Given you've listed utility methods for two Object methods, equals and
hashCode, toString seems an obvious one to handle as well:
public static String toString(Object o)
throws IllegalAccessException
{
Class<?> c = o.getClass();
StringBuilder b = new StringBuilder(c.getName());
b.append("[");
for (Field f : c.getDeclaredFields())
{
f.setAccessible(true);
b.append(f.getName() + "=" + f.get());
b.append(",");
}
b.replace(b.length() - 1, b.length(), "]");
return b.toString();
}
Maybe there's also a useful utility implementation of clone too, but I
can't think of one offhand.
Arghhh,
b.append(f.getName() + "=" + f.get());
shoud be
b.append(f.getName()).append("=").append(f.get(o));
And I think there is a problem if the object has no field.
