Write a Java program to convert a decimal number to binary numbers

Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
public class Javaexcercise {
      public static void main(String args[])
    {
        int decimalnum, quot, i=1, j;
        int bin_num[] = new int[100];
        Scanner scan = new Scanner(System.in);
 
        System.out.print("Enter a Decimal Number : ");
        decimalnum = scan.nextInt();
 
        quot = decimalnum;
 
        while(quot != 0)
        {
            bin_num[i++] = quot%2;
            quot = quot/2;
        }
 
        System.out.print("Binary number is: ");
        for(j=i-1; j>0; j--)
        {
            System.out.print(bin_num[j]);
        }
        System.out.print("\n");
    }
}

  1. package myfirstpackage;

    import java.util.Scanner;
    public class experiment {

    public static void main(String[] args) {
    int num, harry;
    Scanner sc = new Scanner(System.in);
    System.out.println(“Please Enter the Decimal Number :”);
    num = sc.nextInt();

    while (num>0)
    {
    harry = num % 2;
    System.out.print(harry);
    num = num/2;

    }
    }
    }

    i got the same result of Decimal to Binary Number.
    I think so that it is easy code. And main thing is that i performed this code without having array in my code. Rather than, i executed the same ans using just two numbers. If there is any error, so please email me:
