[英]Netbeans “illegal start of type” error
I am following the Netbeans CRUD Application tutorial (modified to use my own database) and I am getting this error that I can't figure out at all. 我正在跟踪Netbeans CRUD应用程序教程(已修改为使用我自己的数据库),但遇到了我根本无法弄清的错误。
The error says "illegal start of type ';' 错误显示为“类型';'的非法开始”。 expected, cannot find symbol
预期,找不到符号

I know it is something simple but I cannot figure out what or how to fix it. 我知道这很简单,但是我无法弄清楚该如何解决。 I am sure it is a misplaced ';'
我确定这是放错位置的';' or something?
或者其他的东西?
As you are no doubt aware I am new to Java. 毫无疑问,您是Java的新手。
I have done everything the tutorial says but can't seem to figure this out... 我已经完成了本教程所说的一切,但似乎无法弄清楚……
Any help would be grand! 任何帮助将是巨大的!
Thanks 谢谢
I think you missed the method block..May be you would like to wrap below block of code in some method. 我认为您错过了方法块。可能是您希望在某些方法中包装下面的代码块。
EntityManager entityManager = Persistence.createEntityManagerFactory("catalogueLibraryPU").createEntityManager();
Query query = entityManager.createNamedQuery("Photos.findAll");
List<Photos> resultList = query.getResultList();
for (Photos c : resultList) {
jTextArea1.append(c.getTitle() + " (" + c.getLocation() + ")" + "\n");
}
