以下是题1的代码
public class Test {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int input = scanner.nextInt();
boolean flag = false;
int temp = 0;
while(input%10>0){
temp += input%10;
input = input/10;
}
temp = temp + input;
if(temp%9==0){
flag = true;
}
System.out.println(flag?"能整除":"不能整除");
}
}
以下是题2的代码
public class Test1 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入路程");
int km = scanner.nextInt();
double price = new Test1().getprice(km);
System.out.println("单价/吨:"+price);
System.out.println("请输入重量(T)");
int h = scanner.nextInt();
System.out.println("价格为:"+(price*h));
}
public double getprice(int km){
double price = 0;
if(km=100&&km=300&&km=500&&km
