Method Example of Java Realizing Batch Modification of txt File Names

In this paper, an example is given to describe the method of modifying txt file names in batches by Java. Share it for your reference, as follows:

Recently, when doing the experiment of feature selection, it is necessary to modify the file name under 1 batch, and make 1 record here.

import java.io.File;

public class RenameTxt
{
    public static void renameTxt(File file)
    {
        if (file.isDirectory())
        {
            File[] files = file.listFiles();
            System.out.println(files.length);
            for (File f : files)
            {
                System.out.println(f.getName());
                String originalName = f.getName();
                System.out.println(originalName);
                String newName = "10" + originalName;
                String newFilePath = "F:\\Develop_Code\\workspace\\Research\\3. Feature selection \\TrainingSet\\C000010";
                File newFileName = new File(newFilePath + "\\" + newName);
                synchronized(f)
                {
                    f.renameTo(newFileName);
                }
            }
        }
    }
}
