Quick and dirty to convert decimal to binary

Binary.java

public static String binary(int input){
        StringBuilder builder = new StringBuilder();
        int numerator = input;
        while(true){
            int divisor = numerator/2;
            int remainder = numerator%2;
            builder.append(remainder+"");
            numerator = divisor;
            if(divisor==1){
                builder.append("1");
                break;
            }else if(divisor==0){
                builder.append("0");
                break;
            }
        }
        return builder.reverse().toString();
  }
