Don't waste your time on Swift unless you really want to develop Apple OS X or iOS software, OS X probably occupy 5% of PC market. Delphi 7/ VB6 are dead languages/markets, also don't waste your time.

If you are into data processing and database/inventory, MS Access is a good start, and do learn SQL/SQL query.

MS Access is a GUI/database combo.

Backend database/programming usually make more money then website/GUI designer (Javascript, html, css)and probably easier.

MS SQL Sever 2017 Developer is free.

MySQL is also free. All you need is Community Server and Workbench.

What are you trying to do?

If you are trying to learn how to program, then having a "Java stock program" won't be any more helpful than just about any java program.

Ultimately, you can learn some things from example programs, but my suggestion on learning how to program is to program. Programming is a skill you improve most by programming.

Pick a language, run through this

That will give you a better feel for how a language is to write then an example program will.

Here's an example of Java source code for a simple business application:

public class BusinessApplication {
private String companyName;
private int employeeCount;

public BusinessApplication(String name) {
companyName = name;
employeeCount = 0;
}

public void hireEmployee() {
employeeCount++;
}

public void fireEmployee() {
if (employeeCount > 0) {
employeeCount--;
}
}

public void printCompanyInfo() {
System.out.println("Company Name: " + companyName);
System.out.println("Employee Count: " + employeeCount);
}

public static void main(String[] args) {
BusinessApplication app = new BusinessApplication("ABC Company");
app.hireEmployee();
app.hireEmployee();
app.fireEmployee();
app.printCompanyInfo();
}
}

And here's an example of Java source code for a stock control system:





public class StockControlSystem {
private String productName;
private int stockQuantity;

public StockControlSystem(String name) {
productName = name;
stockQuantity = 0;
}

public void addToStock(int quantity) {
stockQuantity += quantity;
}

public void removeFromStock(int quantity) {
if (stockQuantity >= quantity) {
stockQuantity -= quantity;
} else {
System.out.println("Insufficient stock!");
}
}

public void printStockStatus() {
System.out.println("Product: " + productName);
System.out.println("Stock Quantity: " + stockQuantity);
}

public static void main(String[] args) {
StockControlSystem stockSystem = new StockControlSystem("Product A");
stockSystem.addToStock(100);
stockSystem.removeFromStock(50);
stockSystem.printStockStatus();
}
}

These are simplified examples to demonstrate basic functionality. In a real-world scenario, a business application or a stock control system would be much more complex and include additional features and functionality.
