// Java program to convert decimal to binary using bitwise operator
public class Main {
    public static void main(String[] args) {
        // Step-1 Declare and initialize the decimal number
        int num = 10;

        // Step-2 Check if the number is zero
        if (num == 0) {
            System.out.println("Binary representation: 0");
            return;
        }

        // Step-3 Store result using bitwise operations
        String binary = "";
        for (int i = 31; i >= 0; i--) {
            int bit = (num >> i) & 1;
            binary += bit;
        }

        // Step-4 Trim leading zeros
        binary = binary.replaceFirst("^0+(?!$)", "");

        // Step-5 Output result
        System.out.println("Binary representation: " + binary);
    }
