java编写学生成绩录入系统

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,
doubleMathGrade,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);
     }
}
}
}
