lbankName.setFont(f);
lname.setFont(f1);
lemailadd.setFont(f1);
lsubject.setFont(f1);
lmessage.setFont(f1);
setLayout(new GridLayout(6,2,8,8));
add(lbankName);
add(blabel);
add(lname);
add(tfname);
add(lemailadd);
add(tfemailid);
add(lsubject);
add(tfsubject);
add(lmessage);
add(tamessage);
add(submit);
add(reset);

}
// public static void main(String[] args) {
// BankApplet bankt = new BankApplet();
// bankt.init();
// }
}

Answer 1

lname.setFont(f1);这一行报错。
lname没有初始化。
需要在前面增加
lname = new Label("XXX");
