Получил рабочий код на Kotlin, прошу знающего человека перевести данный код в Java

class MainActivity : AppCompatActivity() {

val SELECT_PHOTO = 1234

lateinit var prefernces: SharedPreferences

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    prefernces = getSharedPreferences("APP", Context.MODE_PRIVATE)

    val uriString = prefernces.getString("image_uri", "")

    if (uriString != null) {
        iv_test.setImageBitmap(bitmapFromUri(Uri.parse(uriString)))
    }

    btn_pick.setOnClickListener {
        val intent = Intent(Intent.ACTION_OPEN_DOCUMENT)
        intent.setType("image/*")
        startActivityForResult(intent, SELECT_PHOTO)
    }
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == SELECT_PHOTO && resultCode == Activity.RESULT_OK) {
        iv_test.setImageURI(data?.data)
        prefernces.edit().putString("image_uri", data?.data.toString()).apply()
    }


}

private fun bitmapFromUri(uri: Uri): Bitmap? =
    contentResolver.openFileDescriptor(uri, "r")?.fileDescriptor?.let {
        BitmapFactory.decodeFileDescriptor(it)
    }
}
