它生成错误:

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
at wrs.mainWRS.main(mainWRS.java:70)


我做错了什么?

//编辑
这里只有这段代码是如何产生错误的。

package sof;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;

public class wrs{
    static File file = new File("C:\\Users\\Jan\\Desktop\\Test.txt");
    static FileReader filereader = new FileReader(file);
    static BufferedReader bufferedreader = new BufferedReader(filereader);

public static void main(String[]args){                  //<-- Line 12
    }
}


新的错误是:

线程“主”中的异常java.lang.Error:未解决的编译问题:

在sof.wrs.main(wrs.java:12)

最佳答案

您需要这样使用“ /”之一而不是这些“ \”:

static File file = new File("C:/Users/Jan/Desktop/eTest.txt");
