How can I instantiate multiple objects into a list?

Question

I need to instantiate a list with multiple String objects. I am not allowed to manually add objects 1 by 1.

I tried multiple ways, cannot get method to accept it.

scrambleOrRemove(["TAN", "ABRACADABRA", "WHOA", "APPLE", "EGGS"]);

Method:

public static void scrambleOrRemove(List<String> list)
{
  int length = list.size()-1;
  for(int i=0;i<length;i++)
  {
    String otherword = list.get(i);
    if(scrambleWord(otherword).equals(otherword))
    {
     list.remove(i);
    }

  }

  System.out.println(list);
}

What is `scrambleWord`? And you need an `i--` after calling `list.remove(i)`. — Elliott Frisch, Sep 25 '16 at 02:11
`asList()` or you can use the `addAll()` method too. See here: http://stackoverflow.com/questions/24922011/add-multiple-string-variables-to-arraylist/24922034#24922034 — markspace, Sep 25 '16 at 02:34

Call it like this:

scrambleOrRemove(
  new ArrayList<String>(
     Arrays.asList(
       "TAN", "ABRACADABRA", "WHOA", "APPLE", "EGGS"
     )
  )
);

Now that you have your solution, read the manuals and explain why this works and why it was necessary for your case.

You can use java.util.Arrays.asList() method. So for your example -

Arrays.asList({"TAN", "ABRACADABRA", "WHOA", "APPLE", "EGGS"});

Perhaps not relevant to your example as you are removing elements from your list later but you can also look into ImmutableList of Guava for doing this in general - https://google.github.io/guava/releases/snapshot/api/docs/com/google/common/collect/ImmutableList.html

ImmutableList.of("TAN", "ABRACADABRA", "WHOA", "APPLE", "EGGS");
