Guava的 Ints .asList() 返回一个由指定数组支持的固定大小的列表。

语法:

public static List<Integer> 
    asList(int[] array)

参数： 该方法以数组为参数，数组是用来支持列表的。

返回值： 该方法返回一个由指定数组支持的固定大小的列表。

示例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]
