Replace double quotes (")

Question

Here my line is as follows: -

sTest = AAAAA"1111 

I want to replace the double quote with a backslash and double quotes ( \" )

I need String Like

 sTest = AAAAA\"1111 

Answer 1

 String escaped = "AAAAA\"1111".replace("\"", "\\\""); 

• Doc API for String.replace

(Note that the replaceAll version handles regular expressions and is redundant for this particular situation.)

Answer 2

string.replace("\"", "\\\"")

You want to replace " with \" . Since both " and \ have a certain meaning, you should avoid them correctly by adding the previous \ before each.

So " → \" and \" → \\\" . And since you want the compiler to understand that it is String, you need to wrap each line with double quotes So " → \" and "\"" → "\\\"" .

Answer 3

Although the other answers are correct for a specific situation, for more complex situations you can use StringEscapeUtils.escapeJava (String) from Apache Commons Lang.

 String escaped = StringEscapeUtils.escapeJava(string); 

Answer 4

 System.out.println("AAAAA\"1111".replaceAll("\"", "\\\\\""));
