Java 如何从表模型中获取所选行？

如何从表模型中获取所选行？ 我试过以下方法

checkBoxes[t].addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent  e) {

    int index = -1;
    for (int i = 0; i < checkBoxes.length; i++) {
      if (checkBoxes[i] == e.getSource()) {

        String Status=null ;
        DbUtility ViewAbsenties=new DbUtility();
        ViewAbsenties.loadDriver();
        ViewAbsenties.connect();

        TableModel tm;
        tm = table3.getModel();

        if (checkBoxes[i].isSelected() == true) {
          Status  =(String) tm.getValueAt(i,8);
          System.out.println("Status : " + Status );

        }
      }
    }
  }
}

有三个潜在问题

• 我们的观点可能是，你必须这样做

• 以零开始的数组（

  getValue（0，0

  ）是

  1st.row

  中的

  1st.column

  ）

• 必须正确设置或确定所有选定行

为了得到更好的帮助，请尽快发布

请对代码块使用一致的逻辑缩进。错误表明您尝试访问的行不存在。您的表是否至少有9列？您是否尝试记录您认为对象位于哪一行，并根据您对模型的解释验证这一点？此问题与其他问题有关（选择是复选框，而不是表格选择，并查找值而不是索引）但是一些查看标题的人可能希望找到这样一个结果：请对代码块使用一致的逻辑缩进。您的错误表明您尝试访问的行不存在。您的表是否至少有9列？您是否尝试记录您认为对象位于哪一行，并对照您对模型的解释进行验证？这个问题是关于一些不同的内容（选择是复选框，而不是表格选择，并寻找值而不是索引），但一些查看标题的人可能希望找到以下内容：
