VoidMethodReturnsValue
DRAFT

Misconception:

A method that has the return type void can contain a return statement that returns a value.

Incorrect

A method with void return type can return a value

Correct

A method with void return type cannot return a value

Correction
Here is what's right.

If a method’s return type is void, then the method cannot return any value.

It could be that this misconception appears because students first learned pure functional programming, where every function would return a value.

Example occurrence of this misconception:

class C {
  private int field;
  public void modify(int value) {
    return field + value; // believes "return" means "do what the name of the method says"?
  }
}
