Answer 1

 
修改下代码就可以了。
while(small >0&&i >=0) 
          { 
               
                 if(small%10!=0) 
                 { 
                 str1=data[small%10]; 
                  str2=String.valueOf(money_small); 
                  strSmall=""+str1+str2+strSmall; 
                 } 
               
                  small=small/10; 
                  i=i-1; 
          }
