Answer 1

import java.util.*;
public class ArrayAsListDemo {
public static void main(String[] args) {
Integer[] arr = {1, 3, 5, 7, 9};
List<Integer> lis = Arrays.asList(arr);
System.out.println(lis);
}
}

以String 数组举例吧：
String[] s = {"a","b","c"};
List<String> list = new ArrayList <String> ();
for(int i = 0;i < s.length;i++){
list.add(s[i]);
}

Answer 3

例如：
int [] buffer = {1,2,3,4,5};
ArrayList<Integer> list = new ArrayList(Arrays.asList(buffer));

Answer 4

List<E> list=new ArrayList<E>();
list.add("new出来的对象");
