Converting decimal to binary in Java

Question

I\'m trying to write a code that converts a number to binary, and this is what I wrote. It gives me couple of errors in Eclipse, which I don\'t understand. What\'s wrong wit

Answer 1

For starters you've declared a method inside a method. The main method is the method that runs first when you run your class. ParseInt takes a string, whereas args is an Array of strings, so we need to take the first (0-based) index of the array.

mod is not a valid operator, the syntax you wanted was %

You can use System.out.print to print on the same line rather than println

Try these corrections and let me know how you get on:

 public class NumberConverter {
  public static void main(String[] args) {
  int i = Integer.parseInt(args[0]);
  Binary(i);
 } 

 public static void Binary(int int1){
    System.out.println(int1 + " in binary is ");
    do {
        System.out.print(int1 % 2);
        int1 /= 2;
    } while (int1 > 0);


 }
}
