Java小練習(1)

1. 請設計一程式分別可以接受使用者輸入「國文、英文、數學」分數後， 將總分及平均顯示出來。 //######### source code starts from here #################

import java.util.Scanner;
//因為需要接收使用者輸入，因此因此import  java.util.Scanner這個套件。

public class Lab{
   public static void main(String args[]){
       Scanner keyin = new Scanner(System.in);

       System.out.println("score of chinese");
       float chi = keyin.nextFloat();

       System.out.println("score of English");
       float eng = keyin.nextFloat();

       System.out.println("score of Math");
       float math = keyin.nextFloat();

       float sum = (float)chi+eng+math;
       float avg = sum/3.0F;
       System.out.println("Yor score is "+sum+" and the avg is "+avg);
       System.out.print("this semester is :");
       System.out.println(avg>=60? "Passed!" : "Failed!");
       //二擇一的情況可以不需要用到if/else敘述
   }
}
