Go Go Java Developer
summary
Compares Java and Go with concrete examples: builds a native executable (1–2MB) and shows goroutines calling C via cgo that print thread ids; demonstrates arrays are values (assignment copies) while slices vs arrays share backing storage until append forces a copy; shows functions returning multiple values and the error as last value convention instead of exceptions; explains implicit interfaces, composition instead of inheritance, no method overloading, go fmt for enforced style, and notes generics just landed but aren’t covered.
