用递归实现十进制转换成二进制

public class toBin {
public static void main(String[] args) {
StringBuffer result = new StringBuffer();
toBinary(100, result);
System.out.println(result);//1100100
}

public static void toBinary(int n, StringBuffer result) {
if (n / 2 != 0)
toBinary(n / 2, result);
result.append(n % 2);
}

}
