数组越界异常

Question

伙计们，我想尝试从http post rerquest解析xml并在arraylist中存储值并在列表视图中显示它。但是有一个错误，如ArrayOutOfBoundsException，解析时没有错误，帖子中没有错误，但我找不到错误的位置？

这是我的代码，请查看并给我建议纠正：

Answer 1

当你得到一个例外时，你也会得到它发生的行号。

我无法确定您的异常发生在哪里，因为我没有您的输入数据，但这似乎是一个问题：

for (int u = 0; u < name.size(); u++) {
    System.out.println(name.get(u));
    System.out.println(value.get(u));
}

您迭代name列表，但也打印出value个项目。
