I assume you were compiling "scratch.java", so looking at the error:

scratch.java:4: error: class, interface, or enum expected
String[] friends={
^

You can see it is pointing to a String declaration and complaining that it was expecting a class (or something similar). A Java variable must belong to some class, but this one (and the following one) does not. Did you perhaps intend to have them as part of a "main" class?
