9行代码体现集合框架中的一个小细节

String[] strs = {"string--01", "string--02", "string--03", "string--04"};
List<String> strsList = Arrays.asList(strs);
//以下语句输出：[string--01, string--02, string--03, string--04]
System.out.println(strsList);
 
int[] ints = {2, 3, 4, 5};
List<int[]> intsList = Arrays.asList(ints);
//以下语句输出：[[I@c17164]
System.out.println(intsList);
 
Integer[] intes = {2, 3, 4, 5};
List<Integer> intesList = Arrays.asList(intes);
//以下语句输出：[2, 3, 4, 5]
System.out.println(intesList);
