Answer 1

Try using Integer.parseInt(binOutput, 2) instead of Integer.parseInt(binOutput)

Answer 2

Ted Hopp beat me to it, but here goes anyway:

jcomeau@intrepid:/tmp$ cat test.java; java test 000010001010011
public class test {
 public static void main(String[] args) {
  for (int i = 0; i < args.length; i++) {
   System.out.println("The value of " + args[i] + " is " +
    Integer.toHexString(Integer.parseInt(args[i], 2)));
  }
 }
}
The value of 000010001010011 is 453
