Java Program To Print Integer Using User Input

Chapter: Java Basics Last Updated: 25-08-2017 08:02:33 UTC

Program:

            /* ............... START ............... */
                
import java.util.Scanner;

public class JavaPrintInteger {

	public static void main(String[] args) {

		Scanner reader = new Scanner(System.in);
		System.out.print("Enter a number: ");

		int number = reader.nextInt();

		System.out.println("You entered: " + number);
	}

}
                /* ............... END ............... */
        

Output

Enter a number: 5
You entered: 5

Notes:

• Scanner class reader is used to created to take inputs from standard input, which is keyboard.
• reader.nextInt() reads all entered integers from the keyboard unless it encounters a new line character \n (Enter).
• If you enter any character which is not an integer, the compiler will throw an InputMismatchException.
