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);

}

}

}

}
