Java控制台输入两个正整数，输出这两个 数的和/差/积/商

import java.util.Scanner;

public class JJCC {
    public static void main(String[] args) {
        Scanner s = new Scanner(System.in);
        System.out.println("请输入a：");
        float a = s.nextInt();

        System.out.println("请输入b：");
        float b = s.nextInt();

        System.out.println("和="+(a+b)+";差="+(a-b)+";积="+(a*b)+";商="+(a/b));
    }
}
