What is the backslash character (\\)?
Solution 1:
\ is used as for escape sequence in many programming languages, including Java.
If you want to
- go to next line then use
\nor\r, - for tab use
\t - likewise to print a
\or"which are special in string literal you have to escape it with another\which gives us\\and\"
Solution 2:
Imagine you are designing a programming language. You decide that Strings are enclosed in quotes ("Apple"). Then you hit your first snag: how to represent quotation marks since you've already used them ? Just out of convention you decide to use \" to represent quotation marks. Then you have a second problem: how to represent \ ? Again, out of convention you decide to use \\ instead. Thankfully, the process ends there and this is sufficient. You can also use what is called an escape sequence to represent other characters such as the carriage return (\n).
