我有一个关于切换按钮的基本问题：以下代码确实会产生所需的结果，但是，布尔值似乎应该相反。代码在编程上是否正确？
public class ToggleButton extends javax.swing.JFrame {

one.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
oneActionPerformed(evt);
}
});
all.setText("all channel");
all.addActionListener(new java.awt.event.ActionListener() {
