Question

write a java statement to input a character from the user through keyboard​

Answer 1

Answer:

Accepting keyboard input in Java is done using a Scanner object.

Consider the following statement

• $Scanner.. console = new.. Scanner(System.in)..$                                                          This statement declares a reference variable named console. The Scanner object is associated with standard input device (System.in).

• To get input from keyboard, you can call methods of Scanner class. For example in following statment nextInt() method of Scanner takes an

• integer and returns to variable x :                                                                                                                                   int x = console.nextInt();                                                                                               EXAMPLE :_$Example :import java.util.Scanner; // Needed for Scanner class/** * This program demonstrates keyboard input. */public class RectangleArea{ public static void main(String[] args) { int length; // To hold rectangle's length. int width; // To hold rectangle's width. int area; // To hold rectangle's area // Create a Scanner object to read input.$
