Convert Decimal to Binary, Octal and Hexadecimal Java

PROGRAM TO CONVERT DECIMAL TO BINARY, OCTAL AND HEXADECIMAL

1. class Convert

2. {

3.     Scanner scan;

4.     int num;

5.     void getVal()

6.      {

7.           System.out.println("Decimal to HexaDecimal,Octal and Binary");

8.           scan = new Scanner(System.in);

9.           System.out.println("\nEnter the number :");

10.           num = Integer.parseInt(scan.nextLine());

11.      }

12.     void convert()

13.       {

14.            String hexa = Integer.toHexString(num);

15.            System.out.println("HexaDecimal Value is : " + hexa);

16.            String octal = Integer.toOctalString(num);

17.            System.out.println("Octal Value is : " + octal);

18.            String binary = Integer.toBinaryString(num);

19.            System.out.println("Binary Value is : " + binary);

20.        }

21. }

22. class Decimal_Conversion

23. {

24.    public static void main(String args[])

25.     {

26.         Convert obj = new Convert();
