How Can I Execute Batch Files from a Java Application?

Executing Batch Files in Java Applications

In Java applications, it is sometimes necessary to execute batch files to perform specific tasks. However, simply using Runtime.getRuntime().exec("build.bat") may not be sufficient due to the non-executable nature of batch files.

Solution: Calling the Batch File via a Command

To execute a batch file successfully, it is first necessary to call the application that will execute it. In Windows, this application is typically the command prompt (cmd). By using the following code, you can execute the batch file named build.bat:

Runtime.getRuntime().exec("cmd /c start \"\" build.bat");

Additional Information

• The start "" command opens a separate command window with a blank title, displaying any output from the batch file there.
• Alternatively, using cmd /c build.bat without the start "" command also works but may require reading the output from the sub-process in Java.
