alice-teacher Alice 3 NetBeans Do-Together code issue

[Carlos Bovell]

Hi,

We ran into a problem where we tried typing the doTogether syntax directly in MyFirstMethod in NetBeans. We received an error saying that the doTogether nethod is not recognized:

C:\Users\cbovell\Documents\NetBeansProjects\PutFiveNumbersInOrder_starter_22\src\Scene.java:25: error: cannot find symbol
            doTogether(() -> {
  symbol:   method doTogether(()->{ this[...]0); },()->{ this[...]0); },()->{ this[...]0); },()->{ this[...]0); })
  location: class Scene

But when we drag over the control structure from the palette panel with the same exact syntax (honest!) it does work. Why would that be? What does dragging the doTogether over from the palette panel do that typing in the code does not do for NetBeans?

This is the code we typed:

        {
            doTogether(() -> {
                this.dolphin.turn(TurnDirection.LEFT, 2.0);
            }, () -> {
                  this.dolphin2.turn(TurnDirection.LEFT, 2.0);
            }, () -> {
                    this.dolphin3.turn(TurnDirection.LEFT, 2.0);
            }, () -> {
                this.dolphin4.turn(TurnDirection.LEFT, 2.0);
            });
        }

This is the code from the dragged doTogether control structure:

        doTogether(() -> {
            //TODO: Code goes here
            this.dolphin.turn(TurnDirection.LEFT, 2.0);
        }, () -> {
            //TODO: Code goes here
            this.dolphin2.turn(TurnDirection.LEFT, 2.0);
        }, () -> {
            //TODO: Code goes here
            this.dolphin3.turn(TurnDirection.LEFT, 2.0);
        }, () -> {
            //TODO: Code goes here
            this.dolphin4.turn(TurnDirection.LEFT, 2.0);
        });

Thank you for taking my questions.
