問題：將10個不同的標記讀入我的標記變量。 FOR循環

Question

import java.util.*; 

public class loops 

{ 

public static void main (String []args) 

    { 

     Scanner input = new Scanner (System.in).useDelimiter("\n"); 

     for (int i = 0; i <= 9; i++) 
     { 
        System.out.print("Enter your mark: "); 
        int marks = input.nextInt(); 
     } 

     int marks = + input.nextInt(); 
     int totalmarks = marks/10; 

     System.out.println("The class average was:"+ totalmarks + "."); 
    } 
} 

Answer 1

這個問題沒有明確的問題，但根據我的解釋，問題是添加所有輸入標記並給出平均值，所以聲明一個初始值爲0的和變量，並添加所有標記作爲輸入並取平均值。

import java.util.*; 

public class loops 

{ 

public static void main (String []args) 

{ 

    Scanner input = new Scanner (System.in).useDelimiter("\n"); 
    int sum=0; 
    for (int i = 0; i <= 9; i++) 
    { 
       System.out.print("Enter your mark: "); 
       int marks = input.nextInt(); 
       sum=sum+marks; 
    } 


    int totalmarks = sum/10; 

    System.out.println("The class average was:"+ totalmarks + "."); 
} 
}
