1.學生類  包括學生的姓名和各科成績

public class Score {
	public String name;
    public double EnglishGrade,	MathGrade,phyicalGrade,
    chemicalGrade,biologicalGrade;
	Score() {

	}

	public Score(String name,double EnglishGrade,
			double	MathGrade,double phyicalGrade,
			double chemicalGrade,double biologicalGrade){
		this.name = name;
		this.EnglishGrade = EnglishGrade;
		this.MathGrade = MathGrade; 
		this.phyicalGrade = phyicalGrade;
		this.chemicalGrade = chemicalGrade;
		this.biologicalGrade = biologicalGrade;
		
	}

}
 

2.對學生類進行設定 包括設定查詢等

package score;

public class ScoreZip {
	Score[] S = new Score[5];

	public void setData(Score name, int index) {//新增成績類到成績陣列中
		S[index] = name;
	}

	public Score[] getData() { //返回學生陣列
		return S;
	}

	public Score SerchData(String name) {  //查詢學生各科成績
		for (int index = 0; index < S.length; index++) {
			if (name !=null && S[index] != null )
				if (S[index].name.equals(name)){
					return S[index];
				}
		 }
		return null;
	}
}
 

3.學生成績錄入及學生成績清單

package score;

import java.util.Scanner;


public class ScoreZip2 {
	public static void main(String[] arr) {
		Scanner Sc = new Scanner(System.in);
		ScoreZip Sr = new ScoreZip();
		for (int i = 0; i < 5; i++) { //這裡定義長度為五的學生成績表
			System.out.println("輸入學生姓名:");
			String name = Sc.next();
			if (name.equals("n")) {
				break;
			}
			System.out.println("英語分數:");
			double English = Sc.nextDouble();
			System.out.println("數學分數:");
			double Math = Sc.nextDouble();
			System.out.println("物理分數:");
			double Physical = Sc.nextDouble();
			System.out.println("化學分數:");
			double Chemical = Sc.nextDouble();
			System.out.println("生物分數:");
			double Biology = Sc.nextDouble();
			
			
			Score s = new Score(name, English,Math,Physical,Chemical,Biology);
			Sr.setData(s, i);
		}
		System.out.println("=========================================" +
				"學生成績表======================================");
		System.out.println("姓名\t\t英語成績\t\t數學成績\t\t物理成績\t\t化學成績\t\t生物成績");
		Score[] b = Sr.getData();
		for (Score S : b) {
			if (S == null) {
				break;
			}
			System.out.println(S.name + "\t\t" + S.EnglishGrade+"\t\t"+S.MathGrade
					+"\t\t"+S.phyicalGrade+"\t\t"+S.chemicalGrade+"\t\t"+S.biologicalGrade);
		}
		System.out.println("是否查詢學生成績？ 是Y 否N");
		String flag = Sc.next();
		if(flag.equals("Y")){
		System.out.println("輸入要查詢的學生名:");
		String name = Sc.next();
		Score S = Sr.SerchData(name);
		if (S == null) {
			System.out.println("對不起，沒有此學生名");
		} else {
			double mg = S.MathGrade;
			double eg = S.EnglishGrade;
			double pg = S.phyicalGrade;
			double cg= S.chemicalGrade;
			double bg = S.biologicalGrade;
			double submit = mg+eg+pg+cg+bg;
			System.out.println("要查詢的學生為:" + name + "\n數學成績為:" + mg
					+ "\n英語成績為:" + eg+ "\n物理成績為:" + pg+ "\n化學成績為:" + cg
					+ "\n生物成績為:" + bg+ "\n總成績成績為:" + submit);
		     }
		}
	}
}
