Yeah I mean in so far that Go is basically Java-like (GC-ed, statically typed, has interfaces, simple language) it could be used there too. Go targets very much the same kind of problem as Java. C# too.

I only have a passing knowledge of Go so I can't comment on it's advantages or disadvantages much, although one of the great strengths of Go (tooling) is also very much a strength of Java (at least in large companies where there will be dev env teams that set up the Java environment for you.)
