I am new in java. I am trying convert simple java app with terminal output to a app with a GUI or UI. I have seen small java applications with little window , like calculator or currency converter.

This is the program I am trying to convert to a GUI app https://github.com/Abhinav-26/Employee-Management-System/blob/master/EmployManagementSystem.java

I have tried to run this app. I am getting the out put in a terminal. (image 1)terminal output

I need a UI to this simple app , like image 2 - example of ui

I am expecting to get a simple java app with UI , like in picture 2. Is there a way to edit existing app ? What should I google / lookup ?

Look into java swing. You can create a JWindow and JFrame with other elements in it like JButton and JTextInput.

There are many tutorials on how to build a calculator by using JavaFX.

I'll list just a few:

• Simple JavaFX Calculator at CodeReview
• Simple basic Calculator Javafx at stackoverflow
• JavaFX Software Tutorial: Calculator (MVC) on YouTube
• Making Calculator in JavaFX (with Source Code)
• JavaFX implementation calculator at Very Interesting Programming

You can easily find more. If you want to build a standalone application, building a calculator is a better starting point than building some employee management system.

What do I mean by standalone? Unlike a standalone calculator the technical architecture of an employee management system requires some sort of storage. The typical storage-solution would be a database. Then you need some non-UI code to access this storage, I'll call this the server. And finally there will be some UI, I'll call this the client. So the complete application has three tiers: database, server and client. The calculator example has only one tier, everything is included in a single app.

So if you are looking for a tutorial on an employee managment system, you might want to search for tutorials that use a multi-tier-architecture. One common architecture will be a server build with Spring Boot. And there you are – you can easily find tutorials on building an employee managment system with Spring Boot.

Here are two of them but there are many more:

• Spring Boot Tutorial - Build Employee Management Project from Scratch using Spring Boot Spring Security Thymeleaf and MySQL Database
• Create and View Employee Using JPA, Springboot and Thymeleaf

The downside is: You will not be able to use existing code.

So now you have two options:

1. Learn some Java UI-Framework such as JavaFX or the older Java Swing.
2. Learn how to build a more complex Java application that has at least some sort of client and some sort of server. Spring Boot is a good starting point for this.
