我正在尝试从以下示例中学习: CustomDialog.java
但是,当我去编译它时,我收到以下错误:
OracleExample.java:47: error: cannot find symbol
private DialogDemo dd;
^
symbol: class DialogDemo
location: class CustomDialog
OracleExample.java:64: error: cannot find symbol
public CustomDialog(Frame aFrame, String aWord, DialogDemo parent) {
^
symbol: class DialogDemo
location: class CustomDialog
2 errors
任何帮助是极大的赞赏。
