FileWriter报错重名报错

//代码正确但是怎么一直报错

package come.itwu.d4_字符流;

import java.io.Writer;

public class FileWriter {
public static void main(String[] args)  throws  Exception {
	Writer fw = new FileWriter(new file("data.txt"));
	
}
}

　　

报错内容：file cannot be resolved to a type

最后排除发现new FileWriter与类名冲突，报错

将类名改变后错误消失。
