Question

当我尝试使用向量填充Psr/Log时，我收到以下错误。

错误：

JTable

这是我的代码：

我的代码有什么问题？

Answer 1

从异常中，您必须将String对象添加到fileVector，如下所示：

Vector fileVector = new Vector();
fileVector.add("a string object");

这是违反DefaultTableModel的实现，要使用它需要将Vector对象添加到fileVector中，如下所示：

Vector fileVector = new Vector();
fileVector.add(new Vector(Arrays.asList(new String[]{"row1 col1", "row1 col2"})));
fileVector.add(new Vector(Arrays.asList(new String[]{"row2 col1", "row2 col2"})));

干杯

使用Vector填充JTable？
