java - 使用集合比较字符串数组

Question

我有两个字符串数组 a,b。

String a [] = {"one","two","three"};
String b [] = {"one","Two","Three","four"};

我需要检查两个数组是否相同，不区分大小写。 我知道，以下代码非常适合区分大小写。

List <String> l1 = Arrays.asList(a);
List <String> l2 = Arrays.asList(b);
System.out.println(l2.containsAll(l1));  

有没有其他方法可以使用集合比较两个字符串数组(不区分大小写)？

Answer 1

最后，我使用了 TreeSet 和不区分大小写的比较器。

示例:

 String [] oldVal = {"one","two","three","Four"};
 String [] newVal = {"one","Two","Three","four"};

 Set <String> set1 = new TreeSet <String> (String.CASE_INSENSITIVE_ORDER);
 Set <String> set2 = new TreeSet <String> (String.CASE_INSENSITIVE_ORDER);

 set1.addAll(Arrays.asList(oldVal));
 set2.addAll(Arrays.asList(newVal));

 System.out.println("--Using Tree Set --- "+ set1.containsAll(set2));  // Return True

谢谢大家..
