public static boolean verifyRecords(LinkedList<String> recordList, String order) throws Exception {
/*To check ascending order*/
if("Ascending".equalsIgnoreCase(order) || "A".equalsIgnoreCase(order)) {
String previous = new String();
for(String current : recordList) {
if(current.compareTo(previous) < 0)
return false;
previous = current;
}
} else if("Descending".equalsIgnoreCase(order) || "D".equalsIgnoreCase(order))
{
for(String current : recordList) {
if(current.compareTo(previous) > 0)
return false;
previous = current;
}
}
return true;
}
在这里,我给新的String(),即Empty,字符串以Ascending顺序开头。但是对于降序,应该使用起始字符串来开始降序比较我应该使用什么?
非常感谢任何帮助。

你不需要循环直到最后一个元素,你可以比较任何不平衡的东西,并从那里打破以实现你的结果或验证列表。

您可以使用Collections.reverse(list)进行比较。我们的想法是创建recordList的浅表副本,按降序排序并比较它们。
LinkedList<String> recordList = new LinkedList<String>(Arrays.asList("a","B", "c"));
LinkedList<String> validateList = new LinkedList<String>(recordList);
Collections.sort(validateList); // sorts in ascending order
Collections.reverse(validateList); // reverses the ascending ordered list
System.out.println(recordList.equals(validateList));
