    Default What the h#$% does this mean

    given the code:

     
      class FingerprintController(...) : FingerprintManagerCompat.AuthenticationCallback() {
            /**
             * Helper variable to get the context from one of the views. The view used is arbitrary. 
             */
            private val context: Context
                get() = errorText.context
     
            private var cancellationSignal: CancellationSignal? = null
            private var selfCancelled = false
     
            private val isFingerprintAuthAvailable: Boolean
                get() = fingerprintManager.isHardwareDetected && fingerprintManager.hasEnrolledFingerprints()
     
            private val resetErrorTextRunnable: Runnable = Runnable {
                errorText.setTextColor(ContextCompat.getColor(context, R.color.hint_color))
                errorText.text = context.getString(R.string.touch_sensor)
                icon.setImageResource(R.drawable.ic_fingerprint_white_24dp)
            }
     
            init {
                errorText.post(resetErrorTextRunnable)
            }
     
            interface Callback { }
        }

    get() = errorText.context

    WHAT DOES THIS MEAN!.
    ive got no idea of why i keep finding unorthodox things in java examples.

    its supposedly from a tutorial to use the fingerprint authentication.

    What language is the code written in? I don't recognize it as java.

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Does the site say what language it is in? Is there a forum for that language?
