CRUD Operations In Java With Source Code

CRUD Operations In Java With Source Code

The CRUD Operations In Java is developed using JAVAMySQL Connector and MySQL Database, In this Basic CRUD Operations In Java are equivalent to the INSERT, SELECT, UPDATE and DELETE statements in MySQL language.

A CRUD Operation Using JDBC In Java Program is going to help you learning how to do basic database operations (CRUD – Create, Retrieve, Update and Delete) using JDBC (Java Database Connectivity) API. This CRUD Operations In Java Using NetBeans is good for the beginners who wants to learn java programming language.

This Database CRUD Operations In Java also includes a downloadable CRUD In Java Source Code for free, just find the downloadable source code below and click to start downloading.

To start creating a CRUD Operations In Java, makes sure that you have NeatBeans IDE installed in your computer.

Steps on how to create a CRUD Operations In Java With Source Code

CRUD Operations In Java With Source Code

  • Step 1: Create project.

    First, open file and then click “project” to create.
    CRUD create project

  • Step 2: Create project name.

    Second, name your project.
    CRUD project name

  • Step 3: Create JFrame.

    Third, create “JFrame” form.
    CRUD jframe

  • Step 4: Create JFrame name.

    Fourth, name your JFrame form.
    CRUD jframe form

  • Step 5: Project Design.

    Fifth, The actual design of the project.
    CRUD output

  • Step 6: Actual Coding.

    you are free to copy the code given below and paste it into your java swing design.

The Code Given Below Is For The CRUD Operations In Java Connection To MySQL

try{
Class.forName("com.mysql.jdbc.Driver");
 String conURL = "jdbc:mysql://localhost/user1?"
         + "user=root&password=";
 java.sql.Connection con = DriverManager.getConnection(conURL);
    
        }catch(SQLException x){
   x.printStackTrace();
}       catch (ClassNotFoundException ex) {
            Logger.getLogger(MainFrame.class.getName()).log(Level.SEVERE, null, ex);
        }

In this module which is the connection under java into mysql database.

                String sql = "select * from student where id_number='" + id + "'";
                st = con.createStatement();
                ResultSet rs = st.executeQuery(sql);
                if (!rs.first()) {

                    DefaultTableModel model = (DefaultTableModel) tblStudents.getModel();
                    Object[] row = new Object[4];
                    row[0] = fname;
                    row[1] = lname;
                    row[2] = id;
                    model.addRow(row);
                } else {
                    alert("Please provide a different id number", "Similar id found");
                }

                clear();
            } catch (SQLException | ClassNotFoundException ex) {
                Logger.getLogger(Crud.class.getName()).log(Level.SEVERE, null, ex);
            } finally {
                try {
                    con.close();
                    st.close();
                } catch (SQLException ex) {
                    Logger.getLogger(Crud.class.getName()).log(Level.SEVERE, null, ex);
                }
            }
        } //        else if (!id.matches("^[0-9]{8}$")) {
        //            alert("please provide a valid id number", "Wrong id");
        //        } 
        else {
            alert("please fill in all the details");
        }
    }

In this module which is the adding of data into mysql database.

The Code Given Below Is For The Update Module

String fname = txtFname.getText().trim();
        String lname = txtLname.getText().trim();
        String id = txtId.getText().trim();
        if (!fname.isEmpty() && !lname.isEmpty() && !id.isEmpty()) {

                if (rs.first()) {
                    update(fname, lname, id);
                    DefaultTableModel model = (DefaultTableModel) tblStudents.getModel();
                    model.setRowCount(0);                   
                    fetch();
                    alert("Update was successful");
                    
                } else {
                    alert("There is no such student", "Update error");
                    clear();
                }

            } catch (ClassNotFoundException | SQLException ex) {
                Logger.getLogger(Crud.class.getName()).log(Level.SEVERE, null, ex);
            }
        } else {
            alert("There is nothing to update :(","No row selected");
        }
    }

In this module which is the update module of data from mysql database.

The Code Given Below Is For The Delete Module

int i = tblStudents.getSelectedRow();
        if (i >= 0) {
            int option = JOptionPane.showConfirmDialog(rootPane,
                    "Are you sure you want to Delete?", "Delete confirmation", JOptionPane.YES_NO_OPTION);
            if (option == 0) {
                TableModel model = tblStudents.getModel();

                String id = model.getValueAt(i, 2).toString();
                if (tblStudents.getSelectedRows().length == 1) {
                    delete(id);
                    DefaultTableModel model1 = (DefaultTableModel) tblStudents.getModel();
                    model1.setRowCount(0);
                    fetch();
                    clear();
                }
            }
        } else {
            alert("Please select a row to delete");
        }

In this module which is the delete module of the system from mysql database.
