Question

Java写一个类用于演示输入一个5位数,计算出各位数的总和,并倒序输出。

Answer 1

/**
* @param args
*/
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("请输入5次数字,每次以回车结束.");
try{
int num1 = sc.nextInt();
int num2 = sc.nextInt();
int num3 = sc.nextInt();
int num4 = sc.nextInt();
int num5 = sc.nextInt();
List<Integer> list = new ArrayList<Integer>();
list.add(num1);
list.add(num2);
list.add(num3);
list.add(num4);
list.add(num5);
int sum = num1+num2+num3+num4+num5;
System.out.println("总和"+sum);
Collections.reverse(list);
for(Integer i : list){
System.out.println(i);
}
} catch(Exception e){
System.out.println("输入错误");
}

}
