Answer 1

You need to add a filter:

JFileChooser jf = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("TEXT FILES", "txt", "text");
jf.setFileFilter(filter);

Answer 2

You could do that by using FileFilter.

Create a Filefilter with the necessary conditions. Set this file filter to the JFileChooser, and launch it.

Answer 3

Here some examples

fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("Images", "jpg", "png", "gif", "bmp"));
fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("*.pdf", "pdf"));
fileChooser.addChoosableFileFilter(new FileNameExtensionFilter("*.txt", "txt"));
