java实现学生成绩录入系统

本文为大家分享了java实现学生成绩录入系统，供大家参考，具体内容如下

1.学生类，包括学生的姓名和各科成绩

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.对学生类进行设置，包括设置查找等

package score; 
 
public class ScoreZip { 
  Score[] S = new Score[5]; 
 
  public void setData(Score name, int index) {//添加成绩类到成绩数组中 
    S[index] = name; 
  } 
 
  public Score[] getData() { //返回学生数组 
    return S; 
  } 
 
  public Score SerchData(String name) { //查找学生各科成绩 
    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.学生成绩录入及学生成绩清单

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++) { //这里定义长度为五的学生成绩表 
      System.out.println("输入学生姓名:"); 
      String name = Sc.next(); 
      if (name.equals("n")) { 
 break; 
      } 
      System.out.println("英语分数:"); 
      double English = Sc.nextDouble(); 
      System.out.println("数学分数:"); 
      double Math = Sc.nextDouble(); 
      System.out.println("物理分数:"); 
      double Physical = Sc.nextDouble(); 
      System.out.println("化学分数:"); 
      double Chemical = Sc.nextDouble(); 
      System.out.println("生物分数:"); 
      double Biology = Sc.nextDouble(); 


      Score s = new Score(name, English,Math,Physical,Chemical,Biology); 
      Sr.setData(s, i); 
    } 
    System.out.println("=========================================" + 
 "学生成绩表======================================"); 
    System.out.println("姓名tt英语成绩tt数学成绩tt物理成绩tt化学成绩tt生物成绩"); 
    Score[] b = Sr.getData(); 
    for (Score S : b) { 
      if (S == null) { 
 break; 
      } 
      System.out.println(S.name + "tt" + S.EnglishGrade+"tt"+S.MathGrade 
   +"tt"+S.phyicalGrade+"tt"+S.chemicalGrade+"tt"+S.biologicalGrade); 
    } 
    System.out.println("是否查找学生成绩？ 是Y 否N"); 
    String flag = Sc.next(); 
    if(flag.equals("Y")){ 
    System.out.println("输入要查找的学生名:"); 
    String name = Sc.next(); 
    Score S = Sr.SerchData(name); 
    if (S == null) { 
      System.out.println("对不起，没有此学生名"); 
    } 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("要查找的学生为:" + name + "n数学成绩为:" + mg 
   + "n英语成绩为:" + eg+ "n物理成绩为:" + pg+ "n化学成绩为:" + cg 
   + "n生物成绩为:" + bg+ "n总成绩成绩为:" + submit); 
} 
    } 
  } 
}
