Arrays.asList(array) 和 new ArrayListInteger(Arrays.asList(array)) 之间的区别

Java
public class ArrayToListExample {
    public static void mAIn(String[] args) {
        int[] arr = {1, 2, 3, 4, 5};
        
        // 使用Arrays.asList(array)方法将数组转换为List
        List<Integer> list = Arrays.asList(arr);
        System.out.println("转换为List后的元素个数：" + list.size());
        
        // 使用new ArrayList<Integer>(Arrays.asList(array))方法将数组转换为ArrayList
        ArrayList<Integer> arrayList = new ArrayList<Integer>(Arrays.asList(arr));
        System.out.println("转换为ArrayList后的元素个数：" + arrayList.size());
        
        // 尝试对Arrays.asList(array)方法返回的List进行添加和删除操作
        try {
            list.add(6); // 抛出UnsupportedOperationException异常
        } catch (UnsupportedOperationException e) {
            System.out.println("对Arrays.asList(array)方法返回的List进行添加操作时抛出异常：" + e.getMessage());
        }
        
        try {
            list.remove(0); // 抛出UnsupportedOperationException异常
        } catch (UnsupportedOperationException e) {
            System.out.println("对Arrays.asList(array)方法返回的List进行删除操作时抛出异常：" + e.getMessage());
        }
    }
}
