Creating a Java Program in a Package from Command Line
Creating a Java Program in a Package from Command Line
In this tutorial, we will discuss how to compile and run a Java program that belongs to a package directly from the command line.
Here are the steps to create and execute a Java program in a package:
- Write a simple Java program and save it with the necessary package declaration. For example, let’s create a program called
HelloWorld
inside a package namedcom.example
: - Compile the program using the command:
- Run the compiled program using the command:
javac -d . HelloWorld.java
java com.example.HelloWorld
By following these steps, you can easily compile and run Java programs in packages from the command line.
If you encounter any issues, make sure that the package directory structure matches the package declaration in your Java program.
Java offers great flexibility in how you organize your code, and being able to compile and run programs from the command line is a valuable skill for any Java developer.
Practice creating and executing programs in packages to gain a better understanding of how packages work in Java.
