算是超簡單的問題了吧，Excel中用一個max()函式就能搞定的問題，我要寫這麼長程式碼才實現。

不過，寫程式碼有一種自由的感覺。在找到最大值的同時，可以告訴你最大值在哪裡。（相信Excel也有相應功能）

補記：

Excel中查詢一列資料中的最大值所在行，公式為：INDEX(A:A,MATCH(MAX(B:B),B:B))

程式碼如下：

//JHTP Exercise 4.21: Find the Largest Number
//by [email protected]
/* (Find the Largest Number) The process of finding the largest value is used frequently in computer
*applications. For example, a program that determines the winner of a sales contest would input
*the number of units sold by each salesperson. The salesperson who sells the most units wins the contest.
*Write a pseudocode program, then a Java application that inputs a series of 10 integers and determines
*and prints the largest integer. Your program should use at least the following three variables:
*a) counter: A counter to count to 10 (i.e., to keep track of how many numbers have been
*input and to determine when all 10 numbers have been processed).
*b) number: The integer most recently input by the user.
*c) largest: The largest number found so far.*/

import java.util.Scanner;

public class Test {

	public static void main(String[] args) {
		int counter=1;
		int largest=0;
		Scanner scanner=new Scanner(System.in);
		int number=0;
		int salesNo=1;
		int maxSalesNo=1;
		
		while (counter<=10){
			
			System.out.printf("請輸入銷售員No.%d的銷售額:",salesNo);
			number=scanner.nextInt();
			if(number>=largest)
			{largest=number;
			maxSalesNo=salesNo;
			}
			++counter;
			++salesNo;
		}
		System.out.printf("恭喜銷售員No.%d創造了最高銷售額:%d RMB",maxSalesNo,largest);
		}
}
 

執行結果：

請輸入銷售員No.1的銷售額:1
請輸入銷售員No.2的銷售額:2
請輸入銷售員No.3的銷售額:3
請輸入銷售員No.4的銷售額:9
請輸入銷售員No.5的銷售額:8
請輸入銷售員No.6的銷售額:7
請輸入銷售員No.7的銷售額:6
請輸入銷售員No.8的銷售額:5
請輸入銷售員No.9的銷售額:4
請輸入銷售員No.10的銷售額:2
恭喜銷售員No.4創造了最高銷售額:9 RMB
