Ints asList() function in Java

The asList() method of the Ints class in Java Guava’s returns a fixed-size list backed by the specified array. The syntax is as follows −

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

Here, arr is the array to back the list.

Let us see an example to implement the asList() method of the Ints class −

Example

import com.google.common.primitives.Ints; import java.util.List; class Demo {    public static void main(String[] args) {       int arr[] = { 20, 30, 40, 60, 80, 90, 120, 150 };       System.out.println("Array elements = ");       for(int i = 0; i < arr.length; i++) {          System.out.println(arr[i]);       }       List<Integer> list = Ints.asList(arr);       System.out.println("List = "+ list);    } }

Output

Array = 20 30 40 60 80 90 120 150 List = [20, 30, 40, 60, 80, 90, 120, 150]
