java - 如何将这段代码转换为循环？

Question

如何将此代码转换为循环？我已将 top 定义为 NodeString 类型的实例变量

    NodeString temp1 = top.getNext().getNext().getNext().getNext().getNext();
    NodeString temp2 = top.getNext().getNext().getNext().getNext();
    NodeString temp3 = top.getNext().getNext().getNext();
    NodeString temp4 = top.getNext().getNext();
    NodeString temp5 = top.getNext();
    NodeString temp6 = top;

    result.add(temp1.getData());
    result.add(temp2.getData());
    result.add(temp3.getData());
    result.add(temp4.getData());
    result.add(temp5.getData());
    result.add(temp6.getData());

您可以构建一个数组，然后向后迭代它。就像是，

NodeString[] arr = { top, arr[0].getNext(), arr[1].getNext(), 
        arr[3].getNext(), arr[4].getNext(), arr[5].getNext() };
for (int i = arr.length - 1; i >= 0; i--) {
    result.add(arr[i].getData());
}
