Java binary to hex – Java Program for Binary to Hexadecimal
 
 
In this article we will see how to convert Binary to Hexadecimal.
 
Java Program to Convert Binary to Hexadecimal
 
So, before going into the program directly, let’s know about binary and hexadecimal.
 
Binary to hexadecimal java: Binary number mainly consists of only two numbers i.e. 0 and 1. The base address of the binary number is 2. For low voltage signal the value will 0 and for the high voltage signal the value will 1.
 
Hexadecimal:
 
Hexadecimal number basically defines the base of 16 in the number system. This number is basically consists of 16(sixteen) single digits and alphabets like 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E and F. This number is represented by 4(four) bit only.
 
Let’s see different ways to do it.
 
Method-1: Java Program for Binary to Hexadecimal By using toHexString() method
 
In this approach the default method toHexString() is used.
 
import java.util.*; public class BinaryToHex < //binary to decimal convesion int binaryToDecimal(long binary_no) < // for storing the variable conversion int decimal_Number = 0, i = 0; // loop to extract the digits of the binary while (binary_no >0) < //for extraction of the digits decimal_Number += Math.pow(2, i++) * (binary_no % 10); // updating the binary by eliminating // the last digit on division by 10 binary_no /= 10; >// returning the decimal number return decimal_Number; > // method to convert decimal to hexadecimal String decimalToHex(long binary_no) < // variable to store the output of the // binaryToDecimal() method int decimal_Number = binaryToDecimal(binary_no); // converting the integer to the desired // hex string using toHexString() method String hexNumber= Integer.toHexString(decimal_Number); hexNumber = hexNumber.toUpperCase(); return hexNumber; >public static void main(String[] args) < // instantiating the class BinaryToHex ob = new BinaryToHex(); Scanner sc = new Scanner(System.in); System.out.println("Enter the binary number : "); long n = sc.nextLong(); System.out.println("After converting the "+n+" is : "+ob.decimalToHex(n)); >>
 
Output: Enter the binary number : after converting the 1011111 is: 5F
 
Method-2: Java Program for Binary to Hexadecimal By repeatedly getting the remainder
 
In this approach first we will convert the binary number to decimal number. After that continuously dividing and getting the remainder for getting single character for four bit type for the original binary number.
 
import java.util.*; public class BinaryToHex < // conversion of binary to decimal int binaryToDecimal(long binary_no) < // variable declaration int decimal_Number = 0, k = 0; while (binary_no >0) < // extraction of each digit of the binary decimal_Number+= Math.pow(2, k++) * (binary_no % 10); binary_no /= 10; >// for returning the decimal value return decimal_Number; > // method to convert decimal to hex String decimalToHex(long binary_no) < // for storing the variable output // binaryToDecimal() method int decimal_Number = binaryToDecimal(binary_no); // character array to represent double // digit remainders char arr[] = < 'A', 'B', 'C', 'D', 'E', 'F' >; // variable to store the remainder on // division by 16 int remainder, i = 0; // declaring the string that stores the // final hex string String hex_Number = ""; // loop to convert decimal to hex while (decimal_Number != 0) < // calculating the remainder of decimal // by dividing by 16 remainder = decimal_Number % 16; // checking if the remainder is >= 10 if (remainder >= 10) // replacing with the corresponding // alphabet from the array hex_Number = arr[remainder - 10] + hex_Number; else hex_Number = remainder + hex_Number; decimal_Number /= 16; > // returning the hex string return hex_Number; > // Driver Code public static void main(String[] args) < // for instantiating the class BinaryToHex ob = new BinaryToHex(); Scanner sc = new Scanner(System.in); System.out.println("Enter the binary number : "); long n = sc.nextLong(); System.out.println("after converting the "+n+" is : "+ob.decimalToHex(n)); >>
 
Output: Enter the binary number : after converting the 101111111 is: 17F
