»
This is a Java Program to Convert Hexadecimal to Binary.

We make a class with two methods one for input and other for conversion and access this by object of this class. We first take the input as HexaDecimal from user. We define a method as convert() to convert the user’s input to Binary.

Here is the source code of the Java Program to Convert Hexadecimal to Binary. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  3.      {
  4.                  Scanner scan;
  5. 	int num;
  6. 	void getVal()
  7.                      {
  8.         		System.out.println("HexaDecimal to Binary");
  9. 		scan = new Scanner(System.in);
  10. 		System.out.println("\nEnter the number :");
  11. 		num = Integer.parseInt(scan.nextLine(), 16);
  12. 	    }
  13. 	void convert()
  14.     	   {
  15. 		String binary = Integer.toBinaryString(num);
  16. 		System.out.println("Binary Value is : " + binary);
  17. 	   }
  18.      }
  19. class MainClass
  20. {
  21.          public static void main(String args[])
  22.             {
  23. 	Hexa_Binary obj = new Hexa_Binary();
  24. 	obj.getVal();
  25. 	obj.convert();
  26.             }
  27. }

Output:
