How to keep the backslash in string?

Assume I have a string input as

String str = "xxx---xxx\\\'hi\'xx";

When I try to print the string, it becomes below because of the backslash:

xxx---xxx\'hi'xx

How can I make the output still as

xxx---xxx\\\'hi\'xx

When the java compiler reads a literal string in a source file, it knows that the backslash is a special quoting character that is user to handle literaly the following character even if is was special, including the backslash itself.

So when you write String s = 'a\\b'; you have defined s as the string containing 3 characters, a, \ and b.

So if you want a number or backslash characters in a string, just write twice this number in your source code.

Backslash on its own is an escape character. Read more about it here.

In your case, you will have to print "xxx---xxx\\\\\\'hi\\'xx" to get the output as "xxx---xxx\\\'hi\'xx". You may also find and replace all "\" with "\\" in your string for automation.
