+====Let LLM Help with Nashorn Javascript====
+If you ask ChatGTP to generate some sample code if you specifically indicate that you'd like Nashorn compatibility. For example, the prompt "Please generate Nashorn compatible javascript code to find and delete the oldest log file with extension ".log" from a specific directory" would result in this:
+<code javascript>
+// Import Java classes for file operations
+var Files = Java.type('java.nio.file.Files');
+var Paths = Java.type('java.nio.file.Paths');
+var FileVisitOption = Java.type('java.nio.file.FileVisitOption');
+var StandardOpenOption = Java.type('java.nio.file.StandardOpenOption');
+var FileVisitResult = Java.type('java.nio.file.FileVisitResult');
+var File = Java.type('java.io.File');
+// Specify the directory path
+var directoryPath = Paths.get("/path/to/your/directory");
+// Function to delete the oldest log file
+function deleteOldestLogFile(directoryPath) {
+    // Get a list of all log files in the directory
+    var logFiles = Files.walk(directoryPath, 1, FileVisitOption.FOLLOW_LINKS)
+        .filter(function (path) {
+            return Files.isRegularFile(path) && path.toString().endsWith(".log");
+        })
+        .map(function (path) {
+            return {
+                path: path,
+                creationTime: Files.readAttributes(path, 'creationTime').creationTime().toMillis()
+            };
+        })
+        .sorted(function (file1, file2) {
+            return Long.compare(file1.creationTime, file2.creationTime);
+        })
+        .toArray();
+    if (logFiles.length === 0) {
+        print('No log files found in the directory.');
+        return;
+    }
+    // Get the oldest log file
+    var oldestLogFile = logFiles[0];
+    // Delete the oldest log file
+    try {
+        Files.deleteIfExists(oldestLogFile.path);
+        print('Deleted oldest log file:', oldestLogFile.path);
+    } catch (e) {
+        print('Error deleting file:', e.message);
+    }
+}
+// Call the function to delete the oldest log file
+deleteOldestLogFile(directoryPath);
