GUI does not seem to display when I create it in my main method

I am having trouble getting my GUI to display, and I am certain I am missing something very simple. This is for homework. The class that contains the GUI is here :

public class SorcGUI extends JFrame{

    public void SorcGUI(){
        JTextArea jta = new JTextArea();
        JPanel jp1 = new JPanel();
        setTitle ("Sorcerers Cave");
        setSize (600, 600);
        setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

        JButton jbsearch = new JButton("Search");
        JTree jTree = null;
        JScrollPane treeView = new JScrollPane(jTree);

        JButton jbshow = new JButton("Show Contents");
        JButton jbread = new JButton("Import File");
        JScrollPane jsoutput = new JScrollPane(jta);
        JTextField jtfsearch = new JTextField("  enter search term  ");
        JLabel jlsearch = new JLabel("Search Type : ");
        JComboBox jcbsearch = new JComboBox <> ();
        jcbsearch.addItem ("index");
        jcbsearch.addItem ("Type");
        jcbsearch.addItem ("weight");

        //create a panel to hold the buttons and text fields

        jp1.add(jbread);     
        jp1.add(jbshow);  
        jp1.add(jtfsearch);
        jp1.add(jlsearch);
        jp1.add(jcbsearch);        
        jp1.add(jbsearch);
        jp1.add(treeView);


        //add the components to the GUI
        add(jp1, BorderLayout.PAGE_START);
        add(jsoutput, BorderLayout.CENTER);


        setVisible(true);

        jbread.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                SorcCave sc = new SorcCave();
            }
        });
        jbshow.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println("show");
            }
        });        
        jbsearch.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                System.out.println("search");
            }
        });

And the way I am creating the GUI is simply adding the following to my main method:

SorcGUI gui = new SorcGUI();

The program simply goes form run to build successful in three seconds, never showing the GUI. I am trying to clean up my projects by getting the GUI stuff into it's own class file. Thank you for any help.

Remove the void keyword from the constructor of SorcGUI so the components can be added to the parent container

public SorcGUI() {

I copy-pasted your code and commented the jbread action method and it works in a new Java Project in Eclipse IDE.

I only removed the 'void' from the constructor method.
