Importing LinkedList in Java giving an error
提问by Ritam Das
I have created a class called 'Function' and want to create a LinkedList in it. So I have written the following code (Cropped to the problem area only).
我创建了一个名为“Function”的类，并想在其中创建一个 LinkedList。所以我写了以下代码（仅裁剪到问题区域）。
import java.util.LinkedList;
import java.util.ArrayList;
class Function{
ArrayList<Integer> arrayList = new ArrayList<Integer>();
LinkedList<Integer> linkedList = new LinkedList<Integer>();
protected void addbeg(){
}
}
In the import LinkedList line, I am getting the following error: "The import java.util.LinkedListconflicts with a type defined in the same file"
在导入 LinkedList 行中，我收到以下错误：“import java.util.LinkedList与在同一文件中定义的类型冲突”
and In the line where I declaring a variable linkedList of type Linked list LinkedList<Integer> linkedlist = new LinkedList<Integer>(), it is giving the follwoing error 'The type LinkedList is not generic; it cannot be parameterized with arguments '
并且在我声明 Linked list 类型的变量 linksList 的行中LinkedList<Integer> linkedlist = new LinkedList<Integer>()，它给出了以下错误“类型 LinkedList 不是通用的；它不能用参数参数化 '
Any help how to eliminate these error? I have seen some tutorial on Java LinkedList where they have written same code without getting any error. I should also mention that The ArrayList is running without any error.
任何帮助如何消除这些错误？我看过一些关于 Java LinkedList 的教程，他们编写了相同的代码而没有出现任何错误。我还应该提到 ArrayList 正在运行，没有任何错误。

The import java.util.LinkedList conflicts with a type defined in the same file
导入 java.util.LinkedList 与同一文件中定义的类型冲突
The error is really quite specific, it's saying that somewhere in the file you have:
该错误确实非常具体，它表示您在文件中的某个地方：
class LinkedList {
}
...or possibly interface LinkedListor enum LinkedList, though that latter seems unlikely.
...或可能interface LinkedList或enum LinkedList，尽管后者似乎不太可能。
Remove or rename that, or remove the importuse the fully-qualified name when using java.util.LinkedList(stronglyrecommend the former, not the latter).
删除或重命名，或删除import使用时使用的完全限定名称java.util.LinkedList（强烈推荐前者，而不是后者）。
