Question

我是java编程的初学者，我有一个问题要问你。我正在使用netbeans 8.0.2，我有这个错误：

------线程中的异常＆＃34; main＆＃34; java.lang.RuntimeException：无法编译的源代码 - 找不到符号符号：class Spacer location：class demineur.views.ParameterDialog at demineur.views.ParameterDialog.initComponents（ParameterDialog.java:59）在demineur.views.ParameterDialog。（ParameterDialog.java:12）at demineur.controllers.Controlleur。（Controlleur.java:32）at demineur.Demineur.main（Demineur.java:19）Java结果：1

我该怎么办？
