print text show the file path using Java

Question

I need a java method to check text

Answer 1

You can compare size file by file, saving the equal size files into an arraylist and then printing this ArrayList info.

Is a very simple and rude method, maybe if u have a folder with lot of links or things like this will not be working ok.

If u want to investigate more, u can use checksum to check this, but you need knowledge of this aspect.

Answer 2

If you want to do this in Java, you can use commons.io Apache library, with the method iterateFiles to get the files inside the directory, and the method contentEquals to check if two files have the same content.

Imports

import org.apache.commons.io.FileUtils;

Code

final String path = "C:/...";
List<File> files = new ArrayList<>();
Iterator iterator = FileUtils.iterateFiles(new File(path), null, false);
while(iterator.hasNext()){
    // Compare with the rest of the files in the array
    final File file = iterator.next();
    for (int i = 0; i < files.size(); i++) {
        if (FileUtils.contentEquals(file, files.get(i))) {
            // Here you can show the file path name
        }
    }

    // Add the file to the array
    files.add(file);
}
