返回值:这个方法返回一个由指定数组支持的固定大小的列表。

例 1:

// Java code to show implementation of
// Guava's Ints.asList() method

import com.google.common.primitives.Ints;
import java.util.List;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {

        // Creating an integer array
        int arr[] = { 1, 2, 3, 4, 5 };

        // Using Ints.asList() method to wrap
        // the specified primitive Integer array
        // as a List of the Integer type
        List<Integer> myList = Ints.asList(arr);

        // Displaying the elements in List
        System.out.println("List of given array: "
                           + myList);
    }
}

输出:

List of given array: [1, 2, 3, 4, 5]

例 2:

// Java code to show implementation of
// Guava's Ints.asList() method

import com.google.common.primitives.Ints;
import java.util.List;

class GFG {

    // Driver's code
    public static void main(String[] args)
    {
        // Creating an integer array
        int arr[] = { 3, 5, 7 };

        // Using Ints.asList() method to wrap
        // the specified primitive Integer array
        // as a List of the Integer type
        List<Integer> myList = Ints.asList(arr);

        // Displaying the elements in List
        System.out.println("List of given array: "
                           + myList);
    }
}

输出:

List of given array: [3, 5, 7]
