If-statement doesn't respect my condition [duplicate]

This question already has an answer here:

I have an If statement in Java but it doesn't funtion correctly. I put a condition but the if doesn't respect that.

My code :

btnNewButton.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            String name="";
            String surname="";
            name = txtName.getText().toString();
            surname = txtSurname.getText().toString();
            if (name!="" && surname!="") {
                msgAlarm.setText("<html>Insert all data<br/>before continuing!<html>");
                 Runnable runnable =
                         (Runnable) Toolkit.getDefaultToolkit().getDesktopProperty("win.sound.exclamation");
                 runnable.run();
            }else {
            System.out.println("Else Started");
            }

However when I run the program and the txtName and txtSurname are empty, Java run first statement. How can I resolve?
Many Thanks.
