j8 MethodRef #cheatsheet

Need to developer more low-level insights as QQ…

  • Out of the four kinds of method refs, only AA) static-method and BB) specific-instance kinds are popular. The other two types are obscure.
  • q[ :: ] is used in all four kinds
  • I think the static-method kind is most readable and most intuitive. The javadoc tutorial features a BB example that should be implemented as static method IMHO.
  • a lambda expression has parameter types. A method ref has none and must be converted to a lambda expression. Where does compiler infer the parameter types? I think it is inferred from the calling context.
