Criticism-remarks on the enclosed java code

The enclosed Java code was suppose to address the following problem, where I require in giving comments/criticism/remarks if possible with respect to the Java coding standards.
Problem Details: Write a Java program which defines two unconstrained arrays of user defined length n, that contain n Random numbers each and which outputs the addition of pairs of elements.  For example, given {1, 2, 3} and {4, 5, 6} the output would be {5, 7, 9}.
