如何在Object []类变量中添加元素？

Question

如何在Object[]类变量中添加元素？我有arrayList个包含DTO类数据的对象（第125行，第6列）。我想在JTable中显示所有数据。

String[] columnNames = {"TEST CASE NUMBER", "NO OF EXECUTION", "TOTAL NO OF PASSED", "TOTAL NO OF FAILED", "FINAL RESULT", "DATE & TIME"};

DefaultTableModel model = new DefaultTableModel(columnNames, 0);  

for (Object item : arrayList) {
    Object[] row = new Object[6];

    how to add the element in row ...?

    model.addRow(row);
}
final JTable table = new JTable(model);

Answer 1

你可以维护一个整数 i 并在循环中你可以做

row [i] = item ;

P.S你必须检查null，length等以避免exceptions ......

Answer 2

Object[] row = new Object[number_of_element];

for(int i = 0; i < number_of_object; i++)
    row[i] = (Object)item;

另外，要注意你在for循环中创建行数组，它应该在循环之外
