Statements about the code

Report a typo

Take a look at a class Worker. It extends the Thread class.

The class has one boolean field stopped and a function to set the field to true.

class Worker: Thread() {
    var stopped = false

    override fun run() {
        // do some work while stopped is false
    }

    fun stopIt() {
        this.stopped = true
    }
}

The function stopIt will be invoked by other threads like:

worker.stopIt()

Select all correct statements about the given code.

Select one or more options from the list

To make the code stop always, we should add @Volatile to the field declaration

To make the code always stoppable, we should add the const keyword to the field declaration

It will always work fine (= will be stopped)

It's impossible to change the value of the field stopped from other threads

There are no guarantees that the worker will work correctly (= will be always stopped)
