Question

The file below is the starter file for the question:

import java.util.Scanner;

public class DecToBin {

public static void main(String[] args) {

System.out.println("Please enter the decimal representation of an integer: ");

Scanner input = new Scanner(System.in);

int decimal = input.nextInt();

String binary = decToBin(decimal);

System.out.printf("The binary representation is %s ", binary);

input.close();

}

public static String decToBin(int decimal) {

// Your code here

In the file, provide code for the method

public static String decToBin(int decimal)

that takes the decimal representation of a nonnegative integer as an int and returns the binary representation of the given integer as a string.

Run the program to test the correctness of your code for the method. The following are some sample runs:      

Please enter the decimal representation of an integer:

The binary representation is 10101

Please enter the decimal representation of an integer:

The binary representation is 100001011100

Please also provide comments for each line of the program.

must also be written in java C++

Explanation / Answer

Hi, Please find my implementation.

import java.util.Scanner;

public class DecToBin {

   public static void main(String[] args) {

       System.out.println("Please enter the decimal representation of an integer: ");

       Scanner input = new Scanner(System.in);

       int decimal = input.nextInt();

       String binary = decToBin(decimal);

       System.out.printf("The binary representation is %s ", binary);

       input.close();

   }

   public static String decToBin(int number) {

       // Your code here

       StringBuffer sBuf = new StringBuffer();

      int temp=0;

      while(number>0){

      temp = number%2;

      sBuf.append(temp);

      number = number / 2;

      }

      return sBuf.reverse().toString();

   }

}

/*

Sample run:

Please enter the decimal representation of an integer:

123

The binary representation is 1111011

Please enter the decimal representation of an integer:

64

The binary representation is 1000000
