Convert Hexadecimal into Binary and Long

In this section, you will learn to convert the hexadecimal data into the binary and long format. The java.lang package provides the functionality to convert a hexadecimal to binary and long type data.

Code Description:

This program helps you in converting the hexadecimal data into the binary and long. At run time this program asks for a a hexadecimal data and it then converts it into an integer type data. The toBinaryString() method converts an integer data into binary data. And the parseLong() method converts the hexadecimal data into a long type data.

Here is the code of this program:


import java.io.*;

import java.lang.*;



public class HexadecimalToBinaryAndLong{

  public static void main(String[] args) throws IOException{

    BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));

    System.out.println("Enter the hexa value!");

    String hex = bf.readLine();

    int i = Integer.parseInt(hex);

    String by = Integer.toBinaryString(i);

    System.out.println("This is Binary: " + by);

    long num = Long.parseLong(hex,16);

    System.out.println("This is long:=" + num);

  }

}

Output of this program.

C:\vinod\convert>javac HexadecimalToBinaryAndLong.java

C:\vinod\convert>java HexadecimalToBinaryAndLong
Enter the hexa value!
14
This is Binary: 1110
This is long:=20

int i = Integer.parseInt(hex,16);

to include 0-F, not just 0-9

Missing values A-F as input. 0-9 works just fine though.
