Sample Code

String[] friendList = {"Tuan", "Nam", "Lan"};

Arrays.sort(friendList,

(friend01, friend02) ->

Integer.compare(friend01.length(), friend02.length()));

System.out.print(Arrays.toString(friendList));

Output

[Lan, Nam, Tuan]

Multiple lines of code

If your code cannot be written in 1 line, it can be enclosed in {} and your code now should explicitly contain a return statement

Sample Code

String[] friendList = {"Tuan", "Nam", "Lan"};

Arrays.sort(friendList,

(String friend01, String friend02) ->

{

if (friend01.length() > friend02.length())

return -1;

else

return 0;

});
