這篇文章主要為大家詳細(xì)介紹了java實(shí)現(xiàn)學(xué)生成績(jī)錄入系統(tǒng)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文為大家分享了java實(shí)現(xiàn)學(xué)生成績(jī)錄入系統(tǒng)，供大家參考，具體內(nèi)容如下

1.學(xué)生類，包括學(xué)生的姓名和各科成績(jī)

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(duì)學(xué)生類進(jìn)行設(shè)置，包括設(shè)置查找等

package score; 
 
public class ScoreZip { 
  Score[] S = new Score[5]; 
 
  public void setData(Score name, int index) {//添加成績(jī)類到成績(jī)數(shù)組中 
    S[index] = name; 
  } 
 
  public Score[] getData() { //返回學(xué)生數(shù)組 
    return S; 
  } 
 
  public Score SerchData(String name) { //查找學(xué)生各科成績(jī) 
    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(xué)生成績(jī)錄入及學(xué)生成績(jī)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++) { //這里定義長(zhǎng)度為五的學(xué)生成績(jī)表 
      System.out.println("輸入學(xué)生姓名:"); 
      String name = Sc.next(); 
      if (name.equals("n")) { 
        break; 
      } 
      System.out.println("英語(yǔ)分?jǐn)?shù):"); 
      double English = Sc.nextDouble(); 
      System.out.println("數(shù)學(xué)分?jǐn)?shù):"); 
      double Math = Sc.nextDouble(); 
      System.out.println("物理分?jǐn)?shù):"); 
      double Physical = Sc.nextDouble(); 
      System.out.println("化學(xué)分?jǐn)?shù):"); 
      double Chemical = Sc.nextDouble(); 
      System.out.println("生物分?jǐn)?shù):"); 
      double Biology = Sc.nextDouble(); 
       
       
      Score s = new Score(name, English,Math,Physical,Chemical,Biology); 
      Sr.setData(s, i); 
    } 
    System.out.println("=========================================" + 
        "學(xué)生成績(jī)表======================================"); 
    System.out.println("姓名\t\t英語(yǔ)成績(jī)\t\t數(shù)學(xué)成績(jī)\t\t物理成績(jī)\t\t化學(xué)成績(jī)\t\t生物成績(jī)"); 
    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("是否查找學(xué)生成績(jī)？ 是Y 否N"); 
    String flag = Sc.next(); 
    if(flag.equals("Y")){ 
    System.out.println("輸入要查找的學(xué)生名:"); 
    String name = Sc.next(); 
    Score S = Sr.SerchData(name); 
    if (S == null) { 
      System.out.println("對(duì)不起，沒(méi)有此學(xué)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("要查找的學(xué)生為:" + name + "\n數(shù)學(xué)成績(jī)?yōu)?" + mg 
          + "\n英語(yǔ)成績(jī)?yōu)?" + eg+ "\n物理成績(jī)?yōu)?" + pg+ "\n化學(xué)成績(jī)?yōu)?" + cg 
          + "\n生物成績(jī)?yōu)?" + bg+ "\n總成績(jī)成績(jī)?yōu)?" + submit); 
       } 
    } 
  } 
}
