Convert Byte to Hexadecimal
In this section, We are going to convert a byte value into a hexadecimal number. The package java.lang provides the functionality for this conversion.
Code Description: This program takes a byte number from console as input and converts it into the hexadecimal by using the toHexString() method. The method Integer.parseInt() takes a string as input and converts it into an integer number.
Here is the code of this program
import java.io.*;
import java.lang.*;
public class ByteToHexa{
public static void main(String[] args) throws IOException{
BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the byte number:");
byte b =(byte)6;
String str = buff.readLine();
int i =Integer.parseInt(str);
String hexString = Integer.toHexString(i);
System.out.println("Hexa is:=" + hexString);
}
}
Output this program.
