 System.out.println("Search Text 1 is:" + searchText1);
 System.out.println("Search Text 2 is:" + searchText2);
 file.close();

Answer 1

You can verify if the path is correct or not by creating file as

new File ("C:\\\\testdata.xls")

Then print the absolute path. Check if it is a valid path.

Answer 2

You probably have to be more specific. I'd imagine your file is in a subdirectory of C. If it is in a subdirectory include the hold path to the file. For example, "C:\\Users\\nicky\\Desktop\\MyProgram\\file.txt" (double backslashes)

Or you could just copy the file into your project folder and call it by its name. "file.txt"

Answer 3

我的文件路径正确但我的文件扩展名错误。
