RFR 8028516 Java doc error in Int/Long/Double/Stream.peek

[Paul Sandoz]

Hi,

https://bugs.openjdk.java.net/browse/JDK-8028516

An attendee of the Devoxx lambda hackathon spotted some doc bugs in code samples of the stream peek methods.

I updated those samples to be stand alone samples and verified they compile.

Paul.
