CallOnPrimitive
DRAFT

Misconception:

It is possible to call a method on values of primitive types.

One can invoke a method on primitive values

Methods can only be called on objects. That is, o.m() works only if o is of a reference type.

Integer i = ...;
String s = i.toString(); // ok

int i = ...;
String s = i.toString(); // not possible in Java

public static int f(int x) {
  ...
}

int v = ...;
v.f; // should be f(v)

(v-1).f // should be f(v-1)

Java

Correction
Here is what's right.
