Launch4j turns Java jars into native Windows executables, offering cross-platform capabilities for easier distribution of Java-based applications.
What's more, the wrapper provided by Launch4j enhances user experience through its custom process name, application icon, native pre-JRE splash screen, and Java download page that prompts users to download the appropriate JRE if it cannot be found. Launch4j also extracts the jar from the executable and allows for custom versions shown by Windows Explorer.
Other features of Launch4j include support for GUI and console apps, the ability to pass command line arguments, and the option to change the current directory to the executable location. You can also set JVM options like tweaking the garbage collection and set system properties. It's an excellent lightweight software with just 21 KB and may be used for commercial purposes.
Launch4j is a robust application that comes with a lot of features. There's support for 64-bit Windows, 64-bit JRE, and IBM JRE, along with the ability to set the initial process priority and allow running only a single instance of the application. Plus, dynamic initial and maximum heap sizes, redesigned error reporting with custom messages, and more detailed output from the runtime logging are all included.
Overall, Launch4j is a great tool that developers can use to wrap their Java applications in Windows native executables quickly. You can even wrap applications on Linux, making it a great cross-platform tool that's easy to use and provides an excellent user experience.
