       JLabel textLabel = new JLabel("I'm a label in the window",SwingConstants.CENTER); 
       textLabel.setPreferredSize(new Dimension(300, 100)); 
       frame.getContentPane().add(textLabel, BorderLayout.CENTER);

Use . rather than / to specify the fully qualified class name when using java

java java1.TopLevelWindow

Also add a package declaration:

package java1;
