Replace \ from string

Question

I want to remove "" from the below string, and for that I am using

String orderDetailsDb =  "[{\"productId\":\"2814ff15-2fcf-4dc8-bf90-032e77a73e6b \",\"productName\":\"Garlic Oil 30 Capsules\",\"quantity\":6,\"price\":63.06,\"discount\":0,\"discountedPrice\":63.06,\"rowPrice\":\"\",\"gtinCode\":\"9324917000603\",\"accountNumber\":\"50138\",\"isPromo\":\"\"}]"

orderDetailsDb.replaceAll("\\", "");

but this is throwing

java.util.regex.PatternSyntaxException: Unexpected internal error near index 1
\

What are the square brackets around the string literal? That's not valid Java. — Stephen C

Those backslashes aren't really there, they are just visible to escape the double quotes inside a Java string literal. — Tim Biegeleisen

If you want to remove the " in your string you can replace the " but you have to escape it because of course it would close the string in your argument.

orderDetailsDb.replaceAll("\"", "")

or better use just replace

orderDetailsDb.replace("\"", "")

because replaceAll uses regex internally and you don't need a regex expression here.

the \ " in your strings are not there, they are just used to escape the "
