我有一个用于JTable的多维数组。但它并没有在JTable中正确显示数据，而是在每一行上从上到下显示：

但是我希望它从左到右显示每个数据而不是从上到下显示
所以应该是这样的：
nidRbc INTEGER RBC 1 1 1 0 NULL 0:16382
maxRouteLength NUMBER:3 Maximum 1 1 2 0 50 ###.###
minRouteLength INTEGER . ... . etc etc..
这是我现在的代码：
// Create a list of node and compile the xpath expression
NodeList nodeList = (NodeList) xPath.compile(expression).evaluate(
xmlDocument, XPathConstants.NODESET);
System.out.println("nodelist length : " + nodeList.getLength());
System.out.println("constant length : "
+ constants.getParamColumns().length);
// Create a new string for the array
arr = new String[nodeList.getLength()][constants.getParamColumns().length];
// Loop through the list and save the data in a string array.
for (int i = 0; i < nodeList.getLength(); i++) {
for (int j = 0; j < constants.getParamColumns().length; j++) {
System.out.println("content : "
+ nodeList.item(i).getTextContent());
arr[i][j] = nodeList.item(i).getTextContent();
// System.out.println("Param : " + Arrays.toString(arr));
}
}
答案 0 :(得分：0)
如果要反转索引顺序，只需反转索引顺序：
NodeList nodeList = (NodeList) xPath.compile(expression).evaluate(xmlDocument,XPathConstants.NODESET);
System.out.printf("Nodelist Length:%1$d%nConstant Length:%2$d%n",
nodeList.getLength(), constants.getParamColumns().length);
arr = new String[constants.getParamColumns().length][nodeList.getLength()];
for(int i = 0; i < nodeList.getLength(); i++)
for(int j = 0; j < constants.getParamColumns().length; j++)
System.out.printf("Content:%1$s%n", arr[j][i]=nodeList.item(i).getAttributes().item(j));
数组索引是从左到右关联的，这意味着首先解析最左边的索引。因此，在多维数组中，可以写array[rowNumber][columnNumber]。
答案 1 :(得分：0)
这是解决方案：
for (int i = 0; i < nodeList.getLength()
/ constants.getParamColumns().length; i++) {
for (int j = 0; j < constants.getParamColumns().length; j++) {
arr[i][j] = nodeList.item(
j + (i * constants.getParamColumns().length))
.getTextContent();
}
}
