推荐答案

以下是您的全部答案： - ---------







Escape character

Here is all your answer :----------



Escape character

要在OUTPUT中显示的斜杠数量只需在CODE中加倍

例如for 2 slash

Number of slashes you want to display in OUTPUT just double it in CODE
e.g. for 2 slashes

System.out.println("D:\\\\"+name+".jpg");

和3加6

and for 3 add 6

两个斜线是正常的。编译器只接受其中一个，因为，如上所述，一个是转义字符。举例来说：

Two slashes is normal. The compiler only takes one of them, because, as said above, one is the escape character. Take for example:

Image myImage=new Image("D:\\image.jpg");

程序知道它必须访问文件D：\ image.jpg。删除一个斜线，你应该没问题。

好​​运。

The program knows that it must access the file D:\image.jpg. Delete one slash and you should be ok.
Best of luck.
