POJ 1004 Financial Management

原来前面的几道都是简单题，好吧，练下手，就当熟悉下吧。

此题求12个月的平均值，代码如下：

 

import java.util.Scanner;

public class Main {
	public void run() throws Exception {
		Scanner scan = new Scanner(System.in);
		double sum = 0.0d;
		for (int i = 0; i < 12; i++) {
			double input = scan.nextDouble();
			sum += input;
		}

		System.out.println("$" + String.format("%.02f", (sum / 12)));
	}

	public static void main(String[] args) {
		Main m = new Main();
		try {
			m.run();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
