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/t/t英语成绩/t/t数学成绩/t/t物理成绩/t/t化学成绩/t/t生物成绩");     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);        }     }   } }
