Java program to convert decimal number to binary

In this program, we are going to share Java program to convert decimal number to binary with the output. If you are a Java beginner and want to start learning the Java programming, then keep your close attention in this tutorial as I am going to share how to write a Java program to convert a decimal number to binary.

Java program to convert decimal number to binary with the output

Copy the below Java program and execute it with the help of Javac compiler. At the end of this program, We have shared the output of this program.

public class DecimalBinaryProgram {

    public static void main(String[] args) {
        int num = 5;
        long binary = convertDecimalToBinary(num);
        System.out.printf("%d in decimal = %d in binary", num, binary);
    }

    public static long convertDecimalToBinary(int n)
    {
        long binaryNumber = 0;
        int remainder, i = 1, step = 1;

        while (n!=0)
        {
            remainder = n % 2;
            System.out.printf("Step %d: %d/2, Remainder = %d, Quotient = %d\n", step++, n, remainder, n/2);
            n /= 2;
            binaryNumber += remainder * i;
            i *= 10;
        }
        return binaryNumber;
    }
}

public class DecimalBinaryProgram {

public static void main(String[] args) {

int num = 5;

long binary = convertDecimalToBinary(num);

System.out.printf("%d in decimal = %d in binary", num, binary);

}

public static long convertDecimalToBinary(int n)

{

long binaryNumber = 0;

int remainder, i = 1, step = 1;

while (n!=0)

{

remainder = n % 2;

System.out.printf("Step %d: %d/2, Remainder = %d, Quotient = %d\n", step++, n, remainder, n/2);

n /= 2;

binaryNumber += remainder * i;

i *= 10;

}

return binaryNumber;

}

Program Output

Step 1: 5/2, Remainder = 1, Quotient = 2
Step 2: 2/2, Remainder = 0, Quotient = 1
Step 3: 1/2, Remainder = 1, Quotient = 0
5 in decimal = 101 in binary
