Answer 1

Problems with roll:

• You cannot return a value from a constructor. Constructors are used to instantiate an object. You should probably create a field and set it to InRoll.
• If you’re trying to generate a number between 2 and 12 with dice, that’s not the way to do it. You will get an unrealistic distribution where you get more 2’s than normal.
• You cannot invoke a method on a primitive type. You should be using InRoll == someNumber.
• You cannot return a value in a method if its return type is void.
• You did not create a field named InRoll, so you cannot use it in your onMessage method.

Problems with Dice4Cash:

• You cannot access a field that does not exist. You create neither an IntRoll field nor an OpRoll field.

I highly suggest you walk your way through some Java tutorials and learn the language.
