Question

Java

How to write a java console application that will ask the user for a number, which will then output to the console in hexadecimal form?
For example, the user entered the number 10, and the application will display this number, only in hexadecimal form?
If this can be done, please tell me how.

Answer 1

import java.util.Scanner;

public class myClass {

    public static void main(String[] args) {
        Scanner scanner=new Scanner(System.in);
        System.out.println("Введите число: ");
        int n=scanner.nextInt();

        System.out.println("В шестнадцаричном счислении: " +Integer.valueOf(String.valueOf(n), 16));




    }

}

Answer 2

Approximate console version
1) create BufferedReader reader .....
2) get data from readera and convert to
int int dec = Integer.parseInt(reader.readLine())
3) output data to console and convert System. out.println( Integer.toString(dec, 16).toUpperCase())
Of course, you still need to wrap it in a try-catch. And close I/O streams
