Backslash in java

Question

I have a problem with strings saved in a database, like this for example: \"311\\315_316\\336_337\". They have only one backslash and this is a problem in java. Wh

Answer 1

The data in the database is OK, and you don't have to replace anything. String literals, written directly in the Java code, must have their backslash escaped by another backslash:

String s = "311\\315_316\\336_337";
System.out.println(s); // prints 311\315_316\336_337

But if you get those values from the database, you don't have anything to do:

String s = resultSet.getString(1);
System.out.println(s); // should print 311\315_316\336_337
