從鍵盤讀取三個數值並求平均值

import java.util.Scanner;
public class ComputerAverage{
	public static void main(String[ ]args){
		Scanner input =new Scanner (System.in);
		System.out.print("Enter three numbers:");
		double number1=input.nextDouble();
		double number2=input.nextDouble();
		double number3=input.nextDouble();
		double average=(number1+number2+number3)/3;
		System.out.println("The average of"+number1+" "+
		number2+" "+number3+" is "+average);
	}
}

敲出一個代碼並不代表你理解它了；敲出一個代碼並不是最大的成就；敲一個代碼的時候不應該帶着單純是完成任務的心態。我認爲我們應該試着去理解它的語法，明白爲什麼。
