JFileChooser to open multiple txt files

Question

How can I use JFileChooser to open two text files and after I selected these files, I want to compare them, show on the screen etc. Is this possible?

Answer 1

You can use:

JFileChooser chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(true);

// Show the dialog; wait until dialog is closed
chooser.showOpenDialog(frame);

// Retrieve the selected files.
File[] files = chooser.getSelectedFiles();

You can then use the file handles returned to do the compare.
