标签:The   getname   uga   out   height   ***   sof   res   ==   

思路:定义两个类,一个scoreinformation类,一个scoremanagement类,scoreinformation类用于编写姓名,学号,以及各项成绩的输入函数,scoreinformation类有七个私有变量,和各个变量的get(),set()函数,scoremanagement类用于表现各项功能,包括学生信息的引入函数,学生信息的添加函数,学生信息的修改函数,学生成绩绩点的计算函数,以及退出系统的函数,在最后的主函数中,首先调用存储学生信息的函数,然后运用switch,case函数对各个函数进行调用,对应各项功能,进行函数的调用。

代码:scoreinformation类:

package xueshengxuejiguanlixitong;
public class scoreinformation {
 private String stunumber;
 private String name;
 private double mathematicsscore;
 private double englishscore;
 private double networkscore;
 private double databasescore;
 private double softwarescore;
 public void setstunumber(String stunumber)
 {
    this.stunumber = stunumber;
 }
 public String getstunumber()
 {
  return stunumber;
 }
 public void setname(String name)
 {
     this.name = name;
 }
 public String getname()
 {
      return name; 
 }
    public void setmathematicsscore(double mathematicsscore)
    {
     this.mathematicsscore = mathematicsscore;
    }
    public double getmathematicsscore()
    {
     return mathematicsscore;
    }
    public void setenglishscore(double englishscore)
    {
     this.englishscore = englishscore;
    }
    public double getenglishscore()
    {
     return englishscore;
    }
    public void setnetworkscore(double networkscore)
    {
     this.networkscore = networkscore;
    }
    public double getnetworkscore()
    {
     return networkscore;
    }
    public void setdatabasescore(double databasescore)
    {
     this.databasescore = databasescore;
    }
    public double getdatabasescore()
    {
     return databasescore;
    }
    public void setsoftwarescore(double softwarescore)
    {
     this.softwarescore = softwarescore;
    }
    public double getsoftwarescore()
    {
     return softwarescore;
    }
}
