本文介绍了一个用于管理学生基本信息及成绩的学生信息类的设计与实现。该类能够存储学生的姓名及三门课程的成绩，并提供计算总分、平均分、最高分及最低分的方法。通过实例化该类并输入具体信息，可以方便地查看学生的各项成绩指标。

import java.util.*; class StuInfo{ private String name; private int comScore; private int mathScore; private int engScore; public StuInfo(){}; public StuInfo(String name, int comScore, int mathScore, int engScore){ this.setName(name); this.setComScore(comScore); this.setMathScore(mathScore); this.setEngScore(engScore); } public void setName(String name){ this.name = name; } public void setComScore(int comScore){ if(comScore >=0 && comScore <=120){ this.comScore = comScore; } } public void setMathScore(int mathScore){ if(mathScore >=0 && mathScore <=120){ this.mathScore = mathScore; } } public void setEngScore(int engScore){ if(engScore >=0 && engScore <=120){ this.engScore = engScore; } } public String getName(){ return name; } public int getComScore(){ return comScore; } public int getMathScore(){ return mathScore; } public int getEngScore(){ return engScore; } public int sum(){ //总分 return comScore + mathScore + engScore; } public int avg(){ //平均分 return sum() / 3; } public int max(){ //最高分 int max = comScore > mathScore ? comScore:mathScore; max = max > engScore ? max:engScore; return max; } public int min(){ //最低分 int min = comScore < mathScore ? comScore:mathScore; min = min < engScore ? min:engScore; return min; } public String getInfo(){ //取出信息 return "学生信息:/n" + "/t姓名：" + this.getName() + "/n" + "/t计算机成绩：" + this.getComScore() + "/n" + "/t数学成绩：" + this.getMathScore() + "/n" + "/t英语成绩：" + this.getEngScore() + "/n" + "/t最高分：" + this.max() + "/n" + "/t最低分：" + this.min() + "/n" + "/t总分：" + this. sum() + "/n" + "/t平均分：" + this.avg(); } } //下面是主方法 public class Test{ public static void main(String [] args){ Scanner input = new Scanner(System.in); System.out.print("请输入您的姓名:"); String name = input.next(); System.out.print("请输入您的计算机成绩:"); int comScore = input.nextInt(); System.out.print("请输入您的数学成绩:"); int mathScore = input.nextInt(); System.out.print("请输入您的英语成绩:"); int engScore = input.nextInt(); StuInfo stu = new StuInfo(name,comScore,mathScore,engScore); System.out.println(stu.getInfo()); } }
