Thread: 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:

to get highlighting and preserve formatting.

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