設計一個學生類別

Question

設計一個學生類別(Student)。
類別具有姓名(name)、學號(id)、國文成績(chinese)、英文成績(english) 、數學成績(math)等欄位。
要設計有參數的建構子(包含姓名與學號)，
然後要可以計算國英數三科平均。
內含有3位學生成績，計算其平均，並印出。
PS.可讓使用者輸入成績。檔名Score2.java
謝謝~~

要讓使用者輸入？
可不可以幫我改一下^.^

Answer 1

public class Score2 { public static void main(String[] args) {  Student a = new Student("A", "0001");  Student b = new Student("B", "0131");  Student c = new Student("C", "2311");  a.setChineseGrade(100);  a.setEnglishGrade(91);  a.setMathGrade(72);  b.setChineseGrade(96);  b.setEnglishGrade(44);  b.setMathGrade(88);  c.setChineseGrade(81);  c.setEnglishGrade(99);  c.setMathGrade(93);    float cAvg = (a.getChineseGrade() + b.getChineseGrade() +    c.getChineseGrade()) / 3.0F;  float eAvg = (a.getEnglishGrade() + b.getEnglishGrade() +    c.getEnglishGrade()) / 3.0F;  float mAvg = (a.getMathGrade() + b.getMathGrade() +    c.getMathGrade()) / 3.0F;  System.out.println("國文總平均為: " + cAvg);  System.out.println("英文總平均為: " + eAvg);  System.out.println("數學總平均為: " + mAvg);    float avg1 = (a.getChineseGrade() + a.getEnglishGrade() +   a.getMathGrade()) / 3.0F;  float avg2 = (b.getChineseGrade() + b.getEnglishGrade() +   b.getMathGrade()) / 3.0F;  float avg3 = (c.getChineseGrade() + c.getEnglishGrade() +   c.getMathGrade()) / 3.0F;  System.out.println("學生" + a.getName() + "的平均成績為: " + avg1);  System.out.println("學生" + b.getName() + "的平均成績為: " + avg2);  System.out.println("學生" + b.getName() + "的平均成績為: " + avg3); }}class Student { String name, id; int cGrade, eGrade, mGrade;  Student(String n, String i) {  name = n;  id = i; }  public void setName(String n) {name = n;} public void setID(String i) {id = i;} public void setChineseGrade(int c) {cGrade = c;} public void setEnglishGrade(int e) {eGrade = e;} public void setMathGrade(int m) {mGrade = m;}  public String getName() {return name;} public String getID() {return id;} public int getChineseGrade() {return cGrade;} public int getEnglishGrade() {return eGrade;} public int getMathGrade() {return mGrade;}}
