How to open a file using a JButton

Question

I have a file, we can call it 'example.txt' and I've already called the file in my program. I want to add functionality to open the file when a JButton, myButton is clicked. This is my code so far:

myButton.setText("Button");
 File example_file = new File("~/path/to/example.txt");
 myButton.addActionListener(new java.awt.event ActionListener(){
   public void actionPerformed (java.awt.event.ActionEvent evt){
     myButtonActionPerformed(evt);
   }
 });

private void myButtonActionPerformed(java.awt.event.ActionEvent evt){
   //open the file
}

I'm sure there is a very simple way to do this, but I haven't been able to find anything.

you have to read the contens of the txt file, save it to a String and then output the String — alexandre1985, Mar 21 '15 at 18:49
@alexandre1985 what if the file is not a txt file? Is there no way to actually open a file using JButtons? — Jud, Mar 21 '15 at 18:50

Desktop.getDesktop().open(new java.io.File("path to file"));

Just a suggestion: Learn C\C++ for these kind of jobs. I did.
