急！java的自动售货机找零程序

public class Change {

public static void main(String args[]){

Scanner sc = new Scanner(System.in);

System.out.print("The goods cost:");

int cost=sc.nextInt();

System.out.print("The customer paid:");

int paid=sc.nextInt();

change(cost,paid);

}

public static void change(int cost,int paid){

//unit of costpaid is dollar

int change=(paid-cost)*100;

int numOfTF=0;//number of 25 cents

int numOfT=0;//number of 10 cents

int numOfF=0;//number of 5 cents

if(change0)//payment is not enough

System.out.println("payment is not enough");

else{

numOfTF=(int)change/25;

numOfT=(int)(change-numOfTF*25)/10;

numOfF=(int)(change-numOfTF*25-numOfT*10)/5;

System.out.println("Change is: "+numOfTF+" 25 cents, "+numOfT+" 10 cents, "+numOfF+" 5 cents.");

Q2: JAVA 编程自动售货机系统

我说，这位同学，你们学校布置的题目你们怎么都来这索取答案来了。怎么不自己动手做做，而且你这里需要一个邮箱接收才行，你这样裸问让人很奇怪 ~
