要设置过滤条件，您可以使用FileFilter类来指定需要监视的文件或文件夹。以下是一个例子，演示如何设置过滤条件：

import java.io.File;

public class FileMonitor {
    
    private File directory;
    private FileFilter filter;
    
    public FileMonitor(File directory, FileFilter filter) {
        this.directory = directory;
        this.filter = filter;
    }
    
    public void startMonitoring() {
        // Start monitoring the specified directory using the specified filter
        // Implement your monitoring logic here
    }
    
    public static void main(String[] args) {
        File directory = new File("path/to/directory");
        
        // Create a filter to only monitor files with a specific extension
        FileFilter filter = new FileFilter() {
            @Override
            public boolean accept(File file) {
                return file.getName().endsWith(".txt");
            }
        };
        
        FileMonitor monitor = new FileMonitor(directory, filter);
        monitor.startMonitoring();
    }
}
