Question

  public static void DecimalToBinary(int num){
              if(num == 0){         //当num=0时，循环结束
                     return;
              }else{
                     DecimalToBinary(num/2);   //调用递归方法
                     System.out.print (num%2);
              }
              }

Answer 1

public class TestData {
public static void main(String[] args) {
