Write a program, in Java, to convert from binary to decimal andfrom from binary to hexadecimal. Please use instance variables,preferably strings. The program must do the conversion withoutusing any of the built-in functions from the Java library. Thankyou in advance.

Effectively I need the code to look like the following, except Ineed it to be done for binary to decimal/hexadecimal:

HexaDecimal to Binary conversion in Javaimport java.util.Scanner; public class Hexa_Binary {                Scanner scan;        int num;                void getVal() {                                System.out.println("HexaDecimal to Binary");                scan = new Scanner(System.in);                                System.out.println("Enter the number :");                num = Integer.parseInt(scan.nextLine(), 16);        }                void convert() {                                String binary = Integer.toBinaryString(num);                                System.out.println("Binary Value is : " + binary);        }} class MainClass {                public static void main(String args[]) {                                Hexa_Binary obj = new Hexa_Binary();                                obj.getVal();                obj.convert();        }}
