Binary to HexaDecimal Program in Java

Convert Binary to HexaDecimal Program in Java

There are two way to convert binary to hexadecimal in java using predefined method and other is create own logic.

import java.util.Scanner;
 
public class BinaryToHexaDecimal
{
Scanner scan;
int num;
	
void getVal() 
{
System.out.println("Binary to HexaDecimal");
scan = new Scanner(System.in);
		
System.out.println("\nEnter the number :");
num = Integer.parseInt(scan.nextLine(), 2);
}
	
void convert() 
{
		
String hexa = Integer.toHexString(num);
System.out.println("HexaDecimal Value is : " + hexa);
}
}
 
class MainClass 
{
	
public static void main(String args[]) 
{
Binary_Hexa obj = new Binary_Hexa();
obj.getVal();
obj.convert();
}
}

Binary to HexaDecimal

Enter the number :
1010
HexaDecimal Value is : a

import java.util.Scanner;

public class BinaryToHexaDecimal
{
 public static void main(String args[])
 {
  int binnum, rem;
  String hexdecnum="";
        
  // digits in hexadecimal number system
        
   char hex[]={'0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'};
   Scanner scan = new Scanner(System.in);
		
   System.out.print("Enter Binary Number : ");
   binnum = scan.nextInt();
		
   // converting the number in hexadecimal format
   while(binnum>0)
   {
    rem = binnum%16;
    hexdecnum = hex[rem] + hexdecnum;
     binnum = binnum/16;
   }
		
   System.out.print("Equivalent Hexadecimal Value of " +binnum+ " is :\n");
   System.out.print(hexdecnum);
 }
}

Enter Binary Number: 1101

Equivalent Hexadecimal Value of 1101 is: 44D
