java - Method for string input to binary string?

Question

Need to make a method for taking an input, num= stdIn.nextLine(); and converting it into a binary string. "public static String toBinary(String num)". In Java. Any ideas? Can only find for int to binary. Needs to be string so user can enter "q" to exit program.

Answer 1

public static String toBinary(String num) {
    int convertedNum = Integer.parseInt(num);
    return Integer.toBinaryString(convertedNum);
}

Note that you should catch possible runtime exceptions because of the integer conversion of the String value.

I hope I helped you!
