Java Tutorial Java Exercises Data Structures

In this program, you'll learn to print a number entered by the user in Java. The Char is stored in a variable using System.in, and is displayed on the screen using System.out.







import java.util.Scanner; public class Test { public static void main(String[] args) { char c; Scanner p=new Scanner(System.in); System.out.print("Enter any character:"); c =p.next().charAt(0); System.out.println("Display enter char:" + c); } }




Output:

Enter a character:c Display enter char:c

In this program, an object of Scanner class, reader is created to take inputs from standard input, which is keyboard.

Then, Enter a number prompt is printed to give the user a visual cue as to what they should do next.

op.next().charAt(0) then reads all entered Char from the keyboard unless it encounters a new line character \n (Enter).

If you enter any character which is not an Char, the compiler will throw an InputMismatchException.

Finally, number is printed onto the standard output (System.out) - computer screen using the function println().
