Question

有人可以向我解释为什么它找不到'符号'我已经做了一点点查找，但这对我没有意义。我正在使用IDE。（下面有一个红线：jTextField1ActionPerformed（evt）;）与第二个块相同的东西，第三个是IDE中的编译信息。有人可以解释一下，BTW IDE这样做，所以我不知道该怎么做。问题领域1：

 jTextField1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jTextField1ActionPerformed(evt);
}

 jTextField3.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent evt) {
                jTextField3ActionPerformed(evt);
            }
