I am trying to print out my "numsList" but it prints out the memory address instead of the list elements. I have another list with String as my data type and it works fine. Is this an issue with Java 8? Thank you for any insight.
Here is my code:
String names = {"Rahul", "Utkarsh", "Shubham", "Neelam"};
List namesList = Arrays.asList(names);
System.out.println(namesList);
int nums = {3, 6, 2, 5, 8, 2, 11, 72, 7, 3, 19};
List numslist = Arrays.asList(nums);
System.out.println(numslist);
Another issue I just found while typing this is that if I specify the data type after List I get an error with numsList.
Here's what I mean;
String names = {"Rahul", "Utkarsh", "Shubham", "Neelam"};
List<String> namesList = Arrays.asList(names);
System.out.println(namesList);
int nums = {3, 6, 2, 5, 8, 2, 11, 72, 7, 3, 19};
List<Integer> numslist = Arrays.asList(nums);
System.out.println(numslist);

You can't print a List.You can print an element of a List (or Array).You can also iterate an list (or array) , does those two make sense?

@TsakiroglouFotis yes you can print a list. The list class comes with a toString method. toString worked on my List that has Strings but not nums.
