public class DBConnect {
/**

public static void main(String[] args) {
// TODO code application logic here
}
}
Netbeans highlights DBConnect as red with duplicate class error.
Netbeans 将 DBConnect 突出显示为红色，并出现重复的类错误。

this might be due to 2 classes with the same name in the same package
这可能是由于同一个包中有 2 个同名的类

If the file name doesn't match the class name, NetBeans 8.0.1 will report this as a duplicate class.
如果文件名与类名不匹配，NetBeans 8.0.1 会将其报告为重复类。

This also happens if your referencing the erroring class in a separate file in the same package, with the erroring class with an unmatching package path to the file where you are referencing erroring class.
如果您在同一个包中的单独文件中引用错误类，并且错误类与引用错误类的文件的包路径不匹配，也会发生这种情况。
For example file 1 some.incorrect.path.package
例如文件 1 some.incorrect.path.package
class_that_is_erroring{ }
class_that_is_erroring{ }
file 2 some.correct.path.package
文件 2 some.correct.path.package
class new_class{
类 new_class{
class_that_is_erroring myclass = null;
class_that_is_erroring myclass = null;
}
}
The package paths in both files must match each other and match the file system directory.
两个文件中的包路径必须相互匹配并匹配文件系统目录。
