我有一个特定的JSON节点,对应于导入org.codehaus.jackson.JsonNode,而不是导入org.codehaus.jackson.map.JsonNode.

[
    {
        "givenName": "Jim",
        "formattedName": "jimJackson",
        "familyName": null,
        "middleName": "none",
        "honorificPrefix": "mr",
        "honorificSuffix": "none"
    },
    {
        "givenName": "john",
        "formattedName": "johnLasher",
        "familyName": null,
        "middleName": "none",
        "honorificPrefix": "mr",
        "honorificSuffix": "none"
    },
    {
        "givenName": "carlos",
        "formattedName": "carlosAddner",
        "familyName": null,

我是熊猫和numpy的新手.我正在运行一个简单的程序

labels = ['a','b','c','d','e'] 
s = Series(randn(5),index=labels)
print(s)

得到以下错误

    s = Series(randn(5),index=labels)   File "C:\Python27\lib\site-packages\pandas\core\series.py", line 243, in
__init__
    raise_cast_failure=True)   File "C:\Python27\lib\site-packages\pandas\core\series.py", line 2950, in
_sanitize_array
    raise Exception('Data must be 1-dimensional') Exception: Data must be 1-dimensional

知道可能是什么问题吗？我正在尝试使用eclipse,而不是使用ipython笔记本.

我正在尝试编写一个代码,它可以分别使用XML或JSON输入并输出JSON或XML.即,如果我给XML它应该给回JSON,如果我给JSON它应该给出XML输出.

我被告知使用Jackson API和JAXB Annotations可以实现这一点.任何人都可以帮我解决这个问题吗？

有没有简单的方法来实现这一目标.

假设我有一个名为POJO的字符串数组,我试图打印所有属性列表,有没有办法轻松实现这一点？

String [] nameofClass;
for(String name:nameofClass)
name.class.getDeclaredFields();

谢谢

为什么这不起作用？

public class AddArray
{
    public static void main(String[] args) 
    {

        int[] x = {1,2,3};
        int[] y = {1,2,3};

        dd(x,y);

        public static void add(int[]a, int[]b)
        {
            int[] sum = new int[a.length];
            for (int i=0; i<a.length; i++)
                sum[i] = a[i] + b[i];
            for (int i=0; i<a.length; i++)
                System.out.println(sum[i]);
        }
    }
}
