    // Create the text component
    JTextComponent tc = new JTextArea("Initial Text");
    
    // Get length
    int docLength = tc.getDocument().getLength();
    
    // Get all text
    String text = tc.getText();
    
    try {
        // Get the first 3 characters
        int offset = 0;
        int len = 3;
        text = tc.getText(offset, len);
    
        // Get the last 3 characters
        offset = docLength-3;
        len = 3;
        text = tc.getText(offset, len);
    } catch (BadLocationException e) {
