...h it from a field? For example, how would you want to write:
public class Foo {
private static final int widgets;
static {
int first = Widgets.getFirstCount();
int second = Widgets.getSecondCount();
// Imagine more complex logic here which really used first/second

Why shouldn't Java enum literals be able to have generic type parameters?

struct foo {
char a;
int b;
};
With a typical 32-bit machine, you'd normally "want" to have 3 bytes of padding between a and b so that b will land at a 4-byte boundary to maximize its access speed (and that's what will ty...
