Java program to convert Decimal Number to Binary Number

I was reading the first chapter of my class eleventh textbook. While reading the chapter, I came across a topic "Conversion of Decimal Number System to Binary Number System". In that chapter, I found the method of converting the decimal number to the binary number.

Decimal number system means the number system which is base 10 or uses 10 digits. Like the one we use in maths with digits from 0 to 9.

Binary Number system means the number system that uses the base 2 or only 2 digits. The number system of 0s and 1s are called Binary Number System, which is also the language of computers. In programming, 0 means off or false and 1 means true or on.

The method for converting the decimal number to binary number is: 

First the number is divided by 2 and the remainder whether it is 0 or 1 is noted. The first remainder is called Least Significant Bit (LSB). Then the quotient of the number is again divided by 2 and the remainder is noted. This process is repeated till the quotient becomes zero. The last remainder noted before the quotient became zero is called Maximum Significant Bit (MSB).

I made this program with a single while loop which runs till the number which is input by the user becomes zero. Inside the loop, the remainder is found out with modulus, and it is noted as a string. 

At last, all the remainder is added to another variable from left to right, as the first remainder (LSB) will come last and last remainder (MSB) will come first.

 // Converter from decimal number to binary number

// Method: Divide number by 2 and note the remainder. First remainder will be LSB. Now, take the quotient and divide again by 2. Repeat the process till quotient becomes 0. The last remainder will be MSB. Arrange from MSB to LSB.


import java.util.*;

class Converter {

    public static void main(String[] args) {

        Scanner in = new Scanner(System.in);

        int n;int p; String a; String s="";

        

        System.out.println("Enter decimal number");

        n = in.nextInt();

        while(n>0){

            p = n%2;

            a = String.valueOf(p);

            s = p+s;

            n=n/2;

        }

        System.out.println("Binary number:" + s);

        

    }

}

Abhisara - the Tryst Notes

Image
Upagupta, the disciple of Buddha, lay asleep in the dust by thr city wall of Mathura. Lamps were all out, doors were all shut, ans stars were all hidden by the murky sky of August. Whose feet were those tinkling with anklets, touching his breast of a sudden? He woke up startled, and the light from a woman's lamp fell on his forgiving eyes. It was Vasavadatta the dancing girl, starred with jewels, Clouded with a pale blue mantle, drunk with the wine of her youth. She lowered her lamp and saw the young face, austerely beautiful. 'Forgive me, young ascetic,' said the woman, 'Graciously come to my house. The dusty earth is not a fit bed for you.' The young ascetic answered, 'Woman, go on your way; When the time is ripe I will come to you.' Suddenly the black night showed its teeth in a flash of lightning.  The storm growled from the corner of the sky, and the woman trembled in fear. A year had not yet passed. It was eveing of a day in April, in the Spring. The b...

Summers are getting hotter with each passing year Essay on "Summers are becoming hotter with each passing year. Write a description of one such very hot day. What did you see and hear as you walked outside? How were birds and animals affected?" India is famous all around the world for its different seasons and extreme as well as pleasant climate. The unique features of the Indian subcontinent are found nowhere else. India mainly experiences five seasons Spring, Summer, Monsoon, Autumn and Winter. Summer is considered the best among other seasons by the Indians, but its popularity is decreasing drastically each day as the temperatures are constantly increasing because of climate change. Summer is when the country experiences most death because of extreme weather conditions. It is becoming unbearable for the people as the day temperatures outside reach 50°C. Summer was often associated with fun and enjoyment, but that is not the case anymore. Summers are one of the most excitin...
