College Administration project source code

College Administration project


: Insert delete and edit student details

Java Example for student manipulations, insertion, deletion, updates and search to an arraylist

The program explains how to use java arraylist,java bean class, java enumerator and how to create a model class for a project

Main class



import com.nij.ca.view.InputClass;


public class Main {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
      
        InputClass inputClass_ins = new InputClass();
        inputClass_ins.getInput();

    }

}

Student bean : StudentBean.java



package com.nij.ca.bean;

public class StudentBean {
   
    private String studentName = null;
    private int studentRegNo =0;
   
   
   
    public String getStudentName() {
        return studentName;
    }
    public void setStudentName(String studentName) {
        this.studentName = studentName;
    }
    public int getStudentRegNo() {
        return studentRegNo;
    }
    public void setStudentRegNo(int studentRegNo) {
        this.studentRegNo = studentRegNo;
    }
   

}

ChoiceEnum.java


package com.nij.ca.Enum;

public enum ChoiceEnum {
   
    INSERT,VIEW,EDIT,SEARCH,DELETE,EXIT

}

Inputclass.java
