试图让不同的jtextarea显示不同的值以响应另一个的值

Question

    JComboBox cBox = new JComboBox();
    cBox.addItem("Food"); String x = "Food";
    cBox.addItem("Shirt");
    cBox.addItem("Computer");
    cBox.setSelectedItem(null);
    cBox.setBounds(56, 127, 336, 27);
    contentPane.add(cBox);

    tPName = new JTextArea();
    tPName.setBounds(38, 227, 130, 26);
    contentPane.add(tPName);
    tPName.setColumns(10);

    tSName = new JTextArea();
    tSName.setBounds(262, 227, 130, 26);
    contentPane.add(tSName);
    tSName.setColumns(10);

    JButton btn = new JButton("New button");
    btn.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent e) {
            String name = (String) cBox.getSelectedItem(); //gets value of combo box
            tPName.setText(name); //text area displays value
            x; tSName.setText(F);
        }
    });

其中F字符串等于“值”。我正在使用eclipse，并且在如何让tSName打印响应tsPName中特定值的特定显示时遇到麻烦。
