Dear Programmers please help me with this task;
I need a program written in any language including java, c++, javascript etc to show \'\' best chain solution \'\' with a simple user interface from decision making tree for example
here i built a tree from google search with it\'s priority tags such as 0.9 , 0.8 , 0.7
what i need ?
Step 1) Progam should have basic user interface with all of leaf and internal nodes to be selected by user in a kind of list and a button with title \'\' Please select for the solution \'\' >> registrar, websites, lookup, login, ultimate team, not working, format, to pdf online, conventer, registration, definition, fifa 17, development, ideas etc..
Step 2) User selects one / or more of those leaf or internal nodes and program shows us in user interface results according to sum of priority tags
For example user selected two leaf nodes registrar and login , then program shows us results like;
Best chain solutions;
1) Web_address_registration_registrar
2) Web_app_fifa_17_login
and this order of results depends on sum of priority tags 1) 0.9 + 0.9 + 0.9 = 2.7 2) 0.8 + 0.9 + 0.9 = 2.6
Step 3) User interface should have additional button like \'\' Try again \'\' or \'\' Go back \'\' for selecting and getting results again.
All i need source codes and screenshot of running program if possible. I don\'t have time problem for the solution. Just answer whenever you complete this program please. You can use my tree for the program. No matter. You do not need to create a new tree.
address 0.9 0.8 registration definition 0.9 0.8 registrar websites Web 0.9 0.7 0.8 0.9 0.9 archive 0.7 app 0.7 0.7 0.8 0.8 lookup fifa 17 way back instagram development ideas file 0.9 0.7 0.8 ultimate format to pdf online conventer not working lookup teamSolution
Below is the sample java program along with the Database connectivity for the login page.
Fill the form fields i.e. username and password and click on SignUp button.After fill up all the fields when you click on SignUp button JOptionPane message window will be display.
To create sign up page along with database connectivity in java where we have created a new user sign up page and stored its record into database with the help of SQL statements and also viewed the table records with the help of respective SQL queries.

You can check into MySQL database
Example of SQL Query:select * from `demo`.`loginaccount`
