Need help fixing PHP Parse Error Code for CF7 Plugin

I got an error message saying
“Parse error: syntax error, unexpected ‘print’ (T_PRINT), expecting identifier (T_STRING) in /home/celticcornernj/public_html/wp-content/plugins/contact-form-7/admin/includes/welcome-panel.php on line 9”

<?php

abstract class WPCF7_WelcomePanelColumn {

	abstract protected function icon();
	abstract protected function title();
	abstract protected function content();

	public function print() { // This is line 9.
		$icon = sprintf(
			'<span class="dashicons dashicons-%s" aria-hidden="true"></span>',
			esc_attr( $this->icon() )
		);
