编写程序，从键盘上输入两个数，然后计算它们相除后得出的结果并输出

import java.util.Scanner;

public class for3_12 {
    public static void main(String[] args) {
        Scanner reader=new Scanner(System .in);
        double a=reader.nextDouble();
        double b=reader.nextDouble();
        double c=a/b;
        System.out.println(c);




    }
}
