Title Body

I am getting a long list of errors. Can anyone suggest to me where I am going wrong with GroupLayout . layout.setHorizontalGroup( layout.createSequentialGroup() .addComponent(new JLabel("Enter Book Name")) .addComponent(new JTextField("TextField", 20)) ); Error: Exception in thread "main" java.lang.IllegalStateException: javax.swing.JTextField[,0,0,0x0,invalid,layout=javax.swing. plaf.basic.BasicTextUI$UpdateHandler,alignmentX=0.0, alignmentY=0.0,border=javax.swing.plaf.BorderUIResource$ CompoundBorderUIResource@3d0bbf9e,flags=296,maximumSize=, minimumSize=,preferredSize=,caretColor=sun.swing.
