How to assign array string to array object

I have something like this :

List<Page> result = new ArrayList<Page>();

Page is a class with 3 string variables;

I have an array as such :

List<String[]> output = new ArrayList<String[]>();

Which is populated like this in a loop:

String[] out = new String[3];   
out[0] = "";
out[1] = "";
out[2] = "";

then added to output: output.set(i, out);

How can I assign output (type:String) to result (type:Page)?

I am guessing you are looking for something like this (code requires Java 8 but can be easily rewritten for earlier versions using loop)

List<String[]> output = new ArrayList<String[]>();
// populate output with arrays containing three elements 
// which will be used used to initialize Page instances
//...

List<Page> result = output.stream()
                          .map(arr -> new Page(arr[0], arr[1], arr[2]))
                          .collect(Collectors.toList());
