Guava’s Ints.asList() returns a fixed-size list backed by the specified array.

Syntax:

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

Parameters: This method takes the array as parameter which is the array to back the list.

Return Value: This method returns a fixed-size list backed by the specified array.

Example 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);
    }
}
Output:
List of given array: [1, 2, 3, 4, 5]

Example 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);
    }
}
Output:
