学生成绩、学号、课程号的录入、显示(处理多个学生)

Question

package P97; import java.util.Scanner; class Staff{ private String staffNo;//学号 private String staffGrade;//成绩 private String staffclass;//课程号 public String getStaffNo(){ return staffNo; } public void setStaffNo(String staffNo){ this.staffNo=staffNo; } public String getStaffGrade(){ return staffGrade; } public void setStaffGrade(String staffGrade){ this.staffGrade=staffGrade; } public String getStaffclass(){ return staffclass; } public void setStaffclass(String staffclass){ this.staffclass=staffclass; } public void addBasicInfo(){ Scanner in=new Scanner(System.in); Scanner inStr=new Scanner(System.in); System.out.println("请输入学生基本信息："); System.out.println("学号："); staffNo=inStr.nextLine(); System.out.println("成绩："); staffGrade=inStr.nextLine(); System.out.print("课程号"); staffclass = inStr.nextLine(); } public void showBasicInfo () { System.out.println("学生信息："); System.out.println("学号\t成绩\t课程号"); System.out.println(staffNo + "\t" + staffGrade + "\t" +"\t" + staffclass ); } public void showBasicInfoWithoutTitle(){ System.out.println(staffNo + "\t" + staffGrade + "\t" + staffclass ); } } public class Demo61 { public static void main(String[] args) { Staff staff = new Staff(); staff.addBasicInfo(); staff.showBasicInfo(); } } 这个为什么只显示一个学生，如何让它显示多个学生？求具体代码
