21. What is the purpose of the task in Ant?
Ans:- The task is used to create directories. It ensures that the specified directories exist before other tasks are executed.
22. How can I handle dependencies between targets in Ant?
Ans:- Ant allows you to specify dependencies between targets using the depends attribute. This ensures that certain targets are executed before others.
23. Explain the task in Ant.
Ans:- The task allows you to iterate over a set of values and execute a block of tasks for each value. It simplifies repetitive tasks in the build process.
24. How can I use Ant to generate documentation?
Ans:- Ant can be used with tools like Javadoc to generate documentation. Use the task to specify source files, output directory, and other Javadoc options.
25. What is the purpose of the task in Ant?
Ans:- The task is used to change the permissions of files or directories. It can set permissions for users, groups, and others.
26. How can I use Ant to compile non-Java source files?
Ans:- Ant supports various tasks for compiling non-Java source files, such as for Java, for annotation processing, for JavaCC, and others.
27. What is the Ant task used for?
Ans:- The task in Ant allows you to execute SQL statements against a database. It is useful for automating database-related tasks in the build process.
28. How do I create a zip file using Ant?
Ans:- Ant provides the task to create a zip file. Specify the zip file name, source files, and other options in the build file.
29. What is the purpose of the task in Ant?
Ans:- The task is used to create a tar archive. It allows you to specify the tar file name, source files, compression options, and other parameters.
30. How can I use Ant to deploy a web application?
Ans:- Ant can be used to deploy a web application by copying the necessary files to the deployment directory or by using specific deployment tasks provided by application servers.

Ans:- The build.xml file is the default name for the Ant build file. It contains the build instructions, targets, and tasks for a project.
36. How can I specify the order of execution for tasks in Ant?
Ans:- Ant executes tasks in the order they are specified in the build file. You can use target dependencies and the depends attribute to control the order explicitly.
37. How do I handle failures in Ant build scripts?
Ans:- Ant provides the task to explicitly fail the build if certain conditions are not met. You can use it to handle failures and stop the build process.
