How do I write a sailpoint beanshell java script to read a latest file

Hi srikanth,

To read a file with the latest timestamp and a specific prefix in Java using the SailPoint BeanShell, you can follow these steps:

import java.io.File;
import java.util.Arrays;
import java.util.Comparator;
import java.util.regex.Pattern;

2. define directory

String directoryPath = "/path/to/files";

3. define prefix

String filePrefix = "SampleFile";

4, create a file object in directory'

File directory = new File(directoryPath);

5.Create a File[] array to store all the files

File[] files = directory.listFiles();

6.Use a custom Comparator  and Define a regular expression pattern to match the desired file format (prefix + date):

Arrays.sort(files, Comparator.comparingLong(File::lastModified).reversed());
Pattern pattern = Pattern.compile("^" + filePrefix + "\\d{4}$");

7.erate through the sorted files

File latestFile = null;
for (File file : files) {
    if (pattern.matcher(file.getName()).matches()) {
        latestFile = file;
        break;
    }
}

Check if a matching file was found and retrieve its nam

if (latestFile != null) {
    String latestFileName = latestFile.getName();
    // Perform renaming or any other operations with the file
} else {
    // No matching file found
}
