This article will explain in detail how to implement the student information management system in java. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

The details are as follows

/ * Student information management system to implement student information: * add int [] a=new int [9] * Delete * find * change * / import java.util.Scanner;// import java input stream import java.lang.*; import java.io.*; class Student {private static Student [] s=new Student [2]; int information 0; private String name; private int num; private String classAge; public void judge () throws IOException {int i; char ch; String str Scanner In=new Scanner (System.in); if (incorrectly loaded 0) {System.out.print ("you haven't enrolled any students yet, whether or not you have enrolled (YUnip N):"); str=In.next (); ch=str.charAt (0); while (incorrectly typed, please re-enter:) Str=In.next (); ch=str.charAt (0);} if (ch=='Y' | | ch=='y') {this.add ();} if (ch=='N' | | ch=='n') {this.menu ();} public void menu () throws IOException// defines the menu function {int _ this.menu () throws IOException// / defines the switch statement variable Scanner in=new Scanner (System.in) / / instantiate the input stream object System.out.println ("* Student Information Management system function Table *"); System.out.println ("* 1.
