java實現學產生績錄入系統，java學產生績錄入

本文為大家分享了java實現學產生績錄入系統，供大家參考，具體內容如下

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，包括設定尋找等

package score;  public class ScoreZip {   Score[] S = new Score[5];    public void setData(Score name, int index) {//添加成績類到成績數組中     S[index] = name;   }    public Score[] getData() { //返回學生數組     return S;   }    public Score SerchData(String name) { //尋找學生各科成績     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.學產生績錄入及學產生績清單

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產生績表       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("=========================================" +         "學產生績表======================================");     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("是否尋找學產生績？ 是Y 否N");     String flag = Sc.next();     if(flag.equals("Y")){     System.out.println("輸入要尋找的學生名:");     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("要尋找的學生為:" + 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);        }     }   } }
