如何通过LinkedHashMap迭代到第x个元素？

Question

将LinkedHashMap迭代到第x个元素的最佳方法是什么？

for (Entry<String, Integer> entry : existingFile.entrySet() )
            {

                builder.append("{" + entry.getKey() + "," + entry.getValue() + "}   ");

            }

这遍历所有元素,我怎么能阻止它在第5个元素？

使用柜台:

int counter = 0;

for (Entry<String, Integer> entry : existingFile.entrySet() )
{
    if (counter == 5)
        break;

    builder.append("{" + entry.getKey() + "," + entry.getValue() + "}   ");
    counter++;
}
