牛客网在线编程题规范实例

牛客网华为笔试题通过案例，注意要引入包和输出：

import java.util.Scanner;public class Main {public static int getIntFromDouble(double a){return (int)(a+0.5);}public static void main(String[] args) {        Scanner in = new Scanner(System.in);        while(in.hasNextDouble()) {            double a = in.nextDouble();            System.out.println(getIntFromDouble(a));        }    }}

import java.util.Scanner;public class Main {    public static void main(String[] args) {        Scanner in = new Scanner(System.in);        while (in.hasNextInt()) {//注意while处理多个case            int a = in.nextInt();            int b = in.nextInt();            System.out.println(a + b);        }    }}
