Converting .java file to kotlin (.kt) file ( I am using Android Studio Flamingo )

• Goto top bar in Android Studio
• Click or open java file you want to convert
• Select Code ->Select Convert java file to kotlin OR click java file and press Ctrl+Alt+Shift+K to convert
• After converting to kotlin file, you will encounter errors while referencing UI component in kotlin.
• You need to reference views as below

Code Snippet:

class RegisterActivity : AppCompatActivity(){

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

    val email: EditText= findViewById(R.id.editTextEmail)
    val pass: EditText= findViewById(R.id.editTextPass)
    val register: Button= findViewById(R.id.register)

    register.setOnClickListener {  }

    ...
    ...
}
