III. Ui design Figure 1 login design
- The first thing is the login The user interface design will include a textfield for the user to enter their username and password, as well as a two-button login and register.
Figure 2 register design
- Secondly, the register UI design will include a textfield for the user to enter their username, password, and phone number , as well as a two-button register and cancel.
IV. Implementation
1.explain program structure
- I made a Java application with seven primary components: three jframes called login, register, and table, and four classes called my model, my model2, employee, and account model. Figure 4 program structure
- Then, member variables with methods are declared using the class I defined. Then I'll use them to populate the jframe i've created. I'll use that to develop functions for my software.
- Using the wireframe I made earlier as a guide, I developed my software interface and assigned variable names to each component (button,text fields, label, table, combo box, ...). Figure 5 demo structure
2.Explain classes
Account model class
- I imported the relevant libraries into this class in order to use the variables that I constructed. Figure 7 import libraries
- I designated the local variables with the relevant type(string,integer) as private to limit their use to this class and minimize duplication with variables used in other classes. Figure 8 local variables
- Then I declare variables-containing methods and use those methods to put data into the jframe.
- The first is the manner of startup. This function is used to initialize the objects I defined before. This allows me to initialize values for attributes included within them as well as call other coreresponding methods to initialize the logic contained within the objects.
Figure 9 object
- I then use java's encapsulation using getter and setter methods to specify accessibility for the private attributes I created before and allow them to be seen and edited. Figure 10 getter setter
Mymodel , mymodel2 class Figure 12 mymodel
- First, I imported the necessary libraries into this class so that I could utilize the variables that I created. Next, I made the necessary type's local variables (string, integer) private in order to limit their use to this class and avoid duplication with variables used in other classes. then i created a public class called My Model, implementing ComboBoxModel to store information about my employees' hobbies. Then I make a list called hobbies to store the information. Finally, I created an object to store that information for each of the hobbies as an option in the comboBox.
Figure 13 mymodel 2
variables-containing methods and utilize those methods to populate the jframe with data. The first is the starting method. This method is used to initialize the previously declared objects. This enables me to set values for attributes included within them as well as call other corresponding methods to set the logic contained within the objects. I next utilize Java's encapsulation, which includes getter and setter methods, to define access to the private properties I generated before and allow them to be seen and updated.
3. Explain important algorithms
- This is the "Login button" function. When a user enters their username and password into the text boxes, the application saves them in variables. If the text fields were left blank, the application would display a message window and prompt the user to fill up all text fields. If the username and password given by the user match the accounts in the "accounts list," the user will be able to access the main form. Figure 15 login
- This is the function for “Register button”. If the user press register button, the application will open register form and close the login form. Figure 16 register
- This function is used to check if accounts empty new arraylist will be created. A new data will be added to “accounts” and write in file. Figure 17 check
