Question:

How do I convert int[] into List in Java?

Code:

import java.util.*;
 
public class IntToList {
 
  public static void main(String[] args) {
 
    int[] ints = new int[]{1,2,3,4,5,6,7,8,9};
 
    List<Integer> list = new ArrayList<Integer>();
    for (int n = 0; n < ints.length; n++) {
        list.add(ints[n]);
    }
 
    System.out.println("int[] ints: " + Arrays.toString(ints));
 
 
    System.out.print("List<Integer> list: ");
    for(int i=0;i<list.size();i++){
      System.out.print(list.get(i) + " ");
    }
    System.out.println();
  }
}

Output:

$ java IntToList
int[] ints: [1, 2, 3, 4, 5, 6, 7, 8, 9]
List list: 1 2 3 4 5 6 7 8 9
