使用rowindex从JTable检索行数据
如何使用rowindex从JTable检索行数据？
我认为这可以在比@ user489041的答案少几行的情况下完成。 😉
试试这个示例代码：
int selectedRowIndex = jTable.getSelectedRow(); int selectedColumnIndex = jTable.getSelectedColumn(); Object selectedObject = (Object) jTable.getModel().getValueAt(selectedRowIndex, selectedColumnIndex);
将“对象”替换为表中存储的任何内容，例如“String”。
如果已设置JTable以便用户只能选择整行，则将“selectedColumnIndex”替换为要从中检索内容的列的索引。
在Swing中，每个UI组件都有一个“管理”数据的相应模型。 大多数情况下，您可以通过在组件上调用getModel()来获取模型。 对于JTable ，模型是TableModel类。 在那里，您可以使用方法getRowCount() ， getValueAt(x,y)和getColumnCount()来访问表的数据。
