-----------> This code needs to have the binary function handle a negative number.

import java.util.Scanner;

public class BinaryTest {

public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("Enter a deciaml number: "); int binaryNumber = scan.nextInt(); System.out.println("Binary String is "+binary(binaryNumber)); } public static String binary(int binaryNumber){ if(binaryNumber<=0){ return "Invalid Input. Input must be greather than 0."; } String s = ""; do { s = s + (binaryNumber & 1); binaryNumber = binaryNumber >> 1; } while (binaryNumber > 0); return new StringBuffer(s).reverse().toString(); }

}
