題目說明

以下為Student類別的程式碼

class Student {

    // Field
    private String name = "Unknown";    // 名字
    private String id = "12156000";     // 學號
    private int totalCredits = 0;       // 累計學分數

    // Constructor
    public Student() {
    }
    public Student(String name, String id) {
        this.name = name;
        this.id = id;
    }

    // Method
    public void addCredits(int credits) {
        this.totalCredits += credits;
    }
    public void printId() {
        System.out.print(name + "'s student ID is " + id);
    }
    public int getCredits() {
        return totalCredits;
    }

}

使用上面定義的類別程式碼，在主程式區段寫出【執行學生資料建置】的程式碼

小提示

import java.util.Scanner;  

// 貼上Student類別的程式碼  

// 主程式區段  
public class MyProgram {

    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        // 宣告name、id

        // 請完成此區段程式碼
        // 必須使用Student類別
        // Student newStudent = new Student(name, id);

        // 累計學分，使用addCredits()

        // 輸出，使用printId()、getCredits()

    }

}

輸入

學生名字學生學號
已修習學分數(可有多項，當遇到0結束計算)

輸出

{name}'s student ID is {id}, total credits: {totalCredits}

測試資料1 輸入

zz 09156146
2 2 3 1 3 2 2 0 3 1

測試資料1 輸出

zz's student ID is 09156146, total credits: 15

累計學分：2+2+3+1+3+2+2=15

    public Student(String name, String id) {
        this.name = name;
        this.id = id;
    }

    // Method
    public void addCredits(int credits) {
        this.totalCredits += credits;
    }

    public void printId() {
        System.out.print(name + "'s student ID is " + id);
    }

    public int getCredits() {
        return totalCredits;

// 主程式區段

        Student newStudent = new Student(name, id); // 建立Student物件

        int credit = input.nextInt();
        while (credit != 0) {
            newStudent.addCredits(credit);          // 使用Student類別裡的Method，執行學分累加
            credit = input.nextInt();
        }
        input.close();

        newStudent.printId();                       // 使用Student類別裡的Method，印出學生資訊(名字、學號)
        System.out.print(", total credits: " + newStudent.getCredits());    // 使用Student類別裡的Method，取得累計學分
    }
