Java学习小练习

解题思路:

注意事项:将println方法改为printf方法，输出的类型为double，记得约9位小数

参考代码:

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

    Scanner scanner = new Scanner(System.in);

    while (scanner.hasNext()) {

        double a = scanner.nextDouble();

        double b = scanner.nextDouble();

        double c = a/b;

        System.out.printf("%.9f",c);

}

}

}
