How to create a Jar File your programmer

The errors you’re encountering are because the javac command is not able to find the DBConfig class during the compilation of the DataBase class. You need to ensure that the DBConfig class is compiled first and that both classes are available in the classpath during the compilation process.

Here is how you can properly compile your classes:

1. Ensure Directory Structure: Make sure your directory structure matches the package names: ```canvas jdbc-connection └── src └── com └── gagan ├── config │ └── DBConfig.java └── database └── DataBase.java

2. **Compile Both Classes:** Compile the `DBConfig` class first and then compile the `DataBase` class by including the output directory in the classpath.
```bash
cd W:\Programmer\Project++\jdbc-connection\src
javac -d out com/gagan/config/DBConfig.java
javac -d out -cp out com/gagan/database/DataBase.java

1. Package the Compiled Classes into a JAR: Create a JAR file containing both classes. ```bash cd out jar cvf database-connection.jar com/gagan/config/DBConfig.class com/gagan/database/DataBase.class

Here's a simplified script to automate the process:
```bash
cd W:\Programmer\Project++\jdbc-connection\src

# Compile DBConfig.java
javac -d out com/gagan/config/DBConfig.java

# Compile DataBase.java, including the 'out' directory in the classpath to find DBConfig.class
javac -d out -cp out com/gagan/database/DataBase.java

# Change to the 'out' directory
cd out

# Create the JAR file
jar cvf database-connection.jar com/gagan/config/DBConfig.class com/gagan/database/DataBase.class

Make sure to adjust the path separators (/ for Unix-like systems, \ for Windows) accordingly.

This should fix the compilation issues and create the JAR file successfully.
