void setTotalAmounts() {
DefaultTableModel model = (DefaultTableModel) BillRedemptionTable.getModel();
DefaultTableModel model1 = (DefaultTableModel) jTable2.getModel();
int checkeditemno = 0;
int rownum[] = BillRedemptionTable.getSelectedRows();
for (int i = 0; i < rownum.length; i++) {
boolean isChecked;
isChecked = (Boolean) BillRedemptionTable.getValueAt(rownum[i], 1);
if (isChecked) {
try {
checkeditemno++;
//fetch values from first table rows
int billno = Integer.parseInt((String) model.getValueAt(rownum[i], 2));
int billamount = Integer.parseInt((String) model.getValueAt(rownum[i], 4));
String artype = (String) model.getValueAt(rownum[i], 5);
//add the above values to second table row
model1.addRow(new Object[]{billno, billamount, artype});
} catch (NumberFormatException e) {
System.err.println(e.getMessage());
}
} else if (!isChecked) {
//this code is to remove rows from second table where checkboxes unchecked in the first table
for (int j = 0; j < jTable2.getRowCount(); j--) {
model1.removeRow(rownum[i]);
}
}
}
}
这是我目前正在使用的代码。
任何人都可以帮助我......
when unchecking one row (row number 8)
如果取消选中一行，我在Netbeans IDE中收到以下错误
