1、Java学生信息管理系统（面向对象）一：效果如下：二：具体实现代码如下：Student类Student.javapublicclassStudent{privateintid;privateStringname;privateintage;privateintjava;privateintcsharp;privateinthtml;privateintsql;privateintsum;privateintavg;publicintgetId(){returnid;}publicvoidsetId(intid){this.id=id;}publicSt

2、ringgetName(){returnname;}publicvoidsetName(Stringname){this.name=name;}publicintgetAge(){returnage;}publicvoidsetAge(intage){this.age=age;}publicintgetJava(){returnjava;}publicvoidsetJava(intjava){this.java=java;}publicintgetCsharp(){returncsharp;}publicvoidsetCsharp(intcsharp)

3、{this.csharp=csharp;}publicintgetHtml(){returnhtml;}publicvoidsetHtml(inthtml){this.html=html;}publicintgetSql(){returnsql;}publicvoidsetSql(intsql){this.sql=sql;}publicintgetSum(){returnsum;}publicvoidsetSum(){this.sum=this.java+this.csharp+this.html+this.sql;}publicintgetAvg()

4、{returnavg;}publicvoidsetAvg(){this.avg=this.sum/4;}publicStringtoString(){Stringmsg="t"+this.id+"t"+this.name+"t"+this.age+"t"+this.java+"t"+this.csharp+"t"+this.html+"t"+this.sql+"t"+this.sum+"t"+this.avg;returnmsg;}}学生信息管理类StudentAdmin.javaimportjava.util.Scanner;pub

5、licclassStudentAdmin{Stringmsg="t编号t姓名t年龄tjavatcsharpthtmltsqlt总分t平均分";//打印现有学生publicvoidprint(Student[]stu){System.out.println(msg);for(inti=0;i

6、udentstudent=newStudent();student.setName(name);student.setAge(age);inti=this.getIndex(stu);if(i==9999){System.out.println("数组已经容纳最大量，不能再接受");}else{student.setId(i);}stu[i]=student;}//获取编号publicintgetIndex(Student[]stu){for(inti=0;i

7、urn9999;}//根据学生编号查找学生publicvoidselectStudent(intid,Student[]stu){System.out.println(msg);for(inti=0;i

8、eanexits(intid,Studentstu){if(stu!=null){if(stu
