Question

Which statement displays a message on the user interface that says, "Hello"?

A. textView.setText("Hello");
B. editText.displayMessage("Hello");
C. showMessage("Hello");
D. Toast.makeText(context, "Hello", Toast.LENGTH_SHORT).show();

Answer 1

The correct statement to display the message "Hello" on the user interface of an Android application is D. Toast.makeText(context, "Hello", Toast.LENGTH_SHORT).show(); which creates a brief pop-up notification called a Toast.

Step-by-step explanation:

The question is asking which statement in a given programming language would display a message saying "Hello" on the user interface. Considering the options provided, the correct statement for displaying a message in the user interface of an Android application using a toast is:

D. Toast.makeText(context, "Hello", Toast.LENGTH_SHORT).show();

This line of code creates a small pop-up notification, commonly known as a Toast, that briefly shows the message "Hello" to the user. Options A, B, and C either refer to methods that don't exist or methods that serve different purposes in Android development.
