import java.awt.*; import javax.swing.*; JPanel middlePanel = new JPanel(); middlePanel.setLayout(new GridBagLayout()); GridBagConstraints cons = new GridBagContraints(); cons.weightx = 1.0; cons.weighty = 1.0; middlePanel.setBorder(new TitledBorder(new EtchedBorder(),"Display Area"));
When i use this code snippet(this is just a rough code snippet) i get errors like "can not find symbol GridBagContraints" and "can not find symbol TitledBorder","can not find symbol EtchedBorder". How to fix it?
